Question

The formula N = 7LH is used to determine N, the number of bricks needed to build a

wall that is L feet in length and H feet high. Solve the equation in terms of L.
and
A customer would like a wall constructed
that is 4 feet high. If the bricklayer wants to use all of the 1,820 bricks that he has
readily available, how long will the wall be?

Answer 1

L=65

Explanation:

1820=7L*4

divide 4 to both sides.

455=7L

divide 7 to both sides.

65=L

1820=7L*4

replace L with 65 then solve to get the answer.

1820=7*65*4 7*65*4=1820
