Walter asks to borrow $5 from Sharon on Monday, and another $8 on Tuesday. If he pays back $6 on Wednesday and borrows another $5 on Thursday, how much does he still owe Sharon on Friday

Answer:

Option C.

Option E.

Step-by-step explanation:

Let be "f" the price of a loaf of French bread, "w" the price of the grain bread and "c" the price of the cinnamon raisin bread.

We know that Melissa paid twice as much for the whole grain bread as for the French bread. This can be represented with this equation:

[tex]w=2f[/tex]       [Equation 1]

Since she paid $2.50 more for the cinnamon raisin bread than for the whole grain bread, we can write this equation:

[tex]c=w+2.50[/tex]       [Equation 2]

The total amount of money she spent was $11.25, then:

[tex]f+w+c=11.25[/tex]     [Equation 3]

Now you must substitute the Equation 1 into the Equation 2:

[tex]c=2f+2.50[/tex]      [Equation 4]

Substituting the [Equation 1] and the [Equation 4] into the [Equation 3], you get:

[tex]f+2f+(2f+2.50)=11.25[/tex]

If you simplify the equation, you get:

[tex]5f=8.75[/tex]

The correct equations that describe this situation are: A. f + f + (f + 2.50) = 11.25 and D. 2f + 2.50 = 11.25.

The correct equations that describe this situation are:

To solve this problem, let's assign variables to represent the prices. Let f be the price of a loaf of French bread. According to the information given, the whole grain bread costs twice as much as the French bread, so its price is 2f. The cinnamon raisin bread costs $2.50 more than the whole grain bread, so its price is (2f + 2.50). The total cost of the 3 loaves is $11.25, so we can set up the equations:

Simplifying these equations gives us the correct choices A and D.

Answer:

Total number of people in the line for the dunking machine is 8.

Step-by-step explanation:

Here, let us assume the number of people in the line for hoop shoot = 12

So, the number of people in the line for cakewalk

=  One- Third of the number of people in line for Hoop Shoot

= [tex]\frac{1}{3}  \times 12 = 4[/tex]

Also, the number of people in the line for dunking machine

=  2 x ( The number of people in line for Cakewalk)

=  2  x  4  = 8

Hence, the total number of people in line for the dunking machine is 8.

Final answer:

To find the number of people in line for the dunking machine when given the number in line for the hoop shoot, we calculate the cake walk line as one-third of the hoop shoot line, then double that for the dunking machine line, resulting in 8 people.

Explanation:

Given that the line for the dunking machine was twice as long as the cake walk line and that the cake walk line was one-third the length of the hoop shoot line, we can derive the relationship between the numbers of people in line for each activity.

First, since there were 12 people in line for the hoop shoot, and given that the cake walk line was one-third of this, the cake walk had 12 / 3 = 4 people in line.

Next, since the dunking machine line was twice as long as the cake walk line, it had 4 × 2 = 8 people in line.

Step-by-step explanation:

THe markup is the difference between the Selling Price and Cost.

As a percentage, we would get the markup in terms of cost.

First,

Selling Price = 4.50

Cost = 3.00

So,

Markup = SP - Cost = 4.50 - 3.00 = 1.50

As a percentage, we would divide the markup by cost and then multiply the answer by 100. That's:

1.50/3 = 0.5 * 100 = 50%

THe markup is 50%

C is the correct answer.

Answer:

C

Step-by-step explanation:

The markup is the difference between the Selling Price and Cost.

As a percentage, we would get the markup in terms of cost.

First,

Selling Price = 4.50

Cost = 3.00

So,

Markup = SP - Cost = 4.50 - 3.00 = 1.50

As a percentage, we would divide the markup by cost and then multiply the answer by 100. That's:

1.50/3 = 0.5 * 100 = 50%

The markup is 50%

C is the correct answer.

Mr. Jackson invested $800 at 6% per year and $ 2400  at 4 % per year

Mr. Jackson invested a sum of money at 6% per year, and 3 times as much at 4% per year.

