Indeed it would!

**algebra**

You can do this a couple of ways. Since slope is rise/run, you can plot the points then count up or down then back or forth to determine slope. A method that always works is plug your points into this formula (hopefully I can write it so you understand:)) y (two) - y (one)/x (...

**math**

Look at it as 40% of what amount is $20. Percent/100 = is/of 40/100 = 20/x Multiply 20 by 100, then divide by 40 So, 2000 divided by 40 will give you your answer

**algebra**

You need 2 points on a line in order to determine slope.

**arithmetic**

Are you trying to figure out how much each person gets? If so, you don't care how many people are involved, just take the amount and divide by the number of people who will split it. 72/4

**Pre Algebra**

Just divide the cost by the number of cans purchased and you will have your answer.

**Pre Algebra**

12 + 4n = 6(n - 2) 12 + 4n = 6n - 12 +12 +12 24 + 4n = 6n - 4n -4n 24 = 2n solve for n and you've got your answer!

14900-1250-750=12900 m will be monthly payment 12,900 = 60m 215 = m

**algebra**

Area is l x w, so 400,000 x 500,000 is 200,000 and half of that is 100,000. If Kirk mows half of the 400 ft. width, then 1/2(400) is 200. If the mower mows a 5 ft. wide path, how many passes will Kirk need to make?

First of all, check you answer for number 1 and make sure it's correct. 3. You need two sheets that equal 1 1/8 in. or 9/8 inches. So, 1 in. and 1/8 in. = 1 1/8 7/8 in. and 1/4 (or 2/8) = 9/8 3/4 (or 6/8) and 3/8 = 9/8 1/2 (or 4/8) and 5/8 = 9/8 Okay, I gave you that part....

Basically, the number inside the / / is always positive. Only if it has a negative sign on the OUTSIDE, is it negative. The / / means "absolute value" which is simply how far away from 0 on a number line the number is. So, /-48/ is 48 spaces from 0, so it's value...

**ALGEBRA**

I think you may have forgotten one of the colors...yellow. There are 7 colors in the rainbow, so it would be 7! or 7x6x5x4x3x2x1 which would give you 5040.

Figure out the cost for the minutes then compare the two. The cell is .85 per minute times 65 minutes. The land line is .15 per minute times 65 minutes plus the $45 monthly fee for the total cost.

350 x 1.07 = ? If you do not understand why this is the equation, please let me know and I will explain.

**Math**

To turn a fraction into a decimal, take the denominator and slide it to the outside to make a division problem...in this case 1 divided by 5, which equals .20 To turn a decimal into a percent, move the decimal point 2 places to the right and add a percent sign. The 1 is a whol...

**Math**

It would be 1.2 because you can find percent by dividing the numerator by the denominator....just slide the bottom number in the fraction to the outside to make a division problem then divide. 1 divided by 5 is .2. You then must put your one back in front. Hope this makes sense.

**ALGEBRA**

Integers are positive or negative whole numbers, so they are all integers.

You are correct. O+ can receive only O+ or O-.

**math**

Just turn you percent into a decimal (move the decimal point 2 places to left) and multiply the two numbers together.

**geometry**

Work backward with what you know. The formula for circumference is 2*pi*r. Solve for this and you will have the radius. So, 2*3.14*r = 2368 6.28r = 2368 Divide both sides by 6.28. This will give you the radius. Just mulriply it by 2 and you will have the diameter. Hope this is...

**Math**

Conbine your positive and negatives then solve. positives are 7 and 6 = 13 negatives are -9 and -5 = -14 You now have 13 - 14 You can do it from here. In the second one, remember you have to have a common denominator to add or subtract fractions. Give that one a try!

**math**

Think of it as 20% of what is 360. Percent over 100 and is over of. So, 20/100 = 360/x 360 x 100 = 36000 Divide this by 20 and you will have your answer.

**Math**

How about just dividing by 2 in each step?

**math**

Since a pie chart represents 100%, I'd find the percentage for each and divide them up in your chart as close a possible. There are 40 total in your count, so 17 Army represents 42-43%, 10 Navy for 25%, and so on. I hope this helps:)

When turning a percent into a decimal, take the % sign off and move the decimal point 2 places to the left. So your 9% would be .09 Percents are based on 100, so to turn 9% into a fraction, just put it over 100. It would be 9/100. You must reduce it possible. I hope this is wh...
