Answer:
36(z + 2)
Step-by-step explanation:
First, find the GCF or greatest common factor. The GCF is the largest factor that all the numbers share. Both 72 and 36 are divisible by 36. 72 ÷ 36 = 2 and 36 ÷ 36 = 1. So, the factoring would look like 36(1z + 2) or 36 (z + 2)
10/45 - 9/45 is what i would think someone can fact check though.
Adam's average speed = 40 miles per hr
time for the trip = 30 minutes = 0.5 hrs
Distance travelled by adam = speed * time = 40 * 0.5 = 20 miles
Distance travelled by Beth is 5 miles longer means 20 + 5 = 25 miles
Time took by Beth is 20 minutes more means = 30 + 20 = 50 minutes = 0.83 hrs
Average speed of Beth = distance / time = 25 / 0.8333
Average speed of Beth = 30 miles : Answer
Hope it will help :)
Answer:
-2/3c + 8
Step-by-step explanation:
-2/3 (c-12) distribute (multiply) the -2/3 to everything in the parentheses.
-2/3 * c = -2/3c
-2/3 * -12 = 24/3 which simplifies to 8 (negative times a negative = positive)
-2/3c + 8 is your answer
