Answer:

1. 23

2. 8

Step-by-step explanation:

1. 180-157 = 23

2. 15²+x²=(9+x)²

225 +x²=81+18x +x²

225-81=18x

144 = 18x

x = 144/18 = 8

19 is 6% of what number?
Lilit [14]
You have to be able to take the words written down and put them into mathematical symbols.  The word "is" means =, the word "of" means to multiply, "what number" is x, your unknown.  So translating that from words to an equation looks like this: 19 = .06x.  Divide both sides by .06 to get x = 316 2/3
