Math 2nd grade
A number cannot have greater than 7 tens and less than 8 tens. There is no number between 7 and 8.

Intermediate Algebra (Math)
You are good up until here.. -1.50x + 400 = 370 (this is correct) Then when you subtract 400 from both sides you get -1.50x=-30 Divide both sides by -1.5 x=20 lbs of pistachios, and 30 lbs of almonds

Intermediate Algebra(Math)
Your first row should be: 6.5x + 8(50-x) = 7.4(50)

math 5th grade
17a^2=2209 Divide 2209 by 17. Then take the square root of that number.

Math
5.

algebra
2, 6, 6, 10

math
The 7th square number is 49, so it has to be bigger than that.

math
It's bigger than 49, and it must be a multiple of 10 (since it doesn't end in a 5)..so your choices are 50, 60, 70, 80, 90, etc..Now check your other conditions and find your number.

algebra
10+5y=77 Subtract 10 from both sides. 5y=67 Divide both sides by 5. y=67/5

Algebra-please check
Correct. You could actually check these problems yourself by plugging in your answers.

math
There should be more information..if not, what are the directions?

math
5x+5=30

English
Yes, they are correct.

8+n=1 Subtract 8 from both sides. n=-7

algebra
y+ab

Algebra
2x^2-3x-20=0 Use the quadratic formula.

math.7th gradee.
Parenthesis means to do that operation first. The order of parenthesis changes the problem. Did you learn order of operations? PEMDAS. Look at the difference between these problems. (4+3)*2=7*2=14 4+(3*2)=4+6=10

algebra
False. The 3 is multiplied by 2 to get 6, and the 4 is multiplied by 3 to get 12. In order for the statement to be true, they would both have to be multiplied by the same number. 3/4=6/8=9/12

3rd grade
You need to add 2 digits plus 2 digits of the lowest numbers. 12 + 34 = ?

Math
4 x 6 = 24, Laura. Sorry Lola, I can't figure it out either.

Algebra
9m+2m-8=5(m-2) 11m-8=5m-10 Subtract 5m from both sides. 6m-8=-10 Add 8 to both sides. 6m=-2 Divide both sides by 6 and reduce. m=-1/3

8th grade
Did you mean 3m=8? Divide both sides by 3 and get m=8/3.

algebra)
All you did was move around the paranthesis, so that's the associative property.

math
x+2y=10 3x+2y=18 Multiply the first equation by -1 to cancel the y's: -x-2y=-10 3x+2y=18 Now add the rows 2x=8 x=? Now plug that back into either original equation to solve for y.

math
(16+____) +(14-7)=18+22 16+____+7=40 23+____=40 ____=?

math question.
Yes.

math
-2x(-6)=12x

english
What elements? You forgot to list them.

5th grade
Round: 200/5=?

Pre-Algebra
Divide both sides by 4 to get x<-4

math
32 tens and 8 ones..now you think of one

Spanish
No, it's not right. What are you trying to say?

7th grade
5x-10=2x-7 Add 10 to both sides. 5x=2x+3 Subtract 2x from both sides. 3x=3 Divide both sides by 3. x=1 This way is the more common method although Emily did get the correct answer.

algebra
13, 14 are wrong..I'm not going to check anymore..If you need help (step by step) on one or two problems, please re-post. It seems that you are just guessing.

algebra
Welcome back, Whitney. I have to leave for work but I checked as many as I could. Hopefully someone else can check the rest or I can check the rest later. I checked up to 12. They are all right except 4, 6, 7, 12 (5 I'm not sure about).

Not enough information.

__-__/__+__=50 Are you sure you have the number sentence right? You can't subtract any of those numbers and end up with that solution. You can do this though.. (50*2)/(10/5)=50

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.

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

algabra II
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.

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.

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.

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).

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.
