A grocery store receives a 180-pound crate containing six 10-pound bags of potatoes and an unknown number of 5-pound bags of potatoes.

There are 24 5-lb bags of potatoes.

Step-by-step explanation:

Total weight: 180 lb

Weight of six 10-lb bags of potatoes: 6 * 10 lb = 60 lb

180 lb - 60 lb = 120 lb

There are 120 lb of 5-lb bags of potatoes.

(120 lb)/(5 lb) = 24

There are 24 5-lb bags of potatoes.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
