You know the following information:

1. The amount of money (in dollars) earned last year was:

2,247,852,199

2. The amount of money (in dollars) earned this year, is:

3,000,962,245

Then, to estimate the sum (the total amount of money the Software Company earned in those two years, you can round the numbers to the nearest billion.

Having:

2,247,852,199

You need to look at the digit located in the Hundred millions place. Notice that this is:

2

Then, since:

2

You need can't round up. Then:

2,247,852,199\approx2,000,000,000

Now, having:

3,000,962,245

You can identify that the digit in the Hundred millions place is

0

Therefore:

3,000,962,245\approx3,000,000,000

Now you can add the numbers rounded:

2,000,000,000+3,000,000,000=5,000,000,000

Hence, the answer is: Option B.

Prove that at a party where some people shake hands, the number of people who shake hands with an odd number of people is an eve
Kobotan [32]
If there are n people, each person could shake hands with 0 people, 1 person, 2 people,... on up to shaking hands with n − 1
people. Count how many different answers there are to asking the person the question "How many hands did you shake?" How many people are there? If the people are the pigeons, and the possible answers to the question "how many hands did you shake" are the holes, can we conclude anything yet? No? How about now noticing that at least one of the holes "I shook hands with noone" or "I shook hands with everyone" has to be empty... now what?

"Since there are more pigeons than holes there must be a hole with at least two pigeons in the same hole" Now, replace the word "pigeons" and "holes" with the appropriate terms for the context of your specific question, remember we are talking about people and number of handshakes they participated in.

X + 2 = 5x + 26<br><br> Please help
kkurt [141]
x+2=5x+26

Move all the x's to one side of the equation. This is a step necessary to solve this equation.

Subtract both sides by x.

x+2-x=5x+26-x
2=4x+26

Flip equation. We always want to have the variable written on the left side.

4x+26=2

Subtract both sides by 26.

4x+26-26=2-26
4x=-24

Divide both sides by 4 to finish this off.

x=-6

That's your answer. Have an awesome day! :)
