Question about Microsoft Windows XP Professional

Ad

Check my work, to make sure that I did it correctly:

X + Y = 60 and 2 * X - Y = 82.5

2 * X + 2 * Y = 2 * 60 and 2 * X - Y = 82.5

2 * X + 2 * Y - 2 * X - (-Y) = 2 * 60 - 82.5

2 * X - 2 * X + 2 * Y + Y = 46.5

3 * Y = 46.5

Y = 15.5

QED. :-)

60 - 20 = 40

40 / 20 = 2

Answer check: (2*20)+20=60 (40)+20=60 The numbers are 40 and 20.

40 / 20 = 2

Answer check: (2*20)+20=60 (40)+20=60 The numbers are 40 and 20.

The two numbers are 32 and 34. The rest is your homework, you do it.

You enter the problem into the calculator and when you are finished you press the equals sign to make it give you the answer to your problem.

Here is an example;

If I wanted to know what the sum (or total) was for 2 + 10+ 16 - I would enter the number 2 and then the plus sign + and then the number ten and the plus sign + and then the number sixteen and the plus sign again + and then press the equals sign which looks like this =. when I press the equals sign = the calculator gives me the answer to my question of what the total of those numbers are.

I hope this helps?

Assume this:

A is the greater number

B is the lesser

You have 2 equations

A + B = 20

A = 3xB - 4

Substitute the solution for the second eqation into the first

(3xB - 4 ) + B = 20

solve for B

3xB + B = 20 + 4

4xB = 24

B = 6

solve for A with solution for B

go back to equation 2

A = 3xB - 4

A = 3x6 - 4

A = 14

So A = 14

and B = 6

Otherwise use trial and error.

Hope that helps.

Do you need help doing your homework?

If so, here's a first attempt. It may be correct, and it may not be.

It's up to you to understand the process, and to make any needed corrections.

X minus 11 equals Y.

So, X is larger than Y.

So, 3 times X minus 33 equals 3 times Y.

Thus 3 times X equals 3 times Y plus 33.

Also, 3 times X minus 4 equals 4 times Y.

So, (3 times Y plus 33) minus 4 equals 4 times Y.

Thus 0 times Y plus 29 equals 1 times Y.

So, Y equals -27.

Pay more attention in math class, do your daily homework or tutorials. If you do not understand the chapter or any math problems, just ask the math teacher directly. He or she is the best bet that can help you directly dealing with your situation.

Just don't forget "In any examinations, it is a test of what you don't know".

press the plus key again, it should work. ie put a number in and press the plus key twice, it should double, and again it should double again and so on
