Answer:
54
Step-by-step explanation:

Parentheses (14 + 42 - 6) = 50:
⇒ 50/10 + 7²
Exponents 7² = 49:
⇒ 50/10 + 49
Multiplication/division 50/10 = 5:
⇒ 5 + 49
Addition/subtraction: 5 + 49 = 54
⇒ 54
Answer:
see below
Step-by-step explanation:
12(80 – x) = 816
Divide each side by 12
80-x = 816 /12
80-x = 68
Subtract 80 from each side
80-x-80 = 68-80
-x = -12
Multiply each side by -1
x = 12
James earned 80-12 = 68
Answer:
The pool can hold 3,136 cubic feet of water
Step-by-step explanation:
To know how much water the pool can hold, we need to find the volume of this swimming pool, because the volume is how much a container can hold.
The formula for volume is L*W*H (length times width times height)
Let's multiply!
28*16*7=3136
