Amachine can fill a box with twenty pencils in 30 seconds. how many boxes can the machine fill in 2 hours?

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x

b=-6

compare the slopes

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
