If the weight of 2,290 steel balls is 3.18 kg, find the number of balls in 8.87 kg. Round the answer to the nearest integer, the nearest ball.

2290 steel balls weigh 3,180 grams so each ball weighs 1.3886462882

grams.  If you had a 8.87 kilograms of those balls they would number

8,870 grams /  1.3886462882 = 6,388 steel balls

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

a is the right answer
