Ared, green, and pink backpack are hanging on hooks on the classroom. the total weight of the 3 backpacks is 32 pounds. the red one weights 93/4 pounds. the green one weights 1/3 over 4 more. how much weights the pink one?

We let x be the weight of the red bag, y for the green bag and z for the pink bag. It was given that the total mass of the 3 bags is 32 pounds. Thus,

x + y + z = 32

It was given that the red bag or x weighs 93/4 pounds and the green bag or y weighs 1/12 of the red bag. Substituting the values given, we have:

(93/4) + (1/12)(93/4) + z = 32
z = 6.8125 lbs

Thus, the pink backpack weighs 6.8125 pounds.

The coordinates of point a right now is (-3,-1) you have to multiply these coordinates by a factor of 2 to get (-6,-2)
