Move all terms that don't contain c to the right side and solve.

Answer: c = 0

The formula C = 0.35y efficiently calculates the total cost of y apples at $0.35 each. It demonstrates a straightforward linear relationship between cost and quantity.

To find the total cost (C) of y apples priced at $0.35 each, you can use the equation C = 0.35y. This formula multiplies the cost per apple ($0.35) by the number of apples (y) to give you the total cost. For instance, if you want to buy 10 apples (y = 10), the calculation would be C = 0.35 * 10, which equals $3.50.

This equation works because it represents a simple linear relationship between the cost and the quantity of apples. Each apple adds $0.35 to the total cost. Therefore, by multiplying the cost per apple by the number of apples, you get the overall cost.

Remember, this formula assumes a constant price per apple. If the price were to change, the equation would need to be adjusted accordingly. This calculation is useful for budgeting and understanding the cost implications of buying a specific quantity of apples at a given price.

[tex]-11(9b-8)=(-11)(9b)+(-11)(-8)=-99b+88[/tex]

Answer:

Refer below

Step-by-step explanation:

5) 9x+2 = 119 (alternate angles of a parallel line)

Hence 9x = 117: x=29 degrees.

6) 12x-8 and 108 are supplementary

Hence 12x+100 = 180 Or 12x= 80 :

x = 20/3

7) 5x+7 = 8x -71

(since vertically opposite angles equal and corresponding angles equal)

3x= 78 or x = 26

8) 7x-61 = 4x-7:3x= 54 orx = 18

9) 9x+25 = 13x-19

4x = 44: x=11:  17y+5 = 13(11)-19

y -7

10) 9x-36 =180 : x = 24: 8y+17 = 6(24)-7

8y =120: y =15

11) 7x-23 =49+3x(exterior angle of triangle)

Or 4x = 72: x=18 : 3x =11y-1

y =5

12) 5x-38 = 3x-4

2x = 34 or x =17

7y-20 = 5(17)-38

= 47

y = 67/7

Answer:

x = 5

Step-by-step explanation:

First, we need to move all the x's onto one side:

-7x-3x+8x = -8-2

Then, we simplify:

-2x = -10

To find x, we need to divide each side by -2:

So then x = 5

The answer is the number 12. This is because if 12 is added to 24 it equals 36 and if 12 is multipled by 3 it is 36.

If a certain number is added to 24, the result is the same as if the number were multiplied by 3 the certain number is 12.

Let's assume the certain number is represented by "x."

According to the given information, if the number is added to 24, the result is the same as if the number were multiplied by 3. This can be written as the following equation:

x + 24 = 3x

Now, let's solve for "x":

Subtract "x" from both sides to isolate the "x" term on one side:

x + 24 - x = 3x - x

24 = 2x

Now, divide both sides by 2 to solve for "x":

x = 24 / 2

x = 12

Therefore, the certain number is 12.

Let's consider the first number to be [tex]f[/tex] and the second number to be [tex]s[/tex]. Based on the information in the problem, we can create the following equations:

[tex]f + 2s = 1[/tex]

[tex]2f + s = 14[/tex]

Now, we can solve the equations through systems of equations. One way of doing this is by multiplying one of the equations so that there is a term in both equations which can be removed by addition or subtraction. In our case, we can multiply the entire first equation by 2 to get:

[tex]2f + 4s = 2/tex]

[tex]2f + s = 14[/tex]

Now, subtract [tex]2f[/tex] from both equations to get:

[tex]3s = -12[/tex]

[tex]s = -4[/tex]

Now that we have found [tex]s[/tex], "plug" it back into an equation to find [tex]f[/tex]:

Hey there!!

Let's take the first number as ' x '

Let's take the second number as ' y '

First number + twice the second number is 1

x + 2y = 1 ------------ ( 1 )

Twice the second number + second number is 14.

2x + y = 14 ----------- ( 2 )

Now let's get them all together...

2x + y = 14 --- ( 2 )

Now, let's multiply the first equation with 2 ...

...................................................................................................................................................................

2x + 4y = 2 --- ( 1 )

2x + y = 14 --- ( 2 )

Now, let's subtract the second equation from the second...

...................................................................................................................................................................

2x + 4y = 2 --- ( 1 )

- ( 2x + y ) = - ( 14 )

...................................................................................................................................................................

2x + 4y = 2 --- ( 1 )

-2x - y = -14 --- ( 2 )

...................................................................................................................................................................

3y = -12

Divide by 3 on both sides...

y = -4

The second number is -4.

We have the first equation x + 2y = 1

We got the y value, now substitute the value of y to get the value of x

...................................................................................................................................................................

x + 2y = 1

x + 2 ( -4 ) = 1

x - 8 = 1

Add 8 on both sides

x = 9

step by step solution:

we will add similar elements.

