Andre tried to solve the equation below. What was his mistake?
1/4(x+12)=2
1/4(x+12)=2
1/4x= -10
x= -40

30 people weigh 160 pounds or more

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
