Answer:
c. 30.0 minutes
Step-by-step explanation:
Max mows 1/45 lawns per minute.
Jan takes twice as long (90 minutes per lawn), so mows 1/90 lawns per minute.
Working together, they mow ...
(1/45 + 1/90) lawns per minute = (2/90 +1/90) lawn/min = 3/90 lawn/min
= 1/30 lawn/min
Then for one lawn, it takes ...
(1 lawn)/(1/30 lawn/min) = 30 min

Answer: 3
Step-by-step explanation:
Let the smaller number be y.
Since the difference of two numbers is 5,then the larger number will be: y+5
The sum of three times the larger number and twice the smaller number is 30. This can be written as:
3(y+5) + 2y = 30
3y + 15 + 2y = 30
5y + 15 = 30
5y = 30 - 15
5y = 15
y = 15/5
y = 3
The smaller number is 3
