math
you have to solve for x in both problems. in the first problem you have to find common denominators before adding them together. then add them together and solve for x. x=2.4 in the second problem you have to find out what x is less than. add four to both sides then divide by ...

math
like terms are terms that look the same. ex: 2x+3-2=12 the +3 and the -2 are like terms so you can combine them together. 2x-1=12

college algebra
you have to solve for x. -3(x+5)+3 distribute. you'll get... -3x-15+3=12 combine like terms. -3x-12=12 solve for x. add 12 to both sides. -3x=24 divide both sides by -3 x=-8 plug the-8 back in to x to see if your answer is right. -3(x+5)+3=12 -3(-8+5)+3=? -3(-3)+3=? 9+3=? ...

algebra 2
L=-2 because... a=lw 4=(1-3)L 4=-2L divide both sides by -2 -2=L

trig
you need to use a calculator for this.. but... sin64=.920 tan21=-1.53 cos67.4=-.144

algebra
the answers are... w=23 l=30 use this formula... 2L+2W=106 2(w+7)+2W=106 ^Factor the 2 with (W+7) then solve for W. thats the first part. then use the same formula... 2L+2W=106 plug in your W then solve for L

I was just wondering if anyone can explain the Law of Sines- "Ambiguity Case" to me, in a way that is easy to understand.

Posted by Ariel on Saturday, November 10, 2007 at 4:33pm. So I need a function (parameters: origin x, origin y, destination x, destination y, object x1, object y1, object x2, object y2). The object in this case would be a wall with two points (x1, y1, x2, y2). The function nee...

Algorithm/Function
So I need a function (parameters: origin x, origin y, destination x, destination y, object x1, object y1, object x2, object y2). The object in this case would be a wall with two points (x1, y1, x2, y2). The function needs to return a true/false if the wall intersects the path....

What volume, in ml, of a 60% of HCl acid solution must be added to 100 ml of a 30% HCl solution to make a 36% HCl solution. We need 2 alegabreic (?) equations. The first I can get is: 0.36x - 0.60y = 100ml (this is probably wrong)? Blah. I can't get the other one. -.- VolH...

Chemistry - Help balancing...
Anyone able to help me figure out the products and balance this equation? CH3COOH (aq) + NaOH (aq) -> I know it equals a salt and a base... But I can't figure out what... :P Would it possibly be... NaCH3COO + HOH for products? yes.

Chemistry
Anyone able to balance/do the equation: C8H7O2COOH + NaOH -> I can't figure out the products. C8H7O2COOH + NaOH =>C8H7O2COONa + H2O acid + base ==> salt + H2O Merci buckets. :D Oui, oui! Oui, oui! is C8H7O2COONa an acidic salt or basic salt?

math
how can we find the area of a figure. how can i find the area of this figure. jf=16 cm I can't see the figure, but generally we need to know the sides and angles in order to calculate the area.
