230 divided by 12 1/2 is 18.4. 18.4 times the width is 230. so the length is 18.4.
Answer:
(6, -9)
Step-by-step explanation:
Our system of linear equations is:
6x + 2y = 18
-4x - 2y = -6
When we solve by elimination, we're essentially "eliminating" a variable so that we can solve for other more easily. Here, let's eliminate the y variable by adding the two equations together:
6x + 2y = 18
+ -4x - 2y = -6
____________
2x + 0y = 12
x = 12/2 = 6
Plug this back into one of the original equations to find y:
-4x - 2y = -6
-4 * 6 - 2y = -6
-24 - 2y = -6
-2y = 18
y = -9
The solution is (6, -9).
The answer to the first question is the square root of five, the second answer choice.
The answer to the second question, I'm not 100% certain but I'm pretty sure its 2^0, the first answer choice or 2^1, the second answer choice. Take your pick.
