I think it sounds really good but you need to work on making it into more sentences. The beginning is a very long run on sentence.

First of all, relax. All of the people that respond to these posts are VOLUNTEERS. Nobody gets paid to help you. People help because they like to help. It would be nice if the people that we help could have patience and thank us when they get help. Second of all, I am a bit ru...

You have to post questions. We do not have information from any school.

Brian, Stop switching names. All you have to do is substitute. x(x+2)=8 x^2+2x=8 x^2+2x-8=0 Use the quadratic formula and double check my work.

What is the last number? I think the last digit got cut off. The mode is the number that occurs most often. Just by looking at the data, I would guess the mode is 15 because it looks like there is more 15's than any other number. Check that.

x-125 (x is the amount you have in your bank account). You oould also do x-125=y, where y would equal have much you have left in your account after the withdrawal.

I think it's C.

10th grade
Or you can see the denominator (bottom number) is multiplied by 3 to get from 9 to 27 so you multiply the numerator top number by 3. 4 x 3 = 12

25+12=37 25-12=13 37*13=481 so the answer is 481??

What's your question?

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

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.

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

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

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

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

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.

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.

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

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.

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)

Candace is correct.

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

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.

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

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.

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.

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 ...

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.

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...

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.

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.
