Step-by-step explanation:
Ok, the perimeter of the rectangle is 40 inches.
5/6 hour = 5/6 × 60 = 300/6 = 50 minutes
8 tasks in 50 minutes
1 task = 50/8 = 6 1/4 minutes
a. robot completes task in 6 1/4 minutes
b. #tasks per hour =
#of tasks × time takes to do task < or = 60
n × 6.25 = 60
6.25n = 60.
n= 60/6.25 = 9.6
robot can complete 9 tasks in one hour
It’s b i believe, if i did the math correctly
Jenny is 3 less than half of a, or 1/2a - 3. Fraz is twice a + 7, or 2a+7.
