X=cost of bird food
dozen=12
12x=27
x=$9/4=2.25 dollars per bag
6 dozen=6×12=72bags
2.25×72= $162
Answer:
Jonathan and each of his two friends would get
of gum balls.
Step-by-step explanation:
Given:
Total Amount of gum balls = 
can be Rewritten as 
Amount of gum balls = 
Number of people gumballs has to be divided = 3
We need to find how many pounds of gum balls will they each of them get.
Solution:
Now we can say that;
Amount of gum balls each would get is equal to Total Amount of gum balls divided by Number of people.
framing in equation form we get;
Amount of gum balls each would get= 
Hence Jonathan and each of his two friends would get
of gum balls.
Answer:
Nickels are worth 5 cents. Quarters are worth 25 cents.
Step-by-step explanation:
Answer:
not the matrix equation but this works
x=4, y=1
Step-by-step explanation:
2x-4y=4 (original equation)
2(3x+2y=14) (do this so that you can subtract or add- it's still equal)
2x-4y=4 (original equation)
6x+4y=28 (after multiplying)
8x=32 (add 2 equations together to cancel out 4y, can also subtract)
x=4 (division)
2(4)-4y=4 (substitution)
8-4y=4 (multiplication)
4y=4 (addition/subtraction)
y=1 (division)
