If Sadie earns $11.25 per hour, her earnings will vary directly with the number of hours that she has worked per week.
If she made $146.25 in a work week, she worked 13 hours.
13 hours x 11.25 = 146.25

Answer:
option 3 , -5
Step-by-step explanation:
0.6(10n +25) = 10 + 5n
==> distribute the 0.6
6n + 15 = 10 + 5n
==> subtract 5n from both sides
n + 15 = 10
==> subtract 15 from both sides
n = -5
Answer:
x = 3 . . . or . . . x = 4
Step-by-step explanation:
The factored form is ...
(x -3)(x -4) = 0
The zero product rule tells you the solutions are the values of x that make the factors be zero:
x = 3
x = 4

Comment on factoring
When the leading coefficient is 1, the coefficient of the x-term is the sum of the constants in the binomial factors, and the constant term is their product. You can see this by multiplying out the generic case:
(x +a)(x +b) = x^2 +(a+b)x + ab
What this means is that when you're factoring, you're looking for factors of the constant that add up to give the coefficient of the x-term. Here, the x-term is negative and the constant is positive, so both factors will be negative.
12 = -1×-12 = -2×-6 = -3×-4
The sums of these factor pairs are -13, -8, -7. Clearly, the last pair of factors of 12 will be useful to us, since that sum is -7. So, the binomial factors of our equation are ...
(x -3)(x -4) = 0
___
If the leading coefficient is not zero, the method of factoring is similar, but slightly different. Numerous videos and web sites discuss the method(s).
