The weight y of an object on jupiter is proportional to the weight x of the object on earth. an object that weighs 150 pounds on earth would weigh 379.2 pounds on jupiter. write an equation that represents the situation. then determine how much a rock that weighs 12.64 pounds on jupiter would weigh on earth. an equation that represents the situation is y= . a rock that weighs 12.64 pounds on jupiter would weigh pounds on earth.

Answer

As given

The weight y of an object on Jupiter is proportional to the weight x of the object on Earth.

i.e

y = kx

where k is the constant of proportionality.

An object that weighs 150 pounds on Earth would weigh 379.2 pounds on Jupiter.

put in the eqaution

y = kx

379.2 = k × 150

k = 2.528

As given

A rock that weighs 12.64 pounds on Jupiter .

put in the equation

y = kx

12.64 = 2.528 × x

x = 5 pounds

Thus

A rock that weighs 12.64 pounds on Jupiter would weigh 5 pounds on Earth.

Therefore

y = A rock that weighs 12.64 pounds on Jupiter would weigh 5 pounds on Earth.
