Step-by-step explanation:
We want to subtract 8x + 3 from -2x+5. We can create an expression to represent this.
-2x + 5 - (8x + 3).
After this, lets distribute the - sign (think of this like expanding something with -1).
-2x + 5 - 8x - 3
Lastly, we just need to combine like terms.
-2x + 5 - 8x - 3
Combine the 5 and -3 to get 2.
-2x + 2 - 8x
Combine the -2x and -8x to get -10x.
-10x + 2
The final answer to the question is therefore A.
Well, you know that the sum of those two numbers aren't zero, as they aren't additive inverses of each other. The sum of these numbers will, furthermore, take the sign of the "greater" number without its sign. For example, 2-3 would be negative, since the negative sign of "3" is of the greater number without its sign.
Let e = your earnings.
Let h = number of hours you work.
Since you earn $20 per hour, the amount you earn is the number of hours times $20, or 20h.
e = 20h
