This is called a "substitution problem" is where you have variable that have defined values and plug them in value calculate the expression.
B = 3m + 2p # Starting equation
2 = (3)(5) + 2p # Substitution
2 = 15 + 2p # Multiplication
-13 = 2p # Subtract 15 from both sides
= p # Divide both sides from 2
p = # Use the reflexive property of equality
Hope this helps!
Answer: 4,188.79 u^3
Step-by-step explanation: Volume of a sphere is (4/3)pi•r^3
10^3 = 1000
(4/3) • pi • 1000 = 4,188.79 (rounded to 2 decimals)
