Answers
Answer:
A.)
Step-by-step explanation:
The answer that you had chosen is correct, because the number line is stating that you are subtracting 5 from 0, giving you -5. Then it is saying that you are subtracting 2 from that, giving you -7.
B.) is wrong, because they are adding the answer of the correct equation with another number, which would equal -12.
C.) is incorrect, because when you are adding a positive with a negative, you are actually subtracting, not adding. When you are doing this, always keep the sign for the answer (negative or positive) with whatever the larger addend is. So in this letter's situation, the equation would look like this: -5 + 2 = -3.
D.) is incorrect because once again, they are taking the original correct answer and subtracting it from another number, which would be -12.
I hope this helps.

Answer:
x=3
y=4

By moving x to the right-hand side of the first equation we get y=-x+7, which we then substitute for y in the second equation. Solving gives x=3, which we can then put into the first equation and get y=4.
Marco owed his father $250 and began paying him back $20 at the end of each week, beginning November 1st. Joni owed her father $150 and began paying back $10 at the end of each week, beginning on the same day. What Marco owed his father in dollars at the end if n weeks can be represented by f(n) = 250 - 20n. What Joni owed her father in dollars at the end of n weeks can be represented by g(n) = 150 - 10n.
Answers
so we get
150 - 20n = 130 - 15n
Now n gives us the number of weeks so solve for n
20n - 15n = 150 - 130
5n = 20
n = 4
Now check your solution
150-20(4) = 70
130 - 15(4) = 70
So our answer checks out after 4 weeks both girls who their dads the same amount of money .

I need help fast what is 9m−(3+7m) simplified?
Answers
Answer:
Simplifying 9m + -3 + -7m = 0
Reorder the terms: -3 + 9m + -7m = 0
Combine like terms: 9m + -7m = 2m -3 + 2m = 0 Solving -3 + 2m = 0
Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right.
Add '3' to each side of the equation. -3 + 3 + 2m = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 2m = 0 + 3 2m = 0 + 3 Combine like terms: 0 + 3 = 3 2m = 3
Divide each side by '2'. m = 1.5
