280,706 is the standard form
So to do this, we have to get rid of one of the variables by adding or subtracting the two equations together.
I will get rid of y. So, we can multiply the second equation by 2. This gives us
2x-2y=10
Now, we can add both equations
This gives us 7x=-14
Therefore, x = -2
Plug that into another equation.
-10 + 2y=-24
Therefore, y = -7
Hope this helped!! :D
Answer:
4
Step-by-step explanation:
Well, from what you’ve posted, it seems that a negative value cannot be accepted since that would imply she has gone underwater. She also cannot go above 300 feet since she is going downwards from a max height.
10x - 4.5 + 3x = 12x - 1.1
13x - 4.5 = 12x - 1.1
13x - 12x - 4.5 = 12x - 12x - 1.1
1x - 4.5 = -1.1
1x - 4.5 + 4.5 = -1.1 + 4.5
1x = 3.4
X = 3.4
