**Math**

PLEASE HELP ME FACTOR COMPLETLEY. 25w^2-144

**Math**

5 is correct. I don't think there is another answer.

**algebra**

use the quadratic formula to solve the equation 2x^2-3x=-6

**spelling**

I am proficient at _____________. Fill in the blanks with something you are proficient at. Look up the meaning in the dictionary if you are unsure of the meaning.

**math**

Or 25x2=50, count the zeroes (1), and put it on the end, 500

**science**

What's your question?

**math**

No need for an apology, George. I was simply saying that it's not the best method. :)

**math**

You do NOT want to attempt this problem by trial and error.

**math**

x+y=7 4.5x+6.5y=39.5 Multiply the top equation by -4.5 to cancel the x's: -4.5x-4.5y=-31.5 4.5x+6.5y=39.5 2y=8 y=4 Put that back in the first equation to solve for x.

**math**

If 100% of 7 is 7, what would 200% be? (Double it.)

**math**

10(3)+3=?

**algebra**

-20(7)=?

**algebra 8..helppp**

Yes, 15 credit hours per semester.

**Maath**

5x+7=32 5x=25 x=5 Graph x=5 by shading a circle at that point.

**math**

Go backwards and do the opposite. (9x8)=x x-18=y y/3 = z

**algebra**

(multiplying the second equation by -5 to cancel the y's) 9x+5y=-42 10x-5y=-110 19x=-152 x=-8 Put that in either ORIGINAL equation to solve for y, and then your ordered pair would be (-8, y), replacing y with whatever you get for y.

**chemistry**

if the mass of a 12.5 mL sample is 50.0 g, calculate the density of the sample I got 0.25 is that correct

**Geometry**

5x=3x+4 Subtract 3x from both sides. Divide both sides by 2.

**college**

What is the "action"? What is somebody doing?

**algebra 8th**

Yes it's -19/40. I didn't see that post of yours until now.

**algebra 8th**

16/40 and 35/40 is right. 16/40-35/40=? Do 16-35, use a calculator if you need to. That's your numerator (top number of a fraction). The 40 is your denominator (bottom number).

**algebra 8th**

What's your new denominator and fractions?

**algebra 8th**

Do you know how to find the common denominator and change both fractions?

**algebra 8th**

Right. The two negative signs makes a postive sign and they cancel out and equal 0. Good job.

**math**

-2y-11=-12 +11 +11 -2y=-1 /-2 /-2 y=1/2

**math**

Do the parenthesis first. (12)(11)=?

**algebra 8th**

5.2-2.5, Make sure to have it lined up, "borrow" and make the 2 a 12 and 5 a 4, 12-5=7, bring down your decimal, 4-2=2. The answer is 2.7.

**Spanish**

Please post your answers, and someone will check them for you.

**math**

Anything between 1,543,001 and 1,543,999..

**5th grade**

1/6h=9 Multiply both sides by 6. h=9 x 6

**math**

7+15=?

**correction**

If there's no parenthesis, you do it from left to right, and your answer would be 28. (4x5)+8=20+8=28

**Critical Thinking**

B isn't a claim.

**Algebra 2**

Glen/Taegan, stop switching names.

**english**

B is correct. Always replace with pronouns and that makes it easier to see. The garden club = they, and you would say they have, so it's correct.

**spanish**

clase.

**science**

And Pam/Ant, stop changing names. We don't mind when you post more than one question.

**science**

My guess would be a tropical savanna. Look it up for more information to check me.

**Algebra 1**

a^2+b^2=c^2 13^2+9^2=c^2 169+81=c^2 250=c^2 Take the square root of 250 for your answer.

**Probability**

I think it's 1/2, since you already know one is a boy for sure.

**social studies**

Correct.

**6th grade English**

Good job.

**Algebra 1**

15-13 3/8= 1 5/8 or 13/8 (13/8)/(3/4)=?

**math**

What about the 2?

**Math**

(x-4)(x-4)=20 x^2-8x+16=20 x^2-8x-4=0 Now use the quadratic formula.

**Math**

Line AT or TA

**algebra1**

I was thinking of it as 16/3. No need to get smart with me, Reiny.

**algebra1**

Divide them each out. I'll do the first one for you. 3/16=5 1/3=5.33 (line over the 3, it's repeating)

**algebra1**

Candace is correct.

