Answer:

Step-by-step explanation:
<u>Simplifying Rational Expressions</u>
If two or more rational expressions have the same denominator, the add and subtract operations are done only with the numerator. The final denominator will be the common of both.
The expression is:

Operating on the numerators:

Removing parentheses:

Answer:
79
Step-by-step explanation:
(58+88+80+70+ x)/5=75
75*5=296x
375=296x
x=375-296
x=79
Answer:
C. 8,624
Step-by-step explanation:
recall that the formula for circumference is
Circumference = 2πr ( = given as 85 meters)
hence,
85 = 2πr
r = 85/(2π)
given h = 15m
volume of cylinder
= πr²h
= π (85/2π)² 15 (using calculator and assuming π = 3.14)
= 8628.58
Comparing with the choices, the closest choice (within rounding error) is C. 8,624
