"Products" Math Problem

[Kristina123]

No, you are NOT told that 5*r =g. Where does it say that? It says that (5*r)*g=g. 5r is unknown, but we know that when we multiple it by g we get g. Well what do you multiply g by to get g? The answer to that question is what 5r must equal.

How do I find r then?

 

[Steven G]

How do I find r then?

By first finding 5r. If (unknown number)*g = g, what is that unknown number? It really is simple.

The unknown number is 5r?

 

[Steven G]

The unknown number is 5r?

I don't think that you are thinking about this clearly.
Please tell be what goes into each empty parenthesis.
( )*7=7
( )* 9 =9
( )* 2/3 = 2/3
( )*(-9) = -9

After answering does questions can you please tell me what goes into these parenthesis? ( )*g = g

Now if (5r)*g = g what must 5r equal?

The unknown number is 5r?

The point is 5*r = ?

Kristina, I agree with pka. You are not ready for these problems. You need to review pre-algebra and algebra 1!!

1

 

[Steven G]

The unknown number is 5r?

But that is still unknown. I want the exact value.

 

[Steven G]

So what must 5r equal?
And then what does r equal?

 

[Kristina123]

So what must 5r equal?
And then what does r equal?

5r is 1, but r is 0.2

1?

Jomo asked you two questions:

And then what does r equal?

Those questions have different answers - which one are answering?

5r is 1
r is 0.2

Now you solved for all the unknowns.

 

[Kristina123]

Now you solved for all the unknowns.

so b = 6,
g = 30, and
r = 0.2

 

[Steven G]

so b = 6,
g = 30, and
r = 0.2

Ok, so now you have it (although I would have said that r=1/5)
Do you have a similar problem to try? Doing examples is very helpful.

I read through the entire thread numerous times again to show all of my work on one sheet of paper. I understand how to do it now. Showing everything on paper is easier to learn than figuring out sections of the math problem one at a time online, so I guess that's why my brain wasn't thinking so clearly at first. But anyways, thank you.

[MATH]5 \cdot r = g[/MATH], and g is 30 i believe so r is 6?

Assuming that all variables are non-negative see the solution here.
If you follow that link you have seen that once you have set up the problem you can use that site to solve it for you.
