Sergeeva-Olga [200]

To solve this equation you need to find the value of x.
You can do this by using inverse operations.
and getting x alone.
x/4=5
the opposite of division is multiplication so we multiply 5 by 4
x=5*4
we now have x alone and must solve the rest of the equation
5*4=20
There for x=20
The recipe originally made 20 servings.

Answer:

6.125 minutes per song

Step-by-step explanation:

Unit rates are based on a single unit of something. Like price per 1 gallon of gas; price for 1 pound of bananas; miles driven per 1 gallon of gas, etc. What we are looking for in minutes per song.

Use a proportion to solve this with minutes on top and number of songs on the bottom. We know that 49 minutes = 8 songs, and we want to know how many minutes (x) per 1 song:

$\frac{min}{song}:\frac{49}{8}= \frac{x}{1}$
