Answer 1

Plug in 6 for x and 4 for y in the equation.

Answer 2

It would be 39 right

Answer 3

Right :)

Answer 4

Thnks;) a hace another question

Answer 5

What is it?

Answer 6

What is the value of the expression 1/3 t + 2/3r if t =9 and r =6?

Answer 7

Plug in 9 for t and 6 for r in the equation.
1/3(9) + 2/3(6).

Answer 8

I know i dont get tht one :( my ópticos r 5, 7 or 9 but i cant find the anwered :(

Answer 9

Okay, let's break it down. What is 9/3?

Answer 10

Instead of trying to find (1/3) * 9, you can covert 9 into a fraction and multiply. 9 as a fraction is simply 9/1.
\[\frac{ 1 }{ 3 } * \frac{ 9 }{ 1 } = ?\]

Answer 11

Dont get it sorry:(

Answer 12

What part is confusing you?

Answer 13

Ok the result is suppose to be A. 5 B. 7 or C. 9 and I'm not getting the result

Answer 14

Okay, let's go back tot he beginning and just look at the equation.
\[\frac{ 1 }{ 3 }t + \frac{ 2 }{ 3 } r\]
Plug in the values for t and r, which are given to you. t = 9, r = 6.
\[\frac{ 1 }{ 3 }(9) + \frac{ 2 }{ 3 } (6)\]
There are a couple ways to figure this out, but the easiest would be to convert the 9 and the 6 into fractions.

You know what 9 as a fraction is \[\frac{ 9 }{ 1 }\] because 9/1 = 9.

Then we can simply multiply.
\[\frac{ 1 }{ 3 } * \frac{ 9 }{ 1 }\]
Multiplying fractions is very easy. You just multiply the top numbers, then you multiply the bottom numbers.
So let's multiply the top numbers first. The top numbers are 1 and 9. 1*9 = 9.
Now let's multiply the bottom numbers. The bottom numbers are 3 and 1. 3*1 = 3.

Now let's go back and write that as a fraction again.\[\frac{ 9 }{ 3 }\].
What is 9 divided by 3?

Answer 15

3

Answer 16

But that's not in the answered tht I can choose

Answer 17

That's only the first part of the equation. So 1/3(9) = 3.

Now let's look at the second part of the equation. 2/3(6). You have to convert 6 into a fraction, which is simply 6/1 because 6/1 = 6.
\[\frac{ 2 }{ 3 } * \frac{ 6 }{ 1 }\]
Multiply the top numbers, which are 2 and 6. 2 * 6 = 12.
Now multiply the bottom numbers, which are 3 and 1. 3 * 1 = 3.
Now let's write that as a fraction.
\[\frac{ 12 }{ 3 }\]
What is 12/3?

Answer 18

Is 4 but is not in there is either 5 , 7 or 9 :(

Answer 19

So 1/3(9) + 2/3(6).
We know that 1/3(9) = 3 and 2/3(6) = 4.
So what's 3 + 4?
