N= height of window
n+3 = width of window

2 (n+n+3) =38  (2 times the sum of the two different sides is the same as the perimeter)

2(2n+3) = 38  
4n+6 = 38    (I combined like terms)
4n = 32 = (I subtracted 6 from both sides of the equation)
n=8  (I divided both sides by 4)
n=8 and n+3 = 11

Check  If the two sides are 8 and 11 then 1/2 way around the rectangle is 8+11=19 and all the way around is twice that or 38.

A company has two large computers. The slower computer can send all the company's email in minutes. The faster computer can comp
postnew [5]

Both the computers will take 18 minutes to do the job together.

The slower computer sends all the company's email in 45 minutes.

The faster computer completes the same job in 30 minutes.

Let's take minutes t  to complete the task together.

As they complete one job, we get the following equation:

\frac{t}{45}+\frac{t}{30}=1

LCM of 45 and 30 is:

45 = 3 x 3 x 5

30 = 2 x 3 x 5

LCM = 2 x 3 x 3 x 5 = 90

Now, solving for t;

⇒\frac{2t+3t}{90} = 1\\\frac{5t}{90} =1\\5t=90\\

Dividing both sides by 5;

\frac{5t}{5}=\frac{90}{5}

We get t = 18

Hence, it will take both the computers 18 minutes to do the job together.

A company has two large computers. The slower computer can send all the company's emails in 45 minutes. The faster computer can complete the same job in 30 minutes. If both computers are working together, how long will it take them to do the job?
