Answer:

1) The question is aimed to determine the number that Laura is trying to come up with.

Such question is solved by stating an algebraic equation from the word statement, which is done step by step.

2) Using the name x for the unknown, the expression "three less than 8 times the number" is translated to: 8x - 3

3) The expression "half of 16 times the number after it was increased by 1" is translated to: (1/2) (16x + 1)

4) Finally, since they are equal, you can set the equation:

8x - 3 =  (1/2) (16x + 1)

5) And solve for x in this way:

i) Distributive property:

8x - 3 = 8x + 1/2

ii) At this stage you can see that the both 8x terms (on the left and on the right) cancel each other, which leads to the impossibility to determine the value of the unknown:

-3 = 1/2 which is alwasy false, meaning that the equation has no solution.

Laura can’t find a number that works because the equation is inconsistent and has no solution.

In order to solve this word problem, we would assign a variable to the unknown number, and then translate the word problem into an algebraic equation as follows:

Let the variable n represent the unknown number.

Based on the statement "Three less than eight times the number is equal to half of 16 times the number after it was increased by one," we can logically deduce the following algebraic equation;

8n - 3 = 1/2 × (16n + 1)

16n - 6 = 16n + 1

16n - 16n = 1 + 6

0 = 7 (False).

Therefore, this equation has no solution because the coefficients are the same on both sides.

Answer:

y = (8/5)x + 15

Step-by-step explanation:

First change the equation to standard form (y=mx+b)

5x + 8y = 16

8y = 16 - 5x

y = - (5/8)x + (16/8)

y = - (5/8)x + 2

Perpendicular Lines have the inverse opposite sign of slope

[For example: inverse opposite sign of 2 is - (1/2)]

Original equation slope (m) : - (5/8)

2nd Equation (m) : 8/5

After finding the slope, plug in the slope and points the standard form equation (y=mx+b)

Point: (-5,7)     x : -5     y : 7

Slope (m) : 8/5

y = m x + b

7 = (8/5) (-5) + b

'b' is the y-intercept and the last thing to solve for the equation

7 = - 8 + b

15 = b

Now, put the slope (m) and y-intercept (b) back into the equation

y = (8/5)x + 15

Step-by-step explanation:

(3 × 10) × 8 = 3 × (10 × 8)

It's an Associative Property of addition:

(a + b) + c = a + (b + c)

Check it:

Left side: (3 × 10) × 8 = 30 × 8 = 240

Right side: 3 × (10 × 8) = 3 × 80 = 240

B. 54π yd^2

Step-by-step explanation:

On god it is right trust mee!    

Answer: Our required area is 54π sq. yd.

Step-by-step explanation:

Since we have given that

Diameter of an ice skating = 44 feet

Radius of an ice skating = 22 feet

as we know the formula for area :

Area would be

[tex]\pi r^2\\\\=\pi \times 22^2\\\\=484\pi\ ft^2[/tex]

As we know that

9 sq ft = 1 sq yd

So, it becomes,

[tex]\dfrac{484\pi}{9}=53.77\pi\ yd^2\approx 54\pi\ yd^2[/tex]

Hence, our required area is 54π sq. yd.

Answer:

Thus, to make 4 pecan pies one need to buy approximately 1.3 pounds of pecan.        

Step-by-step explanation:

We are given the following information in the question:

Number of pecan pies to be made = 4

Pecan required to make 1 pie = [tex]1\frac{1}{2} \text{ cups}[/tex]

Pecan required to make 4 cups =

[tex]4\times 1\frac{1}{2} = 4\times \frac{3}{2} = 6\text{ cups}[/tex]

Now, 1 bag of pecan has a serving size of 1 cup . Hence, we need to buy 6 such bag.

Now, weight of one bag = 99 grams

Weight for 6 cups of pecan = [tex]6\times 99 = 594\text{ grams}[/tex]

We know that:

1 gram = 0.00220462 Pounds

594 grams of pecans = [tex]594\times 0.00220462 =1.30954428 \text{ pounds of Pecan}[/tex]

Thus, to make 4 pecan pies one need to buy approximately 1.3 pounds of pecan.

To solve this problem, first determine the information you need to answer. As we need to make 4 pecans of the pies, take the values for the one piece and multiply it with four.

To make 4 pecans pies one will required to by 1.30 pounds of pecan.

Given information:

Number of pecan pies to be made is 4

The pecan needed to make 1 pie is [tex]1.5[/tex]  cups.

Now, Pecan required to make 4 cups will be:

[tex]4 \times 1.5 = 6[/tex] cups.

As, 1 bag of pecan has a serving size of 1 cup

Hence, we need 6 such bags.

Now, weight of the bag is 99 grams

so,

weight of 6 such bags will be

[tex]=6\times 99\\=594 \;\text{gm}[/tex]

And we have

[tex]1 \; \text{gm}=0.00220462 \; \text{pound}[/tex]

So,

594 grams of pecans = [tex]594\times 0.00220462[/tex]

[tex]=1.3095 \;\text{pounds}[/tex]

Hence, to make 4 pecans pies one will required to by 1.30 pounds of pecan.

Answer:

The value of x is [tex](+/-)\sqrt{6}[/tex]

Step-by-step explanation:

The question in English is

Find the value of x so that the distance between the given points is 2V5 units.

