George is making a 8 gallons of tropical trip punch. he has already poured in 1 3/4 gal of pineapple juice and 2 1/2 gal of orange juice. the only other ingredient is 7-up. how much 7-up does george need?

4 + 5 7/9= 9 7/9

step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
