Answer: Choice B</h3>
Doug borrowed $2 from his friend every day from Monday through Friday. How much money does Doug owe in all?
==============================================================
Explanation:
The notation 5(-2) is the same as saying "5 times negative 2"
The negative represents the amount of debt that Doug goes into when borrowing that $2. When borrowing the same amount over the course of 5 days, he'll be in debt a total of 10 dollars. So we'd write -10 to represent this.
You could also write it out the longer way
-2 + (-2) + (-2) + (-2) + (-2) = -10
There are five copies of "-2" being added up to arrive at -10
Though it's much simpler to say
5(-2) = -10

Answer:
x = -7
Step-by-step explanation:
4(1 - x) + 2x = -3 (x + 1)
4 - 4x + 2x = - 3x - 3
- 4x + 2x + 3x = - 3 - 4
x = -7
Answer:
300 kilometers per hour
Step-by-step explanation:
300 kilometers x 1 hour = 300 kilometers/hour
6x + 5 = 5x + 8 + 2x
6x + 5 = 7x + 8
-5 -5
6x = 7x + 3
-7x -7x
-1x = 3
/-1 /-1
x = -3
