Answer:

Words type in 13 minutes are 975 words .

Step-by-step explanation:

As given

Charles can type 675 words in 9 minutes.

Thus

Words\ type\ in\ one\ minutes = \frac{Total\ number\ of\ words}{Total\ time}

Put all the values in the above

Words\ type\ in\ one\ minutes = \frac{675}{9}

Words type in one minutes = 75 words

Thus

Words type in 13 minutes = 13 × Words type in one minutes

                                          = 13 × 75

                                          = 975 words

Therefore words type in 13 minutes are 975 words .

Answer:

1010

Step-by-step explanation:

There are a whole class of questions that rely on the method to this one.

First add up what you know

1270 + 1150 + 870 + 1450 = 4740

Now add on the 5th month (which you don't know. Call it x)

4740 + x

Divide by 5

(4740 + x)/5 = 1150 and that is your equation    

Solution

Multiply both sides by 5

5*(4740 + x) / 5 = 1150 * 5

4740 + x = 5750

Subtract 4740 from both sides

4740 - 4740 + x = 5750 - 4740

x = 1010

Which seems kind of low, but that's what the numbers come to.