(2x - 1,2) and (1 + x,x + 4)

we know that

the formula to calculate the distance between two points is equal to

[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]

substitute the values

[tex]d=\sqrt{(x+4-2)^{2}+(1+x-2x+1)^{2}}[/tex]

[tex]d=\sqrt{(x+2)^{2}+(-x+2)^{2}}[/tex]

[tex]d=\sqrt{x^2+4x+4+x^2-4x+4}[/tex]

[tex]d=\sqrt{2x^2+8}[/tex]

Remember that

[tex]d=2\sqrt{5}\ units[/tex]

substitute

[tex]2\sqrt{5}=\sqrt{2x^2+8}[/tex]

squared both sides

[tex]20=2x^2+8\\\\2x^{2}=12\\\\x^{2}=6\\\\x=(+/-)\sqrt{6}[/tex]

therefore

The value of x is [tex](+/-)\sqrt{6}[/tex]

Answer:

The simplified form of \((2+1)\cdot 3\div 3^{2}\).

Final answer:

Upon examining the prices of the three cars and calculating the potential original price before rounding, we find that all three cars could have a maximum price change of £49 when rounded to the nearest £100. Therefore, all cars have the same greatest potential change in price.

Explanation:

To determine which car's price changes by the greatest amount when rounded to the nearest £100, we need to consider the possible original prices before rounding. The original price could be up to £49 above or £50 below the rounded price, as values are rounded up when they reach the halfway point (£50).

Car A

Price: £12,380. Possible price range before rounding: £12,350 to £12,429.

Car B

Price: £16,760. Possible price range before rounding: £16,750 to £16,809.

Car C

Price: £14,580. Possible price range before rounding: £14,550 to £14,629.

Now, we must calculate the maximum changes in price. The greatest amount of change occurs when the original price is at the extreme end of the range.

With each car having a possible maximum change of £49, it means that all cars could potentially have the same greatest amount of change.

Answer:

B. +29 + +18

Step-by-step explanation:

+18- -29 what you do is you make the minus signs addition because when you are subtracting a negative it becomes a positive.

+29 + +18 is your answer.

Your answer will be option B "+29 + +18." Equivalent means the same amount and according to the rules of KCC (Keep Change Change) +18 - -29 will convert into +18 + +29 which would equal 47 which is equivalent to option B.

[tex]+18 -29[/tex]

[tex]KCC=18+29[/tex]

[tex]18+29=47[/tex]

Option A -18 + 18 = 0

Option B +29 + +18 = 47

Option C -18 - +29 = -18 + -29 = -47

Option D -29 - -18 = -29 + 18 = -11

Therefore your answer is option B.

Answer:

n=68

Step by step explanation:

When a number n is increased by two means n+2 so we can put parenthesis around it

(n+2)/5 = 14  

now we solve for the equation (for the variable n)

First multiply both sides by 5 to isolate the parenthesis on the left side by itself

(n+2) = 14*5

then we can simply isolate n by itself by subtracting both sides by 2

n = 70 -2 = 68

n = 68

To find the value of n when [tex]\frac{(n + 2) }{5}[/tex]  = 14,  resulting in n = 68.

The question asks to define an equation based on a described operation with a given result, and then solve it to find the value of n. The operation described is increasing a number n by two, then dividing the result by five to get a quotient of 14.

To translate this into an equation, you would set up the following equation:

[tex]\frac{(n + 2) }{5}[/tex] = 14

To find the value of n, you would first multiply both sides by 5 to isolate n on one side:

n + 2 = 70

Then, subtract 2 from both sides to solve for n:

n = 68

Therefore, the value of n is 68. This solves the equation and provides the value that n must be for the operation to result in a quotient of 14.

Answer:

If you solved this, it wouldn't have a remainder. First you would solve the numbers in the parenthesis, (15 - 3), which is 12. Now it should look like, 12 ÷ 12 + 1. Next you divide 12 by 12 and that equals 1. And all you need to do now is add 1 + 1, which is 2. So your answer will be 2.

Answer:

2

Step-by-step explanation:

To be able to solve this equation, you would use PEMDAS. This stands for the order of operations, and which order you would do them in.  P stands for parenthesis, E stands for exponents, M stands for multiplication, D stands for division, A stands for addition, and S stands for subtraction. Using this order, you would solve what is inside the parentheses first. So, 15-3 is 12. Once this piece is solved, you would have 12÷12+1. Then, since you don't have any exponents or multiplication, you would skip to division. 12 ÷ 12 is 1. So then your equation would be: 1+1. 1+1 is equal to 2. So your answer is 2! There is not remainder in the solution of this problem.

Answer:

(4, 0 )

Step-by-step explanation:

A translation of 1 unit left, subtract 1 from the original x- coordinate

A translation of 2 units down, subtract 2 from the original y- coordinate

The rule is (x, y ) → (x - 1, y - 2 ), thus

(5, 2 ) → (5 - 1, 2 - 2 ) → (4, 0 )

The image point of (5,2) after a translation left 1 unit and down 2 units is (4, 0).

To find the image point of (5,2) after a translation left 1 unit and down 2 units, we need to subtract 1 from the x-coordinate and subtract 2 from the y-coordinate.

The translated image point would be (5-1, 2-2) = (4, 0).

So, the image point of (5,2) after the translation left 1 unit and down 2 units is (4, 0).

Answer:

If x-2 is a factor of p(x) = x^{4} - 3 x^{2} + 2 x - 8 ,then p(x)  = 0

Solution:

According to factor theorem of polynomials,  

x-a is a factor of polynomial p(x), if and only p(a)=0

Step 1:

Since x-2 is factor of p(x),

x - 2 = 0

x = 2

Step 2:

[tex]p(x) = x^{4} - 3 x^{2} + 2 x - 8 ------ (equation 1)[/tex]

By substituting x = 2 in equation 1,

[tex]p(x) = 2^{4} - 3(2)^{2} + 2(2) - 8[/tex]

p(x) = 16 - 3(4 ) + 4 -8

p(x) = 16 - 12 - 4

p(x) = 16 - 16

p(x) = 0

Since x - 2 is a factor of p(x)  , we get p(x)=0
