The weight y of a object on Jupiter is proportional to the weight x of the object on earth. An object that weighs 150 ponds on earth would weigh 378.2 ponds on Jupiter. Write a equation the situation then determine how Much a rock that weigh 12.64 on Jupiter would weigh on earth.

5.02 pounds

Step-by-step explanation:

y = k*x

Where,

y = weight of a object on Jupiter

x = weight of the object on earth

k = constant of proportionality

An object that weighs 150 ponds on earth would weigh 378.2 ponds on Jupiter.

y = k*x

378.2 = k*150

378.2 = 150k

k = 378.2/150

= 2.5213

Approximately k = 2.52

determine how Much a rock that weigh 12.64 on Jupiter would weigh on earth

y = k*x

12.64 = 2.52*x

12.64 = 2.52x

x = 12.64 / 2.52

= 5.0159

Approximately x = 5.02 pounds

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
