Sandy: 10x + 5
Kimmi: 25x
If we want to know when the fees will be the same, we set the equations equal to each other and solve for x:
10x + 5 = 25x
5 = 15x
x = 3
So the number of children has to be 3.
They didn't distribute the 3 before doing the addition in the second step. They should've added 15 to both sides because 3*5 = 15

❖ The area of a square with lengths of 7 inches is 49 inches.
In a square, all sides are equal so if one side is 7 inches, the rest of the sides are 7 inches. You multiply 7 x 7 because you only need 2 sides to find the area because the area of a square is l x w. (If another sides length is stated, that is the length that you will use.

<span>Simplifying
8k + 2m = 3m + k
Reorder the terms:
8k + 2m = k + 3m
Solving
8k + 2m = k + 3m
Solving for variable 'k'.
Move all terms containing k to the left, all other terms to the right.
Add '-1k' to each side of the equation.
8k + -1k + 2m = k + -1k + 3m
Combine like terms: 8k + -1k = 7k
7k + 2m = k + -1k + 3m
Combine like terms: k + -1k = 0
7k + 2m = 0 + 3m
7k + 2m = 3m
Add '-2m' to each side of the equation.
7k + 2m + -2m = 3m + -2m
Combine like terms: 2m + -2m = 0
7k + 0 = 3m + -2m
7k = 3m + -2m
Combine like terms: 3m + -2m = 1m
7k = 1m
Divide each side by '7'.
k = 0.1428571429m
Simplifying
k = 0.1428571429m</span>
