Here is an example:
Josh bought 7 apples for $21.
21/7 is 3, so one apple costs $3. This is the unit rate.
21/7 simplifies to 3/1, that’s another way to think about it. Simplify the fraction until the denominator is 1.
Hope this helps! Tell me if you have any questions!
Answer: x = 4
Step-by-step explanation:
x/2=10/5
<u><em>Multiply both sides of the equation by 2.
</em></u>
2⋅ x/2 = 10
/5 ⋅
2
<u>Simplify both sides of the equation.
</u>
<u>
Cancel the common factor of 2</u><u>.</u>
<u>Rewrite the expression.
</u>
x= 2 ⋅ 10/5
<u><em>Divide 10 by 5.</em></u>
x= 2 ⋅ 10/5
<u><em>
Multiply 2 by 2.
</em></u>
x = 2 ⋅ 2
x = 4

Yes, any number that doesn't repeat for along time, such as 2/3, 1/3, etc, would be considered rational, its those numbers that don't end that are irrational, meaning 0.59 is rational.
x is 8...

Answer:
This problem is a great systems of equations problem--you have two different variables: song size and number of songs.
Let's call the number of standard version downloads (S) and the high quality downloads (H).
You can make two statements:
For number of songs downloaded: S + H = 910
For download size: 2.8(S) + 4.4(H) = 3044.
S will be the same number in both equations and H will be the same number in both equations, so to find S, we can rearrange the first statement to H = 910 - S, then substitute or plug in (910 - S) wherever you see an H in the second equation so that you have only S's in your equation. Should look like this:
2.8(S) + 4.4(910 - S) = 3044
2.8S + 4004 - 4.4S = 3044
-1.6S = -960
s = 600
Your question only asks for the standard version downloads, but to help you out in future Systems situations-
You can also solve for H once you have S by plugging it into either of your equations like this:
600 + H = 910
-600
H=310
