Answer:

Step-by-step explanation:
The inequality that can be used to determine h is shown below:-
As per the given situation, it is mentioned that a plumber could earns $50 for a repair job, so for three jobs he earned $150 as a total amount
Now
We presume h be the number of hours
Also he earns additional $75 per hour worked so $75
Total amount is $150 + $75h)
The total amount is more than $600
So, the inequality equation is as given below:

He walked the same distance to school and back home.
I hope this helped! :-)
X=10 Y=-2 Z=4 so basically your answer will be (10,-2,4) & your welcome
here, x = 2
putting the value of x in the equation we get:
6x-7y=-9
or, 6×2- 7×y=-9
or, 12- 7×y= -9
or, 7×y =-21
so, y = -3
The square root of 121 is 11 because 11 times 11 is 121.
