A building is 5 times as tall as a tree. The total height of the building and the tree together is 48m
How tall is the Building?

40 m

Step-by-step explanation:

Let the height of the tree be x meters.

Therefore, height of building = 5x

According to the given information:

Height of (building + tree) = 48 m

z = 4

Step-by-step explanation:

First multiply both sides by the denominator, -4, to get rid of it. Now you have 8z + 4 = 36.

Next subtract the 4 on both sides to get 8z = 32.

Lastly divide 8 on both sides to get z = 4.

Hope this helped :)
