Answer: 56in³
Step-by-step explanation:
Let the volume of solid B de denoted as x. Based on the information given in the question, we can solve further by:
1/2 = 28/x
Cross multiply
1 × x = 2 × 28
x = 56
Therefore, the volume of solid is 56in³.
Answer:
Or did he?
Step-by-step explanation:
X= 23+8y
X represents the total
23 represents the base price
8 represents the price per extra hour
Y represents how many hours extra
Substituting x=6 and y=1 into both equations,

Since the second equation is not satisfied, (6,1) is not a solution to the system of equations.
