Answer:
3x + 8y = 72
19x + y = 72
Step-by-step explanation:
dubbles = x
mimstoons = y
Standard form:
Ax + By = C
3x + 8y = 72
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
