Lynne bought a bag of grapefruits, 1 5/8 pounds of apples and 2 3/16 pounds of bananas. the total weight was 7 1/2 pounds. how much did the bag of grapefruit weigh?

  3 11/16 pounds

Step-by-step explanation:

The third item in the group had a weight that is the difference between the total and the sum of the two other items:

  bag weight = (7 1/2) - ((1 5/8) +(2 3/16))

It can be convenient to use a common denominator of 16, so this is ...

  bag weight = 7 8/16 - (1 10/16 + 2 3/16)

  = 7 8/16 - (3 13/16)

  = (7 -3) + (8/16 - 13/16)

  = 4 - 5/16

  = 3 11/16

The weight of the bag of grapefruit was 3 11/16 pounds.

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
