An equation and how much it weighs on earth
Answer to Problem 11GP
The equation as
The weight on Earth is
Explanation of Solution
Given:
The weight of an object on the Moon is one-sixth its weight on the Earth and if an object weighs 54 pounds
Concept Used:
- To get rid of a number in addition from one side, subtract the same number from both sides of equal sign.
- To get rid of a number in subtraction from one side, add the same number both sides of equal sign.
- To get rid of a number in multiplication from one side, divide the same number from both sides of equal sign.
- To get rid of a number in division from one side, multiply the same number both sides of equal sign.
Rules of Addition/ Subtraction:
- Two numbers with similar sign always get added and the resulting number will carry the similar sign.
- Two numbers with opposite signs always get subtracted and the resulting number will carry the sign of larger number.
Rules of Multiplication/ Division:
- The product/quotient of two similar sign numbers is always positive.
- The product/quotient of two numbers with opposite signs is always negative.
Calculation:
In order to find the equation here weight of an object on the Moon is one-sixth its weight on the Earth. Let x be the weight of an object on Earth
The weight of an object on the moon is
Object weight on the moon is
Thus, we can write an equation as
Then find the value of x as below:
Thus, the weight on Earth is
