Given
5(x + 27) ≥ 6(x + 26)
Find
The solution set of x
Solution
Eliminate parenthses.
... 5x + 135 ≥ 6x + 156
Subtract 5x+156
... -21 ≥ x
The solution set is all real numbers less than or equal to -21.
Absolute value is always a positive number so in this case the absolute value of -13 is 13 so you can say the temperature monday morning was a lot of 13° F
