Answer:
6 6/9
Step-by-step explanation:
A real number is very broad. Real numbers consist of;
- Rational Numbers
- Integers
- Whole Numbers
- Natural Numbers
- Irrational Numbers
Knowing this, 6 6/9, and many more real numbers are between 6 4/9 and 6 8/9.
Steps:
let “x” be number of hrs
let “y” be total cost
Abe:
50x + 75 = y
Plumbing Service:
65x=y
Since both equations are equal to y, you can set them equal to each other.
65x = 50x + 75
isolate for x:
65x - 50x = 75
15x = 75
x = 5
therefore it will take 5 hours for each to cost the same. you should call Abe for any task more than 5 hours because it will be cheaper and you should call the Plumbing Service for any task less than 5 hours because it will be cheaper.
Answer:
x+y=11
Step-by-step explanation:
take the square root of both sides.
(x-7) + (y+3) = 7
collect like terms
x+y = 7+7-3
What you would do is add 25in^2 and 36in^2 together to get your answer. thanks for asking a question I could answer.
