jared is building a treehouse. he pays $75 for materials and pays his friend $12 per hour to him. if jared spends a total of $129 on building his tree house, for how many hours did his friend work on it?

I think the answer is 4.5 if you subtract 75 from 129 and divide by 12?

12.5 cm.

Explanation:

For every 2 kilo meters, there are 5 centimeters. 5 kilo meters is 2.5 times more than 2 kilo Meters. So you multiply 5 centimeters by 2.5 and that is the answer.

8 km.

Explanation:

If you divide 5 cm by 2, you get 2.5. So divide 2 km by 2.5 and that is how you get .8.
