use the second expression to calculate the left-hand side of the first equation:
Add 10 to both sides if this equation to get
and divide both sides by 2
this proves that x = 17, give the two initial equations

Answer:
A) Volume of the pile of sand is 2411.7 in³ .
Step-by-step explanation:
Given : A pile of sand on the beach has the approximate shape of a cone with a diameter 28 in. and a height of 11.75 in.
To find : volume of the pile of sand.
Solution : We have given that diameter of cone = 28 in.
height = 11.75 in.
Radius = .
Radius = 14 in.
Volume of cone = .
Volume of cone = .
Volume of cone = 2410.47
Volume of cone ≈ 2411.7 in³.
Therefore, A) Volume of the pile of sand is 2411.7 in³ .
