A game charges $0.99 for custom skins and a $9.99 membership fee. Write and expression that gives the total cost in dollars for c number of skins and a membership.

0.99c + 9.99

Step-by-step explanation:

We know one part of the expression is going to be $0.99c, since it's $0.99 per custom skin, and c is the number of custom skins were getting.

Then we must add on the 9.99 on top of that, since that is the one-time membership fee. This is what the equation looks like :

0.99c + 9.99

Hope this helps :)

5. y = $0.99c + $9.99

Step-by-step explanation:

To find the cost, let us solve the equation for y:

Plug 5 as a replacement for c

y = 0.99(5) + 9.99

y = 0.99 × 5 + 9.99               multiply

y = 4.95 + 9.99                     add

y = 14.94

Therefore, the answer to number 6 is $14.94, which is the cost of 5 skins.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
