The weight y of an object on Mars is proportional to the weight x of the object on Earth. An object that weighs 70 pounds on Earth would weigh 28 pounds on Mars. Write an equation that represents the situation. Then determine how much a boulder that weighs 250 pounds on Mars would weigh on Earth.

An equation that represents the situation is y=

A rock that weighs 250 pounds on Mars would weigh _ pounds on Earth.

Answer:

  • 625 pounds

Step-by-step explanation:

Given:

  • Weight on Earth = 70 pounds
  • Weight on Mars = 28 pounds

As per given the proportion is:

  • y/x = 28/70 ⇔ y/x = 2/5

A rock that weights 250 pounds on Mars would weigh on Earth:

  • 250/x = 2/5
  • x = 250*5/2
  • x = 625 pounds
