Answer:
-4
Step-by-step explanation:
PEMDAS
exponents -> 2^2 = 4
divide -> -36/4 = -9
add -> -9 + 5 = -4
Answer:
Step-by-step explanation:
Area = 1/2 * 2b * (5b - 7)
Area = 1/2 * 2b * (5b - 7) = 24
b * (5b - 7) = 24
5b^2 - 7b = 24
5b^2 - 7b - 24= 0
(b- 3 )(5b + 8) = 0
b = 3 This the only solution that works. b can't be minus
The base is 2b or 2 * 3 = 6

Answer:
As a percent: 115%
As a decimal: 1.15
As a fraction: 
Step-by-step explanation:
<u>Percentages</u>
Suppose Michael spends some amount of money on food, and that money is set at 100%. He leaves a 15% tip for the waitress.
Thus, he is really paying 100%+15% = 115% of the original price.
To express a percentage as a decimal, we just divide by 100:
115% = 115/100 = 1.15
The same division should be simplified instead of operated to express the percentage as a fraction:
115% = 
Simplifying by 5:
115% = 
Summarizing:
As a percent: 115%
As a decimal: 1.15
As a fraction:
