Just divide 100% by 80% and multiply that answer by 5. I'm pretty sure that's how you do it.

Question
The Mulraney's home has 2,550 square feet of living space. A contractor is building an addition to their home that will increase the square footage by 8%. What will be the square footage of their home with the addition?
Solution 1
First we have to find out how much the Mulraney's square footage increases with the addition.  To do this, we should multiply the percent of expansion, 8% (0.08) by their current square footage (2, 550)

0.08 * 2,550 = 204

This means that the addition is adding 204 square feet to the Mulraney's house.

To find the total number of square footage, we just add the original (2,550 feet) to the addition (204).

2,550 + 204 = 2754

Therefore, the square footage of the Mulraney's home with the addition is 2754 square feet.
Question
Write the worlds as an algebraic expression. the width plus twelve. how do i do it?
Solution 1

Reason/Explanation:
It's asking us to write the words as an algebraic expression. "The width plus twelve." For starters, we don't know what the width is, so we use a variable, X. Now we add 12. So we use X + 12. The width is X, plus twelve.

-DustinBR
Solution 2
X + 12 correct

You have to find x then add 13
Question
The product of two numbers is 24 negative if one of the factor is -6 what is the other factors
Solution 1
The other factor is 4 because if you multiply a negative with a positive, you'll get a negative. -6 * 4 will give you - 24.
Question
Find the product of two numbers whose sum is 11 and difference is 3.
Solution 1

The two numbers are 7 and 4

Let the first number = x

let the second number = y

The sum of the numbers is 11, in algebra form x + y  = 11

The difference of the two numbers is 3, in algebra form, x - y = 3

To obtain the two unknown numbers, we solve the two equations;

from the first equation, x = 11 - y

substitute the value of x into the last equation;

(11 - y) - y = 3

11 - y - y = 3

11 - 2y = 3

2y = 11 - 3

2y = 8

y = 4

The value of x = 11 - 4 = 7

Thus, the two numbers are 7 and 4

Solution 2
All you would do is minus what you have, like 11-3= 8 which would be 8+3=11 and 11-8=3 which means now you have the sum of 11 and the difference of 3.

Question
Lara solved an equation incorrectly, as shown below: Step 1: 2x = 18 Step 2: x = 18 − 2 Step 3: x = 16 Which statement best explains why Step 2 is incorrect in Lara's solution? A) She did not divide 18 by 2. B)She did not add 2 to 18. C)She did not multiply 18 by 2. D) She did not multiply 18 two times.
Solution 1

We have been given the steps to solve the equation as

Step 1: 2x = 18

Step 2: x = 18 − 2

Step 3: x = 16

There is an error in step 2.

We have x is in multiplication with 2. So in order to get rid of 2 from the left hand side, we perform opposite operation of multiplication i.e. division.

So we must divide both sides by 2.

Therefore, A is the correct option.

A) She did not divide 18 by 2.

Solution 2
Question
What number is 21% of 450
Solution 1
Since percent means per hundred, you are basically asking how many is 21 per hundred of 450.

To calculate 21 of 450, we solve the the problem by using the following formula: (X*Y)/100 where X=21 and Y=450.

Thus, when we enter 21 and 450 into our formula, we get this:

First we multiplied 21 by 450 and then we divided that by 100. When we did this, we found the answer to be 94.5.

Therefore, 21 percent of 450 is 94.5.

Solution 2
21% of 450 is 94.5
Question
PLEASE HELP !Barry has an ice tray that makes ice cubes shaped like a cone with a diameter of 2 cm and height of 2 cm. To the nearest cubic centimeter, what is the volume of an ice cube from Barry's tray? 2 cm³ 8 ​cm³​ ​ ​ 25 ​cm³​ ​ ​ 101 ​cm³​ ​ ​
Solution 1
To the nearest cubic centimeter, the volume of an ice cube would be 2 cm³. The formula for a cone is πr²(h/3), and when you divide the diameter by 2, you get one, so the formula would turn into π1²(2/3), giving you the answer.
