Answer to Problem 84CCR
The equation is
The record low temperature is
Explanation of Solution
Given:
The difference between the record and low temperatures in Columbus, Ohio, is
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 let’s assume that the low temperature is x and according to the question high temperature is
Thus, the equation is shown below,
Thus, the equation is
In order to solve the equation first subtract both sides by
Thus, the record low temperature is
