Answer:
x = 12
Step-by-step explanation:
First, eliminate the fractional coefficient 1/2, by multiplying all three terms by 2:
-24 + x = -12
Adding 24 to both sides isolates x: x = -12 + 24, or x = 12
Answer:
Step-by-step explanation:
Three equal sides, so lets find one by solving for x
6x + 16 = 9x-11
-3x = -27
x = 9
6(9) + 16 = 70
9(9) - 11 = 70
70(3) = 210 cm
Volume of a cube = (edge)^3
In this problem,
Volume = 216in^2
Edge = ?
Let's plug our values into the formula above.
216in^3 = (edge)^3
Take the cbrt of both sides.
6in = edge
The length of each edge = 6in
Add them up and you have your answer
