Answer:
C) -3x=-3
Step-by-step explanation:
When you subtract the 3x-y=7 from 6x-y=10, you will receive the following equation:
3x-6x-y-(-y)=7-10
-3x-y+y=-3
-3x=-3
As we can see, this equation matches the one in option C, meaning that it's our answer!
Answer:
77 degrees and 90 degrees
The angle d is shown as 90 by the perfect right angle. The angle e has to equal 180 when added to f. So 180-103=77.

$5 each teenager
Step-by-step explanation:
divide 75 by 15

Step-by-step explanation:
Using absolute value to tell wether the sum of two integers is positive or negative.
Suppose we have a positive integer,
x and a negative interger, -x and we want to find their sum, we take the absolute values of each of the integers, that is |x| and |-x|. Then we subtract these values: |x| - |-x|. If the larger integer is positive, the result of the difference is positive, but if the larger number is negative, the result of the difference is negative.
For any integer x, x + (-x) = 0
