Answer:
<h3>Add to eliminate y.</h3>
Step-by-step explanation:
Given the equations
-9x + y = 71.... 1
-x - y = -1 .... 2
Using elimination method we can eliminate y first since they have the same coefficient.
To do that we will need to add up both equations. We are adding because the coefficient of y in both equations has different signs. If they have the same sign, we would have subtracted.
<em>Hence the correct option in this case is to add to eliminate y.</em>
Answer:
Day 3 : 6 Day 2: 4 Day 1: 2 and so on
Step-by-step explanation:
This may not be correct but i think that you multiply the day number by two.
The angles inside a trapezoid add up to equal 360 degrees
X = 360-90-90-75 = 105 degrees.
the answer is 1/8. I double checked
