Answer:

3x+5y

Step-by-step explanation:

Subtract (6x-3y) from (9x+2y):

(9x+2y)-(6x-3y)

This can also be seen as:

(9x+2y)-1(6x-3y)

Distribute the -1 to (6x-3y):

(9x+2y)-1(6x)-1(-3y)\\\\(9x+2y)-6x+3y

Simplify the parentheses:

9x+2y-6x+3y

Group like terms:

(9x-6x)+(2y+3y)

Combine:

3x+5y

This expression can't be further simplified. Therefore, 3x+5y is the answer.

:Done

Jim was thinking of a number. Jim adds 20 to it, then doubles it and gets an answer of 99.2. What was the original number?
azamat

Alright, lets get started.

Jim was thinking of a number.

Suppose the number Jim was thinking, is x.

Jim adds 20 to it means number will be = x+20

And Jim doubles it, means 2*(x+20)

Jim gets 99.2 and as per us, he gets 2*(x+20)

So, making them equal

2(x+20)=99.2

2x+40=99.2

Subtracting 40 in both sides

2x+40-40=99.2-40

2x=59.2

x=29.6

It means the original number is 29.6.   :   Answer

Hope it will help :)

The manufacturer of a laser printer reports the mean number of pages a cartridge will print before it needs replacing is 12,425.
snow_lady [41]

A suitable probability app shows the 1st percentile to be at about 11040 pages.

_____

The app shown has an error in the first decimal digit. The number is closer to 11040.82301. We expect the manufacturer would round to the nearest 10 or 50 or 100 in advertising.
