Abricklayer uses the formula n=7lh to estimate the number of bricks, n, needed to build a wall that is l feet long and h feet high. which of the following correctly expresses l in terms of n and h? a)l= 7/nh b)l= h/7n c)l= n/7h d)l= n/7+h

Option C

Explanation: Here we have the equation: N = 7LH

If we want to isolate L in one side of the equation, the steps are the following ones:

N = 7LH

First, divide both sides by the number 7, this does not affect equality.

N/7 = (7LH)/7 = LH

Now, we divide both sides of the equation by H.

N/(7H) = LH/H = L

Now we have the equation L = N/(7H), this mean that the right option is C.
