1) 9x + 2 = x + 5 ---> 9x + 2 = 6

subtracted X from one side but not the other

2) 3(x-4) + 5 = 12 ---> 3x + 4 + 5 = 12

didn't distribute correctly: 3(x-4)

multiplied the X by 3 but not the -4

A tower made of wooden blocks measures 114 feet high. Then a block is added that increases the height of the tower by 8 inches.

satela [25.4K]

Answer:

4. 23 in

Step-by-step explanation:

The tower is 1 1/4 feet high, then 8 inches are added. Well, we can't just add those two numbers. We have to change the units! Change everything to inches.

1 1/4 feet is equal to 12 inches + 3 inches = 15 inches, because a foot = 12 inches.

Add 8 inches to 15, and you get 23 inches.

<u>The answer is 4. 23 in. </u>
