Answer:
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
10*y-(80)=0
Pull out like factors :
10y - 80 = 10 • (y - 8)
Solve : 10 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solve : y-8 = 0
Add 8 to both sides of the equation :
y = 8
Answer:
x = 19
Step-by-step explanation:
The work shown is almost complete. It can be finished by multiplying both sides of the equation by the inverse of the coefficient of x.
x-coefficient: -1/3
inverse of x-coefficient = 1/(-1/3) = -3
Then you have ...

Short answer: 0.69Take 100. 31% = 31, 100-31=69Of course, when you increase the result by 31 percent you do not get the 100 back. But that was not the question.But, for completeness what do I multiply by to get the number, when adding 31 percent, gives me the original number, it is 0.7633 (1/1.31)

Your measure start at 16. So that is the basis (unless stated otherwise) upon which you reference the change.
That is:

This gives:

For this to be a percentage we need the denominator such that it becomes 100. Thus we have:

Step-by-step explanation:
Let
x -----> the number of hours that the painter works
we know that
The inequality that represented this situation is equal to
solve for x
Subtract 60 both sides
Divide by 15 both sides
The maximum number of hours is 2
