Gabriel is at the grocery store, and wants to figure out his total cost before he gets to the register. He bought 2.5 pounds of apples that are x dollars a pound and 2 bags of lettuce for y dollars each. Which expressions would represent his total cost? Check all that apply

2.5 x + 2y

Step-by-step explanation:

We know that he bought 2.5 pounds of apples that are x dollars a pound and 2 bags of lettuce for y dollars each.

2.5 pounds of an apple  = x dollars.

2.5 pounds of an apple/cost  = 2.5 x

2 bag of lettuce = y dollar(s).

2 bas lettuce/cost = 2y

Expression: 2.5 x + 2y

Therefore 2.5 x + 2y would represent his total cost.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