[tex]10^{10}(7.14+3.21)[/tex]

= [tex]10^{10} (10.35)[/tex]

Now converting [tex]10^{10}[/tex] in decimal form we get 10000000000 (10 zeroes)

Now multiplying 10.35 with 10000000000 we get 103500000000 (8 zeroes)

or we can change it to exponential form like [tex]1.035\times10^{11}[/tex]

11 because when you count from the extreme right end '0' and come counting to the left side, you skip 11 numbers till you reach the first number '1'. And when you put a decimal after 1st number, so the last '0' is at the 11th place, that is why it is [tex]10^{11}[/tex] .

They place more emphasis on science.

Step-by-step explanation:

The enlightenment emerged in 18th-century, which brought ideas that were deeply influenced by reason, empiricism and classics.  It restructured the old Greek and Roman ideas to make new inventions, and was changing ideas due to reasoning. It was the idea behind the invention of sculpting, a new way of passing ideas or information to people more than through paintings.

Enlightenment initially started with assembling of ordinary materials by a process termed sculptural construction, did not mean exactly the same thing to everybody.

During the enlightenment, artists placed more emphasis on science.

The linear equation for the total cost of buying and using the new iPhone with Verizon is total cost = $899 + ($65 * 24), which simplifies to $2459 for 24 months.

To find the linear equation for the cost of buying and using the new iPhone with Verizon, we need to consider the initial cost of the iPhone and the monthly plan cost. Let's assume the initial cost of the iPhone X is $899 and the monthly plan is $65. We can represent the total cost after 24 months as a linear equation.

The equation can be written as:

total cost = initial cost + (monthly plan cost * number of months)

Since we want to find the total cost after 24 months, we substitute the values into the equation:

total cost = $899 + ($65 * 24)

Simplifying the equation:

total cost = $899 + $1560 = $2459

Therefore, the total cost after 24 months would be $2459.

Fran's fudge recipe, originally calling for [tex]2\frac{1}{2}[/tex] cups of sugar, would require [tex]2\frac{9}{10}[/tex] cups after she increases the sugar by 2/5 of a cup. The process involves converting mixed numbers to improper fractions, finding a common denominator, and then adding the fractions together.

If Fran's fudge recipe calls for [tex]2\frac{1}{2}[/tex] cups of sugar and she increases it by 2/5 of a cup, we first need to find the common denominator to combine these two fractions. To do this, we express [tex]2\frac{1}{2}[/tex] cups as an improper fraction, which is 5/2 cups (since [tex]2\frac{1}{2}[/tex] = 5/2). Then, we add 2/5 of a cup to it.

Steps:

Convert 2 1/2 cups to an improper fraction: [tex]2\frac{1}{2}[/tex] = 5/2.

Add 2/5 cup to 5/2 cups: To add these, we need a common denominator, which is 10. So, we convert 5/2 to 25/10 and 2/5 to 4/10.

Add the two fractions: (25/10) + (4/10) = (29/10).

Convert 29/10 back to a mixed number: 29/10 = [tex]2\frac{9}{10}[/tex].

Therefore, Fran uses [tex]2\frac{9}{10}[/tex] cups of sugar in her fudge recipe after the increase.

Answer:

The correct option is A.

Step-by-step explanation:

Total number of students at the school is 2,500.

In the given pi chart Pink, Yellow and Sky Blue color represent the percentage of students that under reported, accurately reported, and over reported their heights respectively.

From the graph we can conclude that the yellow portion is approximately one fifth of whole circle. It means the number of students that accurately reported their height is one fifth of total number of students.

[tex]2500\times \frac{1}{5}=500[/tex]

Therefore the number of students that accurately reported their height is 500. Option A is correct.

Answer:

Option A) 500

Step-by-step explanation:

We are given the following information:

Total number of students = 2500

From pie chart:

[tex]\text{Under Reported }= \displaystyle\frac{1}{5}\times 100\% = 20\%\\\text{Accurately Reported }= \displaystyle\frac{1}{5}\times 100\% = 20\%\\\text{Over Reported }= \displaystyle\frac{3}{5}\times 100\% = 60\%[/tex]

We have to find the number of students whose height were accurately reported =

[tex]\text{Number of students whose height were accurately reported }= \\\text{Number of students}\times \text{Percentage of students whose height were accurately reported}\\= 2500\times 20\%\\\\= 2500\times \displaystyle\frac{20}{100} = 2500\times \frac{20}{100} = 500[/tex]

500 students report their height accurately.

the answer is 62 units because of the way the kite looks. a kite has 5 to 4 sides and if you divide that you will get sixty two units per unit.

The perimeter of kite ACBO is 62 units. Therefore, option C is the correct answer.

The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions.

From the given kite ACBO, OB=7 uints and OC=25 units.

Here, ∠OBC=90° (Angle between radius and tangent is 90°)

By using Pythagoras theorem,  

BC²=OB²+OC²

25²=7²+OC²

625=49+OC²

OC²=625-49

OC²=576

OC=24 units

So, perimeter=2(a+b), where a and b are adjacent sides

= 2(7+24)

= 2×31

= 62 units
