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

.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.

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.

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

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.

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

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.

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
