Answer:
k = ( - 4 )
Step-by-step explanation:
7k + 2 = 4k - 10
( arrange all like terms together like variable aside and constant aside here )
7k - 4k = -10 - 2
3k = (-12)
k = ( -4 )
It is incorrect because the length of the unknown side is the square root of 7,225.
If you use the pythagorean theorem and plug in the values,
a^2 + 132^2 = 157^2
a^2 + 17424 = 24649
-17424 -17424

a^2 = 7225
If you square root it, the final answer would be 85.
The answer would be B, 27 cups of onions to make 117 cups of salsa
She started with x boxes.
Then she bought 7 more, so now she has x + 2.
Then half of the boxes were destroyed.
She now has (x + 7)/2.
She has 22 boxes.
(x + 7)/2 = 22
x + 7 = 44
x = 37
She started with 37 boxes.
