It would be 20 hrs because if you put them both in an equation aka y=25x+100 and y=30x just plug in numbers into the x until they both have the answer which in this case is 20
Answer:
-11x +3y + 25
Step-by-step explanation:
7-8x+4y+18-3x-y
= -8x-3x +4y-y +18+7 (putting like terms together)
= -11x +3y + 25 (Adding like terms)
