Answer: a. w = V/eh, b. w = 7
Step-by-step explanation:
This is change of subject of the formula.
V = ewh and we are solving for w.
Therefore, e and h now becomms the coefficient of w because we don't need them.
Divide through by eh
(a) w = V/eh.
No to find the vakye of w given the values if V, e and h,
(b). w = 210/10x 3
= 7
