1) 65+57= 122
180-122= 58
2) 40+90=130
180-130=50
3) 130+20=150

I think the answer is (0,2)
Just say if a lb cost $2.17 divide 2.17 by 4 which is 0.5425 and 0.5425 times 3 = 1.6275 and 2.17 + 1.63 which is rounded = 3.7975
Answer: y=-2/5x+2
Solving Steps:
2x+5y=10 - Move the variable to the right
5y=10-2x - Divide both sides by five
y=2-2/5x - Reorder the terms
y=-2/5x+2
