If you would like to solve the system of equations x + y = 3 and 2x - y = 6, you can do this using the following steps:
<span>x + y = 3 ... y = 3 - x
2x - y = 6
</span>_________
<span>2x - y = 6
</span>2x - (3 - x) = 6
2x - 3 + x = 6
3x = 6 + 3
3x = 9 /3
x = 9/3
x = 3
<span>y = 3 - x = 3 - 3 = 0
</span>
The correct result would be x = 3.
Answer:
350
Step-by-step explanation:
All you have to do is:
Multiply the fraction 7/10 by 500=350
-19.2
12/(-5/8) means 12*(-8/5)
12*8=96
96/5=19.2
don’t forget the negative sign
so
-19.2
Answer:
The Slope of both the lines is the same.
Step-by-step explanation:
Given two co-ordinates (x1, y1) and (x2, y2), the slope of a line can be found using the formula:

For the diagonal line of the first triangle, the coordinates are (0, 0) and (2, 1)

For the diagonal line of the large triangle, the coordinates are (2, 1) and (6, 3)
