Example 1: Solve the system of equations by elimination
Elimination Method Example
Solution:
In this example we will "cancel out" the y term. To do so, we can add the equations together.
Elimination Method Solution
Now we can find: x = 2
In order to solve for y, take the value for x and substitute it back into either one of the original equations.
Elimination Method Solution
The solution is (x, y) = (2, 1).
Answer:
1. 15
2. 26.6666666667
3. 26.6666666667
4. 15
5. 8
Step-by-step explanation:
H= L(leg) * radical 2
So therefore 9 radical 2 (or your given number) *(times/ multiply by) radical 2 is or = 9 radical 4
Just multiple both radical numbers ;)
If she answered all then she would have gotten 179 wrong. If I understand 200 questions and 11% on the test then 179 wrong and 21 right. So if you are asking how many she did not answer I would assume the questions she got wrong were the questions she did not answer which would be 179.
