If x/5 = -6, then you cross multiply pretending that there is a 1 under the -6 like...x/5 = = -6/1. Therefore, (5)(-6) = x and x = -30
A very big number!!!!!!!
What do you mean?
Hit the "2nd" button......you'll see it on the top tier of buttons......
(279 - 248) /279 =
31 / 279 = (about 11.1%)
Mainly...by answering questions.....we like correct answers, but, if you make a good effort, we often reward that, too!!!
We also give some points for just "goofing off"....especially if you're witty or you provide us with some deep thoughts for the day !!!!
Remember........ only Chuck Norris (and kitty<3) can successfully divide by zero.....all others are doomed....!!!!
Any number divided by zero is undefined. Don't try it.

cubedsqrt250x^7y^3/cubedsqrt2x^2y =
3√(250*x^7*y^3)/ 3√(2*x^2*y) = 3√(125*x^5*y^2) = (5x)[3√(x^2*y^2)]
$$$$\sqrt{27x^2y^2z}=\sqrt{3*3^2*x^2*y^2*z}=3*x*y*\sqrt{3z}$$\\ or $$3xy\sqrt{3z}$$
125*a^2-5*a^2=120*a^2
15/100=tg(alpha)=25/lenght of the projection of the road on the ground
0.15=25/proj
proj=25/0.15
proj=166.666
lenght=sqrt(proj^2+height^2)=168.524
We need to use the sine for this.....we know an angle, an opposite side..... and we need to find the hypoteneuse.....
We have....
sin(15) = 25/h ...where h = the hypoteneuse = road length
Multiply both sides by h and divide both sides by sin(15)..so we have...
h = 25/sin(15) = (about 96.6 yds)
15/100=tg(alpha)=25/lenght of the road
0.15=25/lenght
lenght=25/0.15
lenght=166.666
rosala is correct, Amonymous......you made a "lucky" mistake.....because 10/1 = 10(3-2).....but..if we had..... 10(7-2) = 10*5, we couldn't claim that it = 10/(7-2)= 10/5.....!!!
Not rosala ! I have respect !But Zegroes should understand!oh poor Zegroes!lol!
And for fossil i have the most respect becoz they r very important, the remains of old age!!!!
I didnt knew maths was in old age too!
rosala and zegroes should have more respect for their elders...!!!! (LOL!!).....particularly......"old fossils"
I think you made a mistake in the 2nd step which is like this
10 x 10 + 10 / 1
instead u had to multiply 10 by 3 and 2 and then subtract!
But still the answer is coming correct but if the method is wrong the whole thing can be marked as wrong!
here's what im getting
10 x 10 + 10 (3-2)
100 + 10 =
110
hmmm!I think thats the problem with most of the people of your age!
You know CPhill i just had a thought when u said at my age, i thought that if Zegroes would be here he would surely have a lovely answer for you , whom he calls fossil!lol!
That would be pretty fun to see!
x=(8y-92)/12
7((8y-92)/12)=-3-8y
56y-644=-36-96y
152y=608
y=4
x=(8*4-92)/12
x=-5