Let the sum invested be ‘a’ and ‘3a’ at 6% per year and 4 % per year respectively

Also, his annual return totaled $144

We can form following equation on the basis of question:-

[tex]\begin{array}{l}{\text { Then, } \frac{a \times 6 \times 1}{100}+\frac{3 a \times 4 \times 1}{100}=\$ 144} \\\\ {\frac{6 a}{100}+\frac{12 a}{100}=144} \\\\ {\frac{6 a+12 a}{100}=144} \\\\ {\frac{18 a}{100}=144} \\\\ {18 a=14400} \\\\ {a=14400 \div 18}\end{array}[/tex]

a = $800

The amount of money invested at 6% = a = 800

The amount of money invested at 4 % = 3a = 3(800) = 2400

So, the amount of money invested at 6% is $800 and the amount of money invested at 4% is $ 2400

To determine the amounts Mr. Jackson invested, the problem was solved by setting up a simple equation and solving for x, which represents the amount at 6% interest. Mr. Jackson invested $800 at 6% and $2400 at 4% to receive a total annual return of $144.

The question involves solving a system of linear equations to find how much Mr. Jackson invested at two different interest rates if his total annual return is $144. To solve the problem, let's define the amount invested at 6% per year as x and the amount invested at 4% as 3x, since the latter is three times as much.

The interest from the investment at 6% would be 0.06x, and the interest from the investment at 4% would be 0.04 × 3x. Since these add up to $144, we can write the equation:

0.06x + 0.04 × 3x = 144

Solving this equation:

Since x represents the amount at 6%, Mr. Jackson invested $800 at 6% and $2400 at 4% because the investment at 4% is three times as much.

Answer:

Nathan's estimate would be greater than the actual product.

Step-by-step explanation:

Let a, b, c, d be natural numbers such that a<c and b<d

Multiplying a positive number on both sides doesn't affect the inequality

⇒a×b < c×b and c×b < c×d

⇒a×b < c×d

Here 67<70 and 36<40

∴67×36<70×40

Hence, Nathan's estimate would be greater than the actual product.

Answer:

The value in box of circle B is 3 and the value in box which belongs in both circle B and S is 6 and value which belongs in circle S is 1 and the value of box outside both the circle is 2.

Step-by-step explanation:

In given Venn diagram

ε = class of 12 pupils

pupils who have brother B = 9

pupils who have sister S = 7

pupils who have neither brother nor sister = 2

Hence the Venn diagram is drawn in the attachment for your reference.

n(E) =12

n(neither B nor S) = 2

So, n(B or S)= n(E) - n(neither B nor S)= 12-2=10

n(B) = 9

n(S) = 7

Now, addition theorem,

n(B or S) = n(B) + n(S) - n(B and S)

[tex]10=9+7-n(B\ and \ S)\\n(B\ and \ S) = 6[/tex]

So the value in box which is in both circle B and S is 6.

So the Box which contains only brothers = n(B) - n(B and S)  = 9 - 6 = 3

Value in box of circle B is 3.

So the Box which contains only Sisters = n(S) - n(B and S)  = 7 - 6 = 1

Value in box of circle S is 1.

There are 12 pupils in a class so, the number of pupils having both brother and sisters are 6 and the pupils had either brother or sister are 10.

Given :

Given that there are pupils in a class that is, n(E) = 12

Pupils who have brother, n(B) = 9

Pupils who have sister, n(S) = 7

Pupils who have neither brother nor sister, n(neither B nor S) = 2

So,  n(B or S) = n(E) - n(neither B nor S)

                      = 12 - 2 = 10

n(B or S) = 10

Now, through the addition theorem:

n(B or S) = n(B) + n(S) - n(B and S)

10 = 9 + 7 - n(B and S)

n(B and S) = 6

Step-by-step explanation:

Let the number be x. "Three times a number increased by 10" is mathematically translated as

3x + 10

"is equal" is mathematically translated as twenty less than six times the number" is mathematically translated as

6x - 20

The whole sentence "Three times a number increased by ten is equal to twenty less than six times the number" is translated as

3x + 10 = 6x - 20

We now solve the above linear equation to find the number x

3x - 6x = - 20 - 10

- 3x = - 30

x = 10

Check answer

Three times a number increased by ten : 3 × 10 + 10 = 40

Twenty less than six times the number : 6 × 10 - 20 = 40

Final answer:

The simple linear equation given can be solved by defining the unknown number as 'x', setting up the equation, and solving for 'x'. After isolating x on one side, the result is that x equals 10.

