1&1/2n = 3&4/9

17x = -11/30

4/13x = 0

thomas calculates that he will need 86 hours to build a boat. he can work on the boat 8&3/5 hours per week. how many weeks will it take thomas to build the boat?

-5/7x = 9/10

-3b = 2/3

3&1/9a = 3/7

1&1/2m = 1&3/4

1/8d = 1/4

3/7x = 1

the chandra satellite telescope views x-rays in space. it orbits as much as 87,000 miles above earth. this is about 1/3 of the distance to the moon. about how far away is the moon?

descrobe how you would solve & check the equation 2/3x = 3
