I only know how to do # 7.
7. 4.5^2 + 6^2 = 7.5^2
20.25 + 36 = 56.25
56.25 = 56.25
yes, the card is a right triangle because A and B added together equals the same as C
I got you !

Steps To Solve:
8y - 3 = бу + 17
~Subtract 8y to both sides
8y - 3 - 8y = бу + 17 - 8y
~Simplify
-3 = -2y + 17
~Subtract 17 to both sides
-3 - 17 = -2y + 17 - 17
~Simplify
-20 = -2y
~Divide -2 to both sides
-20/-2 = -2y/-2
~Simplify
10 = y

Hence, the answer is

$72 - $30 = $42
It increased $42.
Now take this number and divide by the original number (first):
42 ÷ 30
This is 1.4, let's convert this to a percentage.
We now times it by 100
1.4 × 100
The answer is 140%
