Multiply.

1 answer:

7 0

Use the FOIL technique (first outer inner last) to solve this.

FIRST: multiply the x and the 5x to get 5x^2

OUTSIDE: multiply the -4 and the x to get -4x

INNER: multiply the -6 and the 5x to get -30x

LAST: multiply the -4 and the -6 to get 24.

last step: put it all together to get 5x^2 - 4x - 30x + 24, which is 5x^2 - 34x + 24.

EastWind [94]

Answer:

The rental cost of one movie is $2.25 and the rental cost of one video game is $6.25

Step-by-step explanation:

Let the rental cost of 1 movie be m.

Let the rental cost of 1 video game be v.

One month, Tammy rented 2 movies and 6 video games for a total of $42. This means that:

2m + 6v = 42 ________ (1)

The next month she rented 5 movies and 3 video games for a total of $30. This means that:

5m + 3v = 30 _________(2)

We now have two simultaneous equations:

2m + 6v = 42 ________ (1)

5m + 3v = 30 _________(2)

Multiply (2) by 2, and we have:

2m + 6v = 42 __________ (1)

10m + 6v = 60 _________ (3)

Subtract (1) from (3):

10m + 6v = 60

- 2m + 6v = 42

8m = 18

=> m = 18 / 8

m = $2.25

Put the value of m back in (1):

2(2.25) + 6v = 42

4.5 + 6v = 42

=> 6v = 42 - 4.5 = 37.5

v = 37.5 / 6

v = $6.25

Therefore, the rental cost of one movie is $2.25 and the rental cost of one video game is $6.25

so we have to do 8 divide $\frac{1}{3}$ = 8/1/3 =8x3=24

dividing 8 by 1/3 by is equivalent to multiplying 8 by 3