**algebra1**

Try plugging in these numbers for each of the problems and seeing if the statements are always true. 1)correct 2)If b is 2, then you have -2 + -2 = -4... 3)Try to plug in x=-1

**arithmetic**

What's your question? All you would do is weigh each one and write down the weights. The heaviest one would not get eaten and the others would.

**math**

Estimates can be greater than the actual sum, less than, or the same as. It depends on the actual problem.

**math**

1/4 (no work to be shown). You just multiply straight across and then reduce, if possible. It wasn't in this case.

**mat115**

11-6/7=10 1/7 10 1/7-7= 3 1/7

**algebra1**

You can post your answers and we can check them.

**algebra1**

You have to find a common denominator. I'll do the first one for you. 5 and 8 both have 40 as their lowest multiple. 16/40-35/40=-19/40 Post the answer to the second one if you want it checked.

**english check answer**

If you'd like to fix them, we can check them for you again.

**geometry**

3x-2y-4=-6 3x-2y=-2* 4x+4-y=7 4x-y=3* So your 2 new equations are 3x-2y=-2 4x-y=3 Multiply the bottom equation by -2 to cancel the y's gives us -8x+2y=-6 3x-2y=-2 -5x=-4 x=4/5 Plug the x value into either of your "2 new equations above" to figure out y.

**algebra and trigonometry**

9<1/2x 18<x or x>18 Find 18 on the x-axis and draw a vertical line through it. Then shade to the right of it, where x is more than 18.

**math **

Break the number down into the highest perfect square that it divides into plus whatever number you multiply it by. Examples: sqrt (square root) of 50, you break that down into 25 (perfect square) x 2, the 25 is 5 squared so your answer is 5 sqrt 2. Example 2: sqrt 147, break ...

**Geometry**

Are the two angles complementary or supplementary (add up to 90 or 180, a straight line)? If they are complementary, 5/2y+y+5=90...if they are supplementary same thing but =180 instead of 90. Post your answer if you want it checked.

**algebra1**

9.95+.5h 9.95+.5(20)=?

**math**

how many people in a seat (2?) and about how many seats, multiply them together

**algebra 1**

That's the situation. There's no response to it unless there is a number to fill in for b. In this case there isn't. B just stands for the amount of money spent in this situation. You could plug in numbers to see how it would work. Pretend you spent $9. 17-9=8. You...

**mat115**

7(-7)-7(2-3) ____________ 2(-6+9) top: 7(-7)-7(-1)= -49+7=-42 bottom: 2(3)=6 -42/6=?

**algebra 1**

Right. Always think of negative numbers as money you owe and positive numbers as money you have. I believe that's the easiest way to evaluate those expressions.

**8th grade**

4+-3x=3x 4=6x 4/6=x 2/3=x

**math**

Dreams could be one of the words..

**Alg 2**

Because each number for the range is the domain multiplied by 2. Look at each pair of numbers. domain 1, range 2...isn't 1 x 2 = 2? domain 2, range 4..2 x 2 = 4..etc

**Math**

I used guess and check until I got it. Sometimes you have to take the time to do this. q 17, d 20, n 11 = 48 q 20, d 23, n 14 = 57 q 23, d 26, n 17 = 66 q 22, d 25, n 16 = 63 The last one works. 22 quarters, 25 dimes, and 16 nickels.

**9th grade**

16. Gemini, cancer, etc (astrological signs in order)

**algebra**

The b's cancel out..and 35/105 can both be divided by 5 to reduce to 7/21 and then again by 7 to reduce to 1/3...so a/3c

**Algebra**

All you have to do is create a number game. It shouldn't be too difficult. Just make sure you "undo" what you "do". If you add five, make sure you subtract five later on (maybe just not all at once so it doesn't look as obvious). Try to create one a...

Are you solving for 6? Just subtract the 6 from both sides and you get y-6=x

**University of Phoeniz**

It means I have to get fresh air to live. I don't speak French, but by typing this in a french-english dictionary, it told me what I meant. There are plenty of french-english translators online and vice versa for you to check in the future.

**math**

Did you even try this? Factor the top, and that cancels out on the bottom, and leaves what...?

**mathhhhhh**

Correct

**math**

-7<3x-6<-5 Adding six to both sides, -1<3x<1 Dividing both sides by 3, -1/3<x<1/3 This means x is between -1/3 and 1/3

I vote for C too. I think I remember learning this in one of my psych classes.
