Answer:

10 one-dollar  and 4 five-dollar bills.

Step-by-step explanation:

Let x = the number of one-dollar bills and y = number of five-dollar bills.

Then:

x + y = 14

x + 5y = 30      (using the values of the bills)

Subtracting the 2 equations:-

-4y = -16

y = 4

so x + 4 = 14

x = 10.

There are 10  one-dollar bills and 4  five-dollar bills.

Answer:

The equivalent ratios are:

16:10

8:5

48:30

Step-by-step explanation:

It is given that the ratios are equivalent ratios. So all the ratios will simplify to the same ratio. We can use this to find the ratios.

given ratio is:

16:10

which simplifies to

8:5

We can observe that the second ratio will be same 8:5

Now,

\frac{8}{5} = \frac{x}{30}\\x = \frac{8}{5} * 30\\x = 48

Hence,

The equivalent ratios are:

16:10

8:5

48:30
