Answer:
x = 10
Step-by-step explanation:
You can compare parts of each expression to see that x in the left-side expression is replaced by 10 in the right-side expression.
x = 10
__
If you'd rather, you can work your way down to the same conclusion by undoing the operations that have been done to x.
(6x -1)° = (6(10) -1)° . . . . . . given
6x -1 = 6(10) -1 . . . . . . . . . divide both sides by °
6x = 6(10) . . . . . . . . . . . . add 1 to both sides
x = 10 . . . . . . . . . . . . . . . . divide both sides by 6
It’s 81 but I just needed to answer a question
Answer:
7. Option B:40 is the correct answer.
8. Option D: y = 40x+75 is the correct answer.
Step-by-step explanation:
Given that:
Charges per hour = $40
Fee charged by repairman = $75
x = number of hours
y = total fee
According to given statement;
y = 40x+75
The standard equation is
y = mx + b
On comparing;
Slope of the line is given by m, therefore
Slope = m = 40
Hence,
7. Option B:40 is the correct answer.
8. Option D: y = 40x+75 is the correct answer.
