Weight varies directly with gravity. Buzz Aldrin weighed 150 pounds on Earth, but only 30 pounds on the moon. What is the weight of a
person who weighed 48 pounds on the moon?
Type the number only.

240

Step-by-step explanation:

Set up a proportion:

=

Cross multiply:

30x = 7200

x = 240

So, the person would weigh 240 pounds on Earth

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
