To evaluate 8k−h(the power of 3)+8y÷r when k=4, h=2, y=5, and r=8, we substitute the given values into the expression:
8(4)−2³+8(5)÷8
Simplifying:
32−8+40÷8
32−8+5
24+5

Therefore, the correct answer is 29.

To find the sum of the equation 7 + p = 15, we need to isolate the variable p on one side of the equation. Subtracting 7 from both sides:
7 + p - 7 = 15 - 7
p = 8
Therefore, the sum of the equation is 8.
