hoa [83]

<span>Let us use the variable x for length. So width will be 1/2x + 3. Perimeter = x+x+ 1/2x + 3 +1/2x + 3 = 3x + 6 = 66 Therefore 3x = 66-6 = 60 So x = 60/3 = 20 The length is 20 cm. Therefore the width = 1/2 of 20 + 3 = 10 + 3 = 13 cm Check: 20+20+13+13 = 66</span>

For a new customer, a video store charges $10 for a rental card plus $2 per movie. Using the linear equation (y=mx+b) you wrote,

netineya [11]

Given:

Charges for rental card = $10

Charges for movie = $2 per movie

To find:

The linear equation for given situation and find the cost to rent 6 movies.

Solution:

Let y be the total cost for x number of movies.

Cost of one movie = $2

Cost of x movies = $2x

Total cost = Charges for rental card + Charges for x movies

$y=10+2x$

Put x=6 to find the cost of 6 movies.

$y=10+2(6)$

$y=10+12$

$y=22$

Therefore, the total cost for a new customer to rent 6 movies is $22.
