It's not a number sentence because it doesn't have the answer. Ms. Sue wrote the full number sentence out for you.

It's identity. That was one of your choices, you spelled it wrong.

What Daniel said, and then divide that by 4.

You can diagram the array for 4 x 30 and 4 x 6 and then add them together.

Whole numbers mean don't use a fraction!

Thanks MathMate.

Please imagine a triangle here. >.< the 'o' is a person and the two peaks are the mountains. /\___/\ _\___/ ___o Explain why the distance between these two peaks are greater than the difference of the distances from the person to each peak.

So it does not obey the law of inertia?

Does an object moving in a circle obey the law of inertia? Which way would it move if there were no net force on it?

math correct or not?
Yes for both. Good job.

A much easier way to do this would be: 1) x+y=1300 2) x+2z=1400 3) x+y+z=1600 Look at 1 and 2. Since x+y=1300 and x+y+z=1600, z obviously equals 300. Now substitute that back in #2. x+2(300)=1400, x+600=1400, x=800. Now substitute x and z back in #3. x+y+z=1600, 800+y+300=1600...

What are your choices? Did you look up the word "oligopoly"?

11x+8y=103 (1) 22x-7y=68 (2) Multiply (1) by -2 to cancel the x's -22-16y=-206 (3) 22x-7y=68 (2) Add them together. -23y=-138 Divide by -23 y=6 Now substitute y=6 into either equation (1) or (2) to solve for x. Post your work and answer if you'd like it checked.

Radical 10, please don't repost questions! I took the time to solve this for you when it was already done.

You just plug them in and see if both are true. If they are, it is a solution. -(6)-8(2)=-22 -7(6)+3(2)=-36

Try this one using the steps in the problem I did for you as a guide.

7-7/2x=-5 -7/2x=-12 Multiply both sides by -2/7 x=3 3/7

-10-(-10) Two negatives become a positive so -10+10= ?

What?

Yes, because they can both be divided by 5. Divide the numerator by 5 and that's your new numerator. Divide the denominator by 5 and that's your new denominator.

You typed something wrong. Please fix your third sentences.

x+y=3742 x=y-44 y-44+y=3742 2y-44=3742 2y=3786 y=1893 Now plug that back into either of the first two equations to solve for x.

The hypotenuse is always the longest side and across from the right angle. So which letter does that match up with?

No, the directions said to round to the nearest tenth. 6.122 rounded to the nearest tenth is 6.1.

5 is right. (Still not sure about 9. Stuck between C and D.)

None of them are equal to -1. Please check your signs and post again. All of the answers will be positive.

Try again on these: 1. It's asking what Juan is like. 5. Look up how you say Si, me gusta and no me gusta in a sentence. 8 is correct. I think 9 is also correct but I'm not 100% positive on that one.

You already asked this question. Have you read the book? I already know the answer from just reading the wikipedia page about it.

Putting this information into the exponential growth formula gets you the equation y=100(2^x) where x equals the number of hours. Plugging in 12 for x, you get 409600.

No, move the decimal 2 places to the right.

It's not 6, Renee. You have to solve for x in the equation I made for you. (8+5+10+3+x)/5=6 (26+x)/5=6 26+x=30 x=?

Five Number Summary
(8+5+10+3+x)/5 = 6

College Algebra
Agreed, Kelly. Good for you. I think what Reiny was getting at is at the origin the point is (0,0) so it is possible. Not 100% positive though.

Why do you have to make degrading comments all the time? Either help or don't.

x+4y=-16 (1) 3x+2y=12 (2) Multiply (1) by -3 to get the x's to cancel -3x-12y=48 (3) 3x+2y=12 (2) Now add (3) and (2) together. -10y=60 Divide by -10. y=-6 Substitude y=-6 into equation (1) or (2) to solve for x.

L=laser tag, V=video games 3L+5V=17 (1) 4L+7V=23 (2) Since the question asks only about the video games, we want to eliminate the L's. We can do this by multiplying the first equation by 4 and the second equation by -3. 12L+20V=68 (3) -12L-21V=-69 (4) Add 3 and 4 together....

Get out a calcutor and do 1/8, then move the decimal two places to the right and put a percent sign after that number.

math
3x+4=5x-7 You want to get the x's on one side and numbers on the other. First, subtract 3x from both sides. 4=2x-7 Now add 7 to both sides. 11=2x Divide both sides by 2. 11/2=x 5 1/2=x

They are both right. The easiest way to do this is to make a proportion, though. 2.5/30=x/120, Cross multiply 30x=300, solve for x.

You cannot simplify this.

Do you understand, Bridgett? You just multiply that number through 1. Examples: 8!=8*7*6*5*4*3*2*1, 3!=3*2*1, 12!=12*11*10*9*8*7*6*5*4*3*2*1.
