-8x-27=-32 1/3 Add 27 to both sides. Divide by -8.

2nd grade
Seventy four.

Good job!

Math
The hypotenuse is always the longest side and across from the right angle. So which letter does that match up with?

Math
No, the directions said to round to the nearest tenth. 6.122 rounded to the nearest tenth is 6.1.

Spanish 1
5 is right. (Still not sure about 9. Stuck between C and D.)

math
None of them are equal to -1. Please check your signs and post again. All of the answers will be positive.

Spanish 1
Try again on these: 1. It's asking what Juan is like. 5. Look up how you say Si, me gusta and no me gusta in a sentence. 8 is correct. I think 9 is also correct but I'm not 100% positive on that one.

math
3z=13 z=13/3 or 4 1/3 8x-y+(13/3)=22 8x-y=17 2/3 Should the last equation say 2x or 2z? I can't go any further until I know that.

english
You already asked this question. Have you read the book? I already know the answer from just reading the wikipedia page about it.

Math
Putting this information into the exponential growth formula gets you the equation y=100(2^x) where x equals the number of hours. Plugging in 12 for x, you get 409600.

Obesity?

math
Distributive, maybe?

math
The 67% is right, but not 375. Move the decimal over 2 places to the right, not 3. Try again.

math
No, move the decimal 2 places to the right.

Five Number Summary
It's not 6, Renee. You have to solve for x in the equation I made for you. (8+5+10+3+x)/5=6 (26+x)/5=6 26+x=30 x=?

Five Number Summary
(8+5+10+3+x)/5 = 6

College Algebra
Agreed, Kelly. Good for you. I think what Reiny was getting at is at the origin the point is (0,0) so it is possible. Not 100% positive though.

College Algebra
Why do you have to make degrading comments all the time? Either help or don't.

math
x+4y=-16 (1) 3x+2y=12 (2) Multiply (1) by -3 to get the x's to cancel -3x-12y=48 (3) 3x+2y=12 (2) Now add (3) and (2) together. -10y=60 Divide by -10. y=-6 Substitude y=-6 into equation (1) or (2) to solve for x.

agebra
L=laser tag, V=video games 3L+5V=17 (1) 4L+7V=23 (2) Since the question asks only about the video games, we want to eliminate the L's. We can do this by multiplying the first equation by 4 and the second equation by -3. 12L+20V=68 (3) -12L-21V=-69 (4) Add 3 and 4 together...

Math
The digit is 6.

math
1, 3, 9, 27, 81, 243, 729, 2187 (you just had to multiply each number by 3 to get the next)..now add all of these numbers together

8th grade
Is just the 3 to the zero power or the 5-3?

math
Get out a calcutor and do 1/8, then move the decimal two places to the right and put a percent sign after that number.

English: Vocab
Definitely not! What are you trying to say?

math
.68 * 13 = 8.84

math
3x+4=5x-7 You want to get the x's on one side and numbers on the other. First, subtract 3x from both sides. 4=2x-7 Now add 7 to both sides. 11=2x Divide both sides by 2. 11/2=x 5 1/2=x

7 feet tall? Wow, he is tall. I would agree with Jay.

math
5 15/100=5 3/20..as a mixed number 103/20 (denominator stays the same, multiply the 5*20 then +3 to get 103)

fractions word problems fifth gradee
They are both right. The easiest way to do this is to make a proportion, though. 2.5/30=x/120, Cross multiply 30x=300, solve for x.

math
9+6=15, 10+5=15

math
2.9166667 is not the same as 2 1/2. 2 1/2 would be 2.5. You could say 2.9 feet.

math
She is not going to give you the answer. The answer is what you get when you do 35 divided by 12.

Bethany has 40 apples. She gave 17 to her brother. How many does she have left? 40-17=23

math
The arithmetic post was already answered. Kim, please post a new question instead of "tagging" on the end of someone else's. 1/3 of a number can be written as 1/3x (or any other letter attached).

math
3a+8=15-(9a-9) 3a+8=15-9a+9 3a+8=24-9a 12a+8=24 12a=16 a=16/12 a=1 1/3

Math
.27 repeated..because 3/11 is less than 1, see that? There is no whole number in front of the fraction so it can't be 3.6.

algebra
16/2t=2 8t=2 t=2/8 t=1/4

Spanish
1. You would say "Si, estudio mucho" because it's asking do you study a lot and you would typically respond yes, i study a lot (as opposed to yes, i like to study a lot). Do the same thing for #2.

algebra
-13(4+2a)=208 Distribute -52-26a=208 Add 52 to both sides -26a=260 Divide both sides by -26 a=-10

math

math
Yes, but what you had should have been 147/1000=.147 Did you not see my post?

5th grade
Pat, I already told you. The first one should be 700,000.

5th grade
1. 189,103+504,200=693,303 Estimate would be 200,000+500,000=700,000. I'm assuming you have a typo and forgot the 0 for that option

5th grade math
No, 10*100=1000, not 10,000 so your decimal would be .147

math 5th grade
Jill, they can all be divided by 5.

math
You cannot simplify this.

Math
Do you understand, Bridgett? You just multiply that number through 1. Examples: 8!=8*7*6*5*4*3*2*1, 3!=3*2*1, 12!=12*11*10*9*8*7*6*5*4*3*2*1.

math
2L+2W=780 L=4W+15 2(4W+15)+2W=780 8W+50+2w=780 10W+50=780 10W=730 W=73, substitute this back into either original equation to find L, L=307

Use principles of force and kinematics to answer these: a. A 40 kg skater pushes on the 60 kg skater (initially at rest). As they collide, the 40 kg skater pushes on the 60 kg skater, applying a force 100 Newtons for 1.2 seconds. Find the velocity at which each of them ends up...

7 and 8 seem repetitive. You said you can help them take a bath in 7 and help them wash their bodies in 8. That's really the same thing.

sports math
Play around with the numbers until you get 20. How is this sports math?

fraction
Reduce first: 3/4 * 1/2 * 2/3 Write them side by side and cross simplify You can cross out the 3's and write 1's and you can cross out the 2's and write 1's Now you are left with 1*1*1/4*1*1=1/4

10th grade
Are they corresponding angles? If so, 2x-3=x+39. Are they supplementary angles? If so, 2x-3+x+39=180. Are they complementary angles? If so, 2x-3+x+39=90.

spanish
You don't conjugate it. You conjugate verbs, and tarea is a noun. It means homework.

What do you think the main idea of this paragraph is? If you attempt to answer the questions with explanations, the tutors will be more willing to help you.

general question
No, you have to post them here.

No, 32 3/5 cannot be simplified.

Chemistry
No to all the above

math
L=7W 2L+2W=72 2(7W)+2W=72 14W+2W=72 16W=72 W=4.5, now substitute that back in either original equation to solve for L and L=31.5 Substitute in both original equations, both work.

I'll be honest, I don't know if you are right in the beginning. I can, however, tell you how to continue from 4x^2=100, if you are right up until that point. 4x^2=100 Divide both sides by 4. x^2=25 Take the square root of both sides. x=+-5

A fact is something that can be proven to be true. Examples: the sky is blue, 12*10=120, the capital of NJ is Trenton. We can check on any of these things if we do not know. An opinion is something that cannot be proven. Examples: blue is the best color, that shirt is nice. (...
