Martha can paint a room in 2 hours. jamie can paint the same room in 6 hours. how long, to the nearest tenth of an hour, will it take them to paint the room together?

It will take 1.5 hours to paint the room together

Step-by-step explanation:

Martha can paint a room in 2 hours. Jamie can paint the same room in 6 hours.

Work done by Martha in 1 hour =

Work done by Jamie in 1 hour =

Work one together in 1 hour =  

Now take common denominator to add both fractions

LCD = 6, Multiply the first fraction by 3

Now add the numerators

To find total hours of painting together, we take reciprocal of 2/3

Time taken to paint together =

It will take 1.5 hours to paint the room together

The nearest tenth of an hour, will it take them to paint the room together is 1.5 hours.

Given data:

Time taken by Martha to paint a room is, 2 hours.

Time taken by Jamie to pain the same room is, 6 hours.

Then work done by each of Martha and Jamie in 1 hour is given as,

Total work done in 1 hour is given as,

To find total hours of painting together, we take reciprocal of 2/3.

Then, time taken to paint together is, 3/2 = 1.5 hours.

Thus, we can conclude in the nearest tenth of an hour, will it take them to paint the room together is 1.5 hours.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
