Marcus is picking songs to play during a slideshow. The songs are each 3\dfrac123 2 1 3, start fraction, 1, divided by, 2, end fraction minutes long. The slideshow is 31\dfrac1231 2 1 31, start fraction, 1, divided by, 2, end fraction minutes long.

Answers

Answer:

number of songs = 9 songs

Step-by-step explanation:

According to Marcus the the song are each 3 start fraction , 1 divided by 2 end fraction minutes long. This can be expressed mathematically as 3 1/2 minutes long.

The slide show is 31, start fraction , 1 divided by, 2 end fraction minutes. This can be expressed also as 31 1/2 minutes long. The slide show contains the entire song.

Recall each song is 3 1/2 minutes long . The whole number fraction can be converted to improper fraction as 7/2 minutes long.

The whole slides show can be converted to improper fractions as 63/2 minutes long.

The number of song in the slideshow can be solved when we divide the total time in the slideshow by the time of each song.

number of songs = 63/2 ÷ 7/2

number of songs = 63/2 × 2/7

number of songs = 63/7

number of songs = 9 songs

Solve the system using the method of your choice: y = 3x – 4 2x + 4y = 26 SHOW WORK

Answers

Hello Savanna

y=3x-4

2x+4y=26

Can we solve it together ? :) Thx

We need to solve y=3x-4 for y

Now let's start solving this by substitute 3x-4 for y in 2x+4y=26

2x+4(3x-4)=26

14x-16=26

Now let's add 16 to both sides

14x-16+16=26+16

14x=42

Divide both sides by 14 so we can find the value for x

14x/14= 42/14

x=3

Good job:) now we find the value of x

We are not done yet.

Let's find the value for y by substitute 3 for x in y=3x-4

y=3x-4

y=(3)(3)-4

y=9-4

y=5

Yeah well done :)

Final answer : x=3 and y=5
