In this problem: 5/12b + 15/36b^2 First I made a common denominator: 15b/36b^2 + 15/36b^2 Then I simplified the first fraction: 5/12b + 15/36b^2 Can I simplify the second fraction by 3b? If I can, what am I supposed to get?

Math
Are you sure it isn't 10b?

Math
In (8b+2b^3)/(b-1), Do you have to put a zero coefficient in it?

Math
Which ordered pair is a solution of the system of equations y=x^2-x-20 and y=3x-15? a. (-5,-30) b. (-1,-18) c. (0,5) d. (5,-1) When I solved the system of equations I got 5 and -1. What do I do next?

Math
How do you do this, I keep on getting 3.. There is a right triangle. One angle is 30 degrees. The hypotenuse is 24. What is the value of x, the adjacent, to the nearest whole number? a. 12 b. 14 c. 21 d. 28

Math
Thanks

Math
What is an equation of the line that passes through the points (3,-3) and (-3,-3)? how do you figure this out: a. y=3 b. x=-3 c. y=-3 d. x=y

Math
I used an online graphing calculator..so maybe it's different like that?

Math
thanks

Math
Suppose Triangle ABC has right angle C. Find the measures of the other sides to the nearest whole number if...? the measure of angle A is 32 degrees, and the measure of AB is 42. For one side, I got 23, and for the other side, I got 35. Am I right?

oh, I forgot all about that..thank you!

French
in this: Question: ¨¤ qui aimes-tu rendre visite? Response: J'amie rends visite ¨¤ ma cousine. So my mistake was that it was supposed to be rendre, but I don't understand why..aren't you supposed to conjugate it to rends?

Math
thanks

Math
There's a right triangle. There's an angle that measures 41 degrees. The hypotenuse is x, and the angle opposite 41 degrees measures 25 in length. How can I find what x is? The proportion set up is 25/x, but how do you solve for x?

science
is able to change shape. this requires energy

Math
50. If you take half of 50, it's 25.

French
are you sure? This question was on a quiz I took, and my teacher circled rends and took off a point..

French
No, that was a typo. I meant to say J'aime. and both question marks are a with an accent grave.

French
What's wrong with my response in this: Question: À qui aimes-tu rendre visite? Response: J'amie rends visite à ma cousine.

how did you get (10/12) sqrt 3?

Math
How do you simplify 5/¡Ì12? I know you have to multiply the denominator,¡Ì12, by a radical to make a perfect square.. I think you're supposed to multiply it by 12? But there seems to be other numbers multiplied by 12 that can make a perfect square...

Math
how do you solve this system? I'm using substitution.. y=3x+4 y=-x^2 First I combined it: -x^2=3x+4 I don't know how to solve it now..

A math class has 25 students. There are 13 students who are only in the band, 4 students who are only on the swimming team, and 5 students who are in both groups. How many students are not in either group? I think it's 3 students?

French
thank you

French
is this correct too? this is what i ended up writing: La matière la plus utile est les sciences.

French
In French, how do you say "The ost useful subject is science? I need to know how to say the science part..is it plural, like math, and is it masculine or feminine?

French
thanks

French
yeah, that's the one! i remember now thanks

French
is there another way?

French
how do you say "subject" in french? I think there's one way to say it that starts with an m?

Math
the ways above is probably easier, but my teacher probably wants me to solve it by factoring..

how do you factor 2c^2-7c=-5? I know that you have to change it to 2c^2-7c+5=0. Then you do this: (2c )(c ). But how do I find the two numbers? I can't think of one that works..

thanks, but can you explain my second question?

why doesn't density depend on size? If you cut a block in half, and put it in water, wouldn't the density change because I think half a block wouldn't sink all the way in water?
