Answer:
16/20
Step-by-step explanation:
4:5
Multiply each side by 4
4*4: 5*4
16:20
16/20
60 hundreds if it says hundreds then it would still be that
The ratio is 3:5.

You have to divide 72, so the sum of x and y is 72.

Set both expressions equal to each other:

72 divided in a ratio of 3:5 is
27:45.
For this case we have that the variable "y" represents the total cost of the annual club membership.
For its part, the variable "x" represents the number of months.
Now, we have the following function:

If you want to know the annual amount, then 

Thus, the total annual amount is 288 dollars.
ANswer:
$ 288
Y = 2 x + 3
We will plug in the numbers from the sets:
1 = 2 · ( -1 ) + 3 = - 2 + 3= 1 ( correct )
3 = 2 · 0 + 3 = 0 + 3= 3 ( correct )
7/3 = 2 · (-1/3 ) + 3 = -2/3 + 3 = - 2/3 + 9 /3 = 7/3 ( correct )
Answer : A ) { (-1, 1 ), ( 0, 3 ) , ( -1/3, 7/3 ) }
