yes it does have enough to cover the cube
Answer:
r = t - u - s
Step-by-step explanation:
To solve for r in terms of s, t, and u, means to have r on one side and have t, u, and s.
t = u - s + r
t - u = s + r
t - u - s = r
d=30-5c/2
Move all terms that don't contain d to the right side and solve
31.5
