Answer 3

First, let's not pay attention to the r/5 part, let's replace it with a question mark


So

? - 6 = -1

Answer 4

is it 5?

Answer 5

Correct

So the ? is 5 and if we look at the question the ? was also replaced by the r/5, which means they are the same thing

5 = R

5

Would you have an idea on how to solve this?

Answer 6

no im still confused

Answer 7

So what we first did was found a way for the ? to mean two things

We had r
- - 6 = -1, so we made the r/5 a question mark to make it one thing
5

Then we decided to make the ? and did ? - 6 = -1

We found 5 was the answer to our other thing, so we set those equal

R
- = 5, reading what divided by 5 gives you 5
5

That make sense so far?

Answer 8

yus

Answer 9

So now we need to find

? divided by 5 gives you 5

So 5/5 = 1 and 10/5 = 2, right? You see that pattern of counting by 5's

Answer 10

kinda

Answer 11

Let's set it up like this

We know that anything over 1 is just that number, so 5 is also 5/1

5 R
- = --
1 5

Do you know how to solve proportions by cross multiplying and dividing?

Answer 12

kinda so 5*5 and 1*?

Answer 13

Yes, close!

We have the ? as R, so it would be 5*5 and 1*R, but if we multiply a number by one, it's just that number, right? Same with variables/letters

So we'd have 5*5 = 1R or 5*5 = R

Answer 14

oh ok

Answer 15

What would you get with R if you did,

5*5 = R

Answer 16

25?

Answer 17

Correct! so R = 25

Answer 18

thanks!!

Answer 19

Anytime!
