Applications for a cellular phone cost $0.79 each. ringtones cost $1.89 each. write an algebraic expression that represents the total cost of buying a applications and r ringtones.

The answer to your question is:        C = 0.79a + 1.89r

Step-by-step explanation:

Data

Cost = C

apps = $0.79 = a

ringtones = $1.89 = r

                C = 0.79a + 1.89r

f(x)=2/3x-8, which give g(x) the greatest value.

step-by-step explanation:

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
