The sum of 7-1 and 7-2 will be a rational number because sum of rational numbers is a rational numbers.
A rational number is a number which can be written in p/q form where q≠0.
We know that when two rational numbers is added then the sum is also a rational number. And when two rational numbers are subtracted then the difference is also a rational number.
So in the given question, lets study the term differently that is,
i) 7 - 1 is a rational number because their difference is equal to 6 and it can be written in p/q form which is 6/1.
ii) 7 – 2 is also a rational number as their difference will be 5 which is a rational and can be written in p/q form which is 5/1.
So when these two rational numbers are added their sum will also be a rational number which is 11.

Answer: Part A - 113°
Step-by-step explanation:
A. 6x-5 = 5x+7 -> x = 12
6x-5 -> 6(12)-5 = 72-5 = 67
180-67 = 113
4 4/7 feet is it's simplest form because 20 I'm chea equal 1.67 feet and 7 feet equals 84 inches so do 20 × 4 = 80 then you would have 4 left over and turn that into 4/7

Answer:
<em>The expression that represents her gross pay each day will be: 
dollars.</em>
Step-by-step explanation:
Suppose, Harriet's gross pay each day 
So, her total gross pay for 7 work days 
Given that, her gross pay at the end of 7 work days is 
dollars.
So, the equation will be.......
Thus, the expression that represents her gross pay each day will be: dollars.
