A street sign is 104 inches tall. How tall is it in feet and inches.
ikadub [295]

Answer:

8 ft 8 in

Step-by-step explanation:

104/12 = 8.666...

This shows that there are 8 total feet because there are 12 inches in a foot

Then, multiply 8*12 to get 96 in order to get the remainder of the inches left that do not make up one whole foot.

Then subtract 96 from 104 (104-96) to get the remainder which is 8 inches.

-3=x/-9 please tell me how to solve this I’m way behind and trying to learn thank you :)
snow_tiger [21]

-3 = x/-9

To make this easier, I'll put it in normal numbers

(-3 = x/-9) -1

3 = x/9

Multiply both sides by nine to take out the division.

27 = x

Hope that this helped!
