For the first question shade all the boxes in the first 3 boxes & in the 4 box only shade in 59 boxes to represent the 3.59$
After solving
we get ![4x-20y-8](https://tex.z-dn.net/?f=4x-20y-8)
Step-by-step explanation:
We need to solve ![2x+16y-36y-9+1-x+3x](https://tex.z-dn.net/?f=2x%2B16y-36y-9%2B1-x%2B3x)
Combining the like terms:
![2x+16y-36y-9+1-x+3x\\=2x-x+3x+16y-36y-9+1\\=4x-20y-8](https://tex.z-dn.net/?f=2x%2B16y-36y-9%2B1-x%2B3x%5C%5C%3D2x-x%2B3x%2B16y-36y-9%2B1%5C%5C%3D4x-20y-8)
So, After solving
we get ![4x-20y-8](https://tex.z-dn.net/?f=4x-20y-8)

Answer:
32 coins
consider the value of a group of coins
Step-by-step explanation:
The coins are in equal numbers, so they can be considered as a group. The value of one group of 4 coins is ...
1¢ + 5¢ + 10¢ + 25¢ = 41¢ = $0.41
Then the number of groups (g) of coins is ...
$3.28 = $0.41×g
g = $3.28/$0.41 = 8
There are 8 groups of coins. Each group has 4 coins, so there are ...
(8 groups)×(4 coins/group) = 32 coins
Answer:
I believe the answer is C :)
Step-by-step explanation:
Area = Length x width.
The area of the wall is 8 x 8 = 64 square feet.
The area of one window is 4 x 5 = 20 square feet.
The area of the 3 windows is 20 x 3 = 60 square feet.
The percentage would be (area of windows / area of wall) x 100
Percentage = 60/64 = 0.9375 x 100 = 93.75% (round answer as needed)
