Answer:
One 8x10 photo costs $1.50.
Step-by-step explanation:
You can write two equations and use a system of equations.
Let w = price of 1 wallet-size photo.
Let n = price of 1 of 8x10 photo.
Basic package:
24w + n = 19.5
Deluxe package:
32w + 3n = 28.5
We have a system of equations:
24w + n = 19.5
32w + 3n = 28.5
Multiply both sides of the first equation by -3.
Rewrite the second equation below it and add the equations.
-72w - 3w = -58.5
(+) 32w + 3n = 28.5
---------------------------------
-40w = -30
w = -30 / -40
w = 0.75
24w + n = 19.5
24(0.75) + n = 19.5
18 + n = 19.5
n = 1.5
Answer: One 8x10 photo costs $1.50.
Answer:
x = -10
Step-by-step explanation:
![2(x + 3) = x - 4 \\ 2x + 6 = x - 4 \\ 2x - x = - 4 - 6 \\ x = - 10](https://tex.z-dn.net/?f=2%28x%20%2B%203%29%20%3D%20x%20-%204%20%5C%5C%202x%20%2B%206%20%3D%20x%20-%204%20%5C%5C%202x%20-%20x%20%3D%20%20-%204%20-%206%20%5C%5C%20x%20%3D%20%20-%2010)
Answer:![9.33\ cm^3](https://tex.z-dn.net/?f=9.33%5C%20cm%5E3)
Step-by-step explanation:
Given
The dimension of the prism is
Length ![l=\frac{8}{5}\ cm](https://tex.z-dn.net/?f=l%3D%5Cfrac%7B8%7D%7B5%7D%5C%20cm)
width ![w=\frac{10}{3}\ cm](https://tex.z-dn.net/?f=w%3D%5Cfrac%7B10%7D%7B3%7D%5C%20cm)
height ![h=\frac{7}{4}\ cm](https://tex.z-dn.net/?f=h%3D%5Cfrac%7B7%7D%7B4%7D%5C%20cm)
The volume of Prism is ![V=l\times w\times h](https://tex.z-dn.net/?f=V%3Dl%5Ctimes%20w%5Ctimes%20h)
Putting values
![\Rightarrow V=\dfrac{8}{5}\times \dfrac{10}{3}\times \dfrac{7}{4}=\dfrac{560}{60}=9.33\ cm^3](https://tex.z-dn.net/?f=%5CRightarrow%20V%3D%5Cdfrac%7B8%7D%7B5%7D%5Ctimes%20%5Cdfrac%7B10%7D%7B3%7D%5Ctimes%20%5Cdfrac%7B7%7D%7B4%7D%3D%5Cdfrac%7B560%7D%7B60%7D%3D9.33%5C%20cm%5E3)