Explanation:

The question is a classic example of a simple linear equation in one variable. We can define a variable, let's call it x, to represent the number in question. The problem statement translates to the equation:

3x + 10 = 6x - 20

Now, let's solve for x by isolating it on one side of the equation:

Subtract 3x from both sides:

10 = 3x - 20

Add 20 to both sides to get:

30 = 3x

Finally, divide both sides by 3 to find x:

x = 10

Therefore, the number we are looking for is 10.

[tex]64=2 \cdot 2 \cdot 2 \cdot 2 \cdot 2 \cdot 2=2^6[/tex]

Step-by-step explanation:

Gabrielle and John each

wrote the prime factorization of 64.

64 can be break into 32 times 2

32 can be break into 16 times 2

16 can be break into 8 and 2

8 can be break into 4 times 2

4 can be break into 2 times 2

So 64 is equal to 2 times 2 times 2 times 2 times 2 times 2

[tex]64=2^6[/tex]

The question involves analyzing the prime factorization of the number 64, which should be 2¶. The correctness of Gabrielle and John's factorizations can be checked by ensuring the base is 2 and the power is 6. Any deviation from this would indicate a mistake in their factorization.

The question concerns the prime factorization of the number 64. A prime factorization is the expression of a number as a product of prime numbers. For the number 64, which is a power of 2, the prime factorization should be 2¶ since 64 is 2 multiplied by itself 6 times (2 x 2 x 2 x 2 x 2 x 2).

If Gabrielle and John wrote their prime factorizations of 64 differently, at least one of them has made an error. To verify if their prime factorizations are correct, they should end up with the same base number, which is 2 in this case, raised to the same power, which should be 6 for the number 64. Any other combination of numbers in the factorization would be incorrect, since 64 is not divisible by any other prime numbers.

When analyzing their work, one should check if they thoroughly factored the number down to only prime numbers and did not mistakenly include a composite number or an incorrect exponent in the factorization. To correct errors, divide the number progressively by the prime number 2 until the quotient is 1. Each division step represents an exponent in the prime factorization of 64.

A formula known as an equation uses the equals sign to denote the equality of two expressions. In other terms, it is a mathematical statement stating that "this is equivalent to that."

Given:

The cost of peaches =$2,

The cost of the mangos = $1.25,

Total money = $20,

10 × 2 + 1.25x = 20

Here, x is the number of mangos,

1.25x =  20 - 20

x = 0

Write the equation when Henry buys 4 peaches,

4 × 2 + 1.25x = 20

8 + 1.25x = 20

x = 20 - 8 / 1.25

Answer:

The width is 5 inches and the height is 18 inches.

Step-by-step explanation:

The area of a triangle can be calculated as:

A = w*h/2

where w is the width of the base, and h is the height.

then we have that:

w*h/2 = 45 in^2

and the height is 2 less than 4 times the width.

h = 4*w - 2in

then we have a system with 2 equations:

w*h/2 = 45 in^2

h = 4*w - 2in

We can replace the second one in the first one and solve it for w.

w*(4*2 - 2in)/2 = 45 in^2

2w^2 - w = 45in^2

2w^2 - w - 45in = 0

then we have to solve the quadratic equation:

the solutions are:

w = (1 +- √(1^2 - 4*2*(-45))/(2*2) = (1 + - √361)/4

where we have two solutions for w, one for each sign of the square root.

we obviously need to take the positive solution (because we can not have a negative length)

w = (1 + √361)/4 = 5in

now, we can replace it in the equation "h = 4*w - 2in" to get the height.

h = 4*5in - 2in = 18in

The width and height of the triangle can be calculated using the given information and the equations for the area of a triangle and the relationship between the width and height.

The subject of this question is algebraic problem solving, specifically involving the concept of an area of a triangle. First, we need to remember that the area of a triangle is calculated using the formula A = 1/2 * base * height. We know that the area equals 45 square inches, so we can write an equation: 45 = 1/2 * width * height. Additionally, the question states that height is two less than four times the width, which is another equation: height = 4 * width - 2.

Now, we can substitute the height (which is 4 * width - 2) into our formula for the area. This gives us the equation: 45 = 1/2 * width * (4 * width - 2), which will allow us to solve for the width of the triangle. After solving for the width, we can use the equation height = 4 * width - 2 to find the height of the triangle.
