Answer:

The total cost C (in dollars) to participate in a ski club is given by the literal equation :

C=85x+60

Where x is the number of ski trips you take.

1. When C = 315 ;substituting the value of C in the above equation.

315=85x+60

=> 85x=315-60

=> 85x=255

x = 3 trips.

2. When C = 485

485=85x+60

=> 85x=485-60

=> 85x=425

x = 5 trips.

First of all why is there 2 similar equation connected to one another?

Second in order to solve this all you need to do is plug in the number and solve for x

For 485

85x+60=485
85x=420
X=5

Do the same thing and you get 3

zmey [24]

Answer:

The answer is 5/6, or .833, 3 repeated.

Step-by-step explanation:

The 4 is only one side of the die, or 1/6 if the surface of the die. So the other part that is left is the other 5/6 of the surface.
