Answer: 
Step-by-step explanation:
To solve for b, we want to use the Pythagorean Theorem as given.
b and 7 are the legs, and 12 is the hypotenuse.
[exponent]
[subtract both sides by 49]
[square root both sides]
Now we know .
Put the bigger decimal on top
Not sure what you're asking. are you wanting to solve 5 ( a - b), where b equals those two things listed below? If that's the case, I can definitely help. If not, please clarify.
Answer:
4x+20=31
Step-by-step explanation:
So one hour of bowling is 20 dollars and they bowled for one hour hence the 1x20 which is equal to 20. That is the base coast we add to the variable of x that is the cost of renting one pair of shoes. And since they rented 4 pairs of shoes you multiply x by 4 to get 4x. Add the 20 dollars they paid to bowl and it is 4x+20. They paid 31 dollars in total so equal the equation to 31. 4x+20=31. Solution is $2.75 per pair of shoes.

Answer:
ΔGHI and ΔDEF are similar by SSS criteria
Step-by-step explanation:
Consider triangle GHI and triangle DEF
In ΔGHI, GH = 2, HI =4 and GI = 3.5
In ΔDEF , DE =4, EF = 6 and DF = 7
GH/DE = 2/4 =1/2
HI/EF = 3/6 = 1/2
GI/DF = 3.5/7 = 1/2
The corresponding sides are in same ratio by SSS criteria
ΔGHI and ΔDEF are similar
