Answer:
10-x
Step-by-step explanation:
The total amount is made up of movies and music
total = movies + music
10 = x+ music
Subtract x from each side
10-x = x+music-x
10-x = music
Answer:
The price of the glove is $8.5 and the price of the hat is $6.5.
Step-by-step explanation:
2x+4y=43
2x+2y=30
---------------
2x+4y=43
x+y=15
--------------
x=15-y
2(15-y)+4y=43
30-2y+4y=43
30+2y=43
2y=43-30
2y=13
y=13/2
x+13/2=15
x=15-13/2
x=30/2-13/2=17/2
x=17/2, y=13/2.
The price of the glove is $8.5 and the price of the hat is $6.5.
Answer:
x=-1, y=-7
Step-by-step explanation:
8x-2y=6
3x+3y=-24
Multiplying the topmost equation by 3/2:
12x-3y=9
3x+3y=-24
Adding the two equations together:
15x=-15
x=-1
Plugging this back into a previous equation:
8(-1)-2y=6
-8-2y=6
-2y=14
y=-7
Hope this helps!
Answer:
Roger will have to sleep 2.667 days.
Step-by-step explanation:
If Roger sleeps 3 / 8 of a day in one day.
Then for Roger to sleep the equivalent of one day he will have to sleep
![=\frac{1}{\frac{3}{8}} = \frac{8}{3} = 2\frac{2}{3} = 2.667\hspace{0.1cm} days](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B%5Cfrac%7B3%7D%7B8%7D%7D%20%20%3D%20%5Cfrac%7B8%7D%7B3%7D%20%20%3D%202%5Cfrac%7B2%7D%7B3%7D%20%20%3D%202.667%5Chspace%7B0.1cm%7D%20days)
