Hey there!
When we subtract a negative, we're doing the same as adding because you're taking away negatives, and you're doing the opposite of subtracting- adding/
Therefore, we have:
-5 + 8
Now, we can think of a number line.
If we have -5 and go 8 to the right because we're adding and getting closer to 0, we'd actually get positive 3 because you'd be going past 0 and into the positives.
Therefore, the answer is positive :)
Hope this helps!
Answer:
12x+15y
Step-by-step explanation:
The equation would be
letter b. 25h + 20 (15 - h) = 350
Let’s try to solve to get the value of h
=> 25h + 20(15 -h) = 350
=> 25h + (300 – 20h) = 350
=> 25h + 300 – 20h = 350
=> 300 + 5h = 350
=> 5h = 350 – 300
=> 5h / 5 = 50/ 5
=> h = 10
Thus the value of h is 10 which means a car travel on the highways and
used 10 gallons of gasoline,
(x+2)(x-8) you got to find the factors of 16 and they have to add up to -8
