MATH HELP! Due tomorrow! Im Stuck!?
Presuming: (3/x) + 2 and (2/x) - 2 Subtract one from the other. 3/x + 2 - 2/x + 2 = 1/x + 4 (where, of course, x isn't zero) Make sense? If it's 3/(x+2) and 2/(x-2), you have to multiply the first by x-2/x-2, and the second by x+2/x+2 That gives you 3(x-2)/(x^2-4) and 2(x+2)/(x^2-4) Now, subtract one from the other, you get [(3x-6) - (2x+4) / (x^2-4) = (x-10)/(x^2-4) where, of course, x isn't 2 or -2. Actually, probably ought to be |(x-10)/(x^2-4)| since we don't know whether x is positive or negative.

Ok. We need to find out the values of the 5s. Values are like tens, ones, and hundreds. For example, 555 would be 500+50+5 in which the 5 in the tens place's value in 50. The value of 5 in 56= 50+6 Value=50 The value of 5 in 90.35= 90+.30+.05 Value+.05 Now, how do you get from .05 to 50? Well, you could always divide 50 by .05. What do you get? 1,000. 1,000 times= Answer *NOTE*- Please check whether I made a mistake!

Hi. First, you are going to assign your variables. Full-grown giraffe: 6x Lion: x Cheetah: .25x Now, add them all together, and set them equal to 450 kg. 6x + x + .25x = 450 Now, add like terms and find x. 7.25x/7.25 = 450/7.25 x is approximately 62 kg. Check it by plugging in 62 for each x. 6(62) + 62 + .25(62) 372 + 62 + 15.5 = 499.5 Full-grown giraffe: 372 kg Full-grown lion: 62 kg Full-grown cheetah: 15.5 kg Hope this helps!
Need help w. my math hw. Due Tomorrow* Please Help!?
Really :)) Have you ever heard of the word "calculator"? You could try one of these: http://www.calculator.com/calcs/calc_sci... http://www.motionnet.com/calculator/ :D Sorry I didn't want to be sarcastic but this "question" made me laugh... You could try to do the exercise yourself, it's easy. That's what I was doing at school 4 years ago...and now I'm 15 years old.
Math homerwork help plz....due tomorrow...grade 9?
You disect the problem into equations. Say your one-way trip distance is y. You know that you travelled the same distance both ways. On the way there it took you T1 hours. On the way back T2 hours. So... 400 km/h * T1 = y 500 km/h * T2 = y This means 400 km/h*T1 = 500 km/h*T2 Divide both sides by 400 km/h, you get T1 = (500/400)* T2 -- call this equation 1 Also, T1 + T2 = 9 h -- call this equation 2 Substitute the T1 from equation 1 into equation 2 (500/400)*T2 +T2 = 9h or (5/4 +1)*T2 = 9h T2 = 9h/(5/4 +1) T2 = 4 h Subsitute that into the second equation at the top 500 km/h * T2 = y You get y = 2000 km The total trip there and back, is therefore 4000 km.
