need help with a math problem

[staylor]

Simplify the expression, and identify the variables, coefficients, and any constant term(s) in the simplified expression.

10x * z
y 12

 

[Pogie]

Is that the whole sum??? Showed it to my OH, hes a math boffin ;D I SUCK :. And he says he needs more info.

 

[staylor]

that is the whole problem. it works out to be:

10xz/12y
which becomes
5xz/6y

 

[Pogie]

Yeah I get it till 10xz / 12y. Then do you have to divide by 2 to get 5xz / 6y.....
Is that answer not correct???

IF . . . I remember correctly and you want to simplify even more you have to multiply by 6y / 1 to remove the divide part and it will then become

30 xzy

But like I said, I SUCK at math, thats why there are computers and calculators.

 

[staylor]

no you leave it how it is...you just reduce the fraction my taking out the greatest common factor ( which is 2). I have a friend who is a college math teacher that helps me with things like that. It is so easy for her, she can do it all in her head, but I guess that is what happens when you do math for a living.

8/9x=64

need help on this one too

 

[Pogie]

she can do it all in her head

Grrrrrrrrrrrrrrrrrr, I cant even figure it out with a calculator LOL
Also on your next prob . . . . IDK. Im really hoping somebody here is better at math than me. There has to be somebody . . .

 

[staylor]

that is my hope

need help on this one too

Are you solving for x? If so, is x tied to 9 or 8x/9?

Also, what is your math class? algebra?

 

[staylor]

solving for x and the x is tied to the 9. I am taking algebra. I was able to solve it.

8/9x=64
9/8*8/9x=64/1*9/8
x=64/1*9/8 reduces to
x=8*9
x=72

Yep, that was my thought. Thanks for the challenge! Used to be a math major, but that was a loooooonnnnnnggggg time ago. And my occupation didn't do anything with math.
