This is a homework help website. You just post the subject, instead of grade, and ask a specific question. For example, if you don't understand how to do a math problem, post "math" for subject, and then post the problem.

I think you set it up like this..not positive though: 4(8n+6)=2(13n+2)+30n-28

Correct.

I'm sorry anonymous! You're right, I'm wrong.

10^3= 10000 Put the decimal after the 10 and move it over 3 places. Do the rest that way.

Math
I'm not sure, sorry.

48? It appears that the x's are counting by 2's, and the y's are counting by 10's (starting at 8).

No, we do not have nor would we give answers.

Math
It's not a multiple choice question, Bridgett, it's a multiple part question. Heather, I'll do part a for you and then you can do the rest the same way. You are just substituting into the equation. 3x^2+2x-3 (make sure this is right, I think you had a typo) a) x=-2...

math
Yup, Bridgett is right.

math
2.5 x 10^2=__x10^3 2.5 x 10^2= 250 .25 x 10^3=250 The exponent tells us how many places to move the decimal. If the exponent is positive, move it to the right. If the exponent is negative, move it to the left.

1, 2, 3, 4 to make 7 (4+3)x(2-1) 13 (4x3)+(2-1) 17 and 39, I can't think of..keep playing around with the numbers.

Math
Is this 3x+23=7x? Or is there a sign between the 7 and x? If it's 3x+23=7x.. 23=4x 23/4=x

Algebra
You just found out what they have in common. All of the terms have at least an x^2, so you can take that out. All of the numbers can be divided by 2, as well, so your GCF is 2x^2.

(x-1)^2=sqrt6^2 Take the square root of both sides. x-1=sqrt6.. you have to know how to finish from here

I'm pretty sure she meant 3142, 6328, & 4743.

The first step is to add those numbers up. Let me know what you get and I'll tell you what to do from there.

r+s=10 2r+4s=27 Multiply the first equation by -2 to cancel the r's. -2r-2s=-20 2r+4s=27 2s=7 s=3.5 Put s back into either original equation to solve for r (the first one would be easier).

Good job!

xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx 4 x 8 = 32 The first number always goes down and the second number always goes across because 4 x 8 = 32 means 4 groups of 8. You can use any symbol, not just X's.

26x>90 solve for x, x would be rounded up to the nearest whole number

4th grade
x + y = 40 x = y + 12 Use substitution to plug the second equation into the first. y + y + 12 = 40 2y + 12 = 40 2y = 28 y= 14 Plug y = 14 back into either top equation, x = 26

math
Prime means the number cannot be divided by any other numbers besides itself and 1. Composite is when the number can be divided. Try using a calculator to see if those numbers are divisible, or use divisibility tricks if you know them.

math
evaluate the following when x=-3, if possible /x/=/-3/=3 -x^2=-3^2=9 -(1+x)=-(1-3)=--2=2

math probelm need serious help!!!
Please have patience. Sometimes responses could take more than a few minutes. 4x-(9-3x)= 8x-1 Distribute 4x-9+3x=8x-1 Combine like terms 7x-9=8x-1 Get the variables (letters) on one side and numbers on the other.. Add 9 to both sides. 7x=8x+8 Subtract 8x from both sides. -x=8 ...

If this is a right angle why does Henry not use the pythagorean theorum? Since the distances are just the speeds (thanks to the 1 hour) wouldn't it be X^2 + (4x+200)^2 = 2050^2?

Is this 7 1/3-2 5/6 (seven and one third minus two and five sixths)? Make sure to include spaces next time. If so... 7 2/6-2 5/6= 6 8/6-2 5/6= 1 3/6= 1 1/2

Math
You need to take the middle term (which is 18), take half of it (9) and square it (81). You then add that number to both sides.

Area could be 2 x 24, 3 x 16, 4 x 12, 6 x 8 (and vice versa). Perimeter equals 2L+2W. If the area was 2 x 24, the perimter would be 2(2)+2(24)=4+48=52. Do this with the 3 x 16, 4 x 12, and 6 x 8, and see which has the smallest perimeter.

algebra
4r-28+3>5r+10-23 4r-25>5r-13 Add 25 to both sides. 4r>5r+12 Subtract 5r from both sides. -r>12 Divide by negative one, so you have to switch the sign. r<-12

14-8x<16 Subtract 14 from both sides. -8x<2 Divide both sides by -8. x>-1/4 The sign changed because we divided by a negative.
