QUESTION 39

This year I will have 180 hours free in which I can watch TV or watch movies. Each movie lasts 2 hours, and I'll be able to watch each TV show for 20 hours. I have $600; each movie costs $10 and each TV show costs $40.

Let x equal the number of movies watched and y equal the number of TV shows watched

Suppose I make 5 new friends every time I watch a TV show and I make 1 new friend every time I watch a movie. How many movies should I watch and TV shows should I buy this year to maximize the number of new friends I make?

sine

step-by-step explanation:

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6

daren is correct because
