Fred washes a car in 6 minutes, carl washes a car in 8 minutes. if they wash a car together then how long will it take?

Based on the problem Carl will complete...

1/6 of the job per minute.

Fred will complete 1/8 of the job per minute.

Together they will complete... 1/6+1/8 of the job per minute.

That would be 7/24.

How long will that take?

1/(7/24)=24/7=3 3/7

It will take 3 and 3/7 minutes to finish washing the car.

3.5 minutes.

Step-by-step explanation:

If Fred can wash 1/6 of a car in 1 minute and Carl can was 1/8 of a car in a minute as well then together in 1 minute it would be:

= 1/6 + 1/8

= 4/24 + 3/24

= 7/24

=

= 3.429

So we have:

≈ 3.5 min

I hope this helps!

then say something, tell them they won’t respect you if you don’t even have respect for your self sweetheart you need to lay it on them, all of it : )

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
