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
Answer: one Apple costs £ 0.20, and one banana costs £ 0.60
Step-by-step explanation:
let x = the amount of apples
let y = the amount of bananas
4x + y = 1.40
7x + y = 2
this is à system of equations
simplify the top equation to y = 1.4 - 4x
now plug that into the second equation and solve
7x + 1.4 - 4x = 2
3x + 1.4 = 2
3x = 0.6
x = 0.2
that means that one Apple costs £ 0.20
plug that back into the top equation
4x + y = 1.4
4(0.2) + y = 1.4
0.8 + y = 1.4
y = 0.6
so one banana costs £ 0.60
