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.

-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.

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.

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.

What about the 2?

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

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

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.

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.

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.

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.

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...

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.

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.

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...
