One thing is you need to get x on one side and y on the other :)
8x-1/3y=16
Just like any equation you subtract 8x
8x-1/3y=16
<u>-8x -8x
</u>-1/3y=16-8x
Now you want y all alone. So you divide. To me I think you divide by -3. But you might want to check and divided by
by -1/3 (just in case)
<u>-1/3y=16-8x
</u> -3
y=-5.33(3 is repeating) - 2.6666667x
I really do this help you out! :D
42+7a= 7(6+a)
By noticing they both have a factor of 7, I was able to find the equation.
First, set a variable.
Let x = the number of songs bought.
Each song costs 2 dollars. So, we have our first term: 2x.
And there is a fee of 5 dollars for using the website.
2x + 5
And she can't spend any more than 40 dollars. Which means she can spend 40 and under.
So, 2x + 5 ≤ 40 is the answer.
The probability of the black puppy chosen would be 1 in 4.
