Could you word this better? Would love to help you out, but I'm not sure what the details for the question are.
Answer:
Billy used 28 mins 30 sec to mow the lawn and Bobby used 43 mins 30 sec to now the lawn both within 72 mins
Step-by-step explanation:
let x represent Billy
let x+15 represent Bobby
x + x + 15 = 72
2x = 72 - 15
2x = 57
2x/2 = 57/2
x = 28.5 minutes = 28 minutes 30 seconds
Bobby = x + 15
= 28.5 + 15
= 43.5 minutes= 43 minutes 30 seconds
Add 23 from both sides
6f = 18
F= 3
6(3)-23
= 18-23
=-5
Believe me
Answer:
42
Step-by-step explanation:
8+8+12+4+4+3+3
Something like this for the problem.
Do a proportion
40/100= 8/x
8 x 100= 800
Cross multiply and divide
800 divided by 40= 20
So answer is 20
