Just divide 75 by 9 multiplying 100 gives u the answer. And same for the rest
When 'c' is negative both p and q would have the same sign and when opposite signs whereas when b is positive and negative, both would have positive and negative signs respectively.
<h3>How the signs affect the factored form</h3>
The ways in which the signs of 'b' and 'c' affect the form include;
- if c is negative, then p and q have opposite signs.
- If c is positive, then p and q have the same signs.
- If b is negative, both the signs of p and q would be negative.
- Also, if b is positive, then the signs of both p and q would be positive.

Answer: Jordan worked for 10 hours and Sydney worked for 6 hours.
Step-by-step explanation:
Let x represent the number of hours
that Jordan worked.
Let x represent the number of hours that Sydney worked.
Jordan can iron 20 shirts per hour, and Sydney can iron 25 shirts per hour. They ironed 350 shirts between them. It means that
20x + 25y = 350- - - - - - - - - - - 1
Jordan worked 4 more hours than Sydney. It means that
x = y + 4
Substituting x = y + 4 into equation 1, it becomes
20(y + 4) + 25y = 350
20y + 80 + 25y = 350
20y + 25y = 350 - 80
45y = 270
y = 270/45
y = 6
x = y + 4 = 6 + 4
x = 10
The answer is C. $910, all you do is take the income and divide it by the number of months to find the average.
