Beth rented a bike from julia's bikes. it cost $19.60 plus $6 per hour. write an expression for the total cost beth had to pay

c = 6t + 19.60

Step-by-step explanation:

   Let t = the time in hours for which Beth rented the bike. Then  

       6t = the rental cost for the bike and

$19.60 = the up-front cost

The expression for the total cost (c) is

c = 6t + 19.60

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
