\displaystyle 3w+9-6r

Step-by-step explanation:

Distributive property: A(B+C)=AB+AC

<em>Group like terms.</em>

<em>\displaystyle-5r-r+3w+7+2</em>

<em>Add the numbers from left to right.</em>

<em>\displaystyle-5r-r=-6r</em>

<em>\displaystyle -6r+3w+7+2</em>

<em>Finally, add the numbers from left to right, to find the answer.</em>

<em>2+7=9</em>

<em>\displaystyle 3w+9-6r, is the correct answer.</em>

Two workers finished a job in 12 days. How long would it take each worker to do the job by himself if one of the workers needs 1
Lorico [155]

Two workers finished a job in 7.5 days.

How long would it take each worker to do the job by himself if one of the workers needs 8 more days to finish the job than the other worker?

let t = time required by one worker to complete the job alone

then

(t+8) = time required by the other worker (shirker)

let the completed job = 1

A typical shared work equation

7.5%2Ft + 7.5%2F%28%28t%2B8%29%29 = 1

multiply by t(t+8), cancel the denominators, and you have

7.5(t+8) + 7.5t = t(t+8)

7.5t + 60 + 7.5t = t^2 + 8t

15t + 60 = t^2 + 8t

form a quadratic equation on the right

0 = t^2 + 8t - 15t - 60

t^2 - 7t - 60 = 0

Factor easily to

(t-12) (t+5) = 0

the positive solution is all we want here

t = 12 days, the first guy working alone

then

the shirker would struggle thru the job in 20 days.
