Hmm. Try counting the side of the shape and add the sides. Using the sides as numbers you may be able to solve the problem.
150 lbs on Earth is equal to 50 pounds on Mars
60 lbs on Earth is equal to _____
Set up a proportion.

Cross multiply.


The person would weigh 20 lbs on Mars.
Answer:
A=-2; B=-1
Step-by-step explanation:
3a - 2b + 4 =0
2a -5b -1 = 0
Let's multiple the top equation by 2, and the bottom by -3, and then use addition.
[3a - 2b + 4 =0]*2
[2a -5b -1 = 0]*(-3)
6a-4b+8=0
-6a+15b+3=0
Now add the two equations together:
11b + 11 = 0
Subtract 11 from both sides
11b = -11
Divide both sides by 11
b=-1
Substitute in the first equation:
3a - 2(-1) + 4 = 0
Simplify to get 3a+6 = 0
Subtract 6 from both sides to get 3a = -6
Divide both sides by 3 to get a=-2
