Answer:
The solution is (0, 3/4)
Step-by-step explanation:
Please copy and share the instructions. Here they are: Solve the following system of linear equations.
Both of the equations can be reduced (simplified):
2x+8y = 6 => x + 4y = 3
15x + 20y = 15 => 3x + 4y = 3
Let's use the elimination by addition and subtraction method. Multiply the first equation by -1, obtaining
-x - 4y = -3
Add the second 3x + 4y = 3
equation to the
first.
We get: 2x = 0.
Thus, x = 0. Substituting 0 for x in the 1st original equation yields:
2(0) + 8y = 6. Then y = 6/8, or y = 3/4.
The solution is (0, 3/4).
Answer:
11, 17, and 28.
Step-by-step explanation:
Lowest number is 
Median is 
Highest number is 
X-9=8(2x+3)-18
x-9=16x+24-18
-9=15x+6
-15=15x
x=-1
15.69 because 49.57-2.50 divided by 3 =15.69
486/6=81
Square root 81 = one side length = 9m
volume = 9^3 = 729
