7*10=70 millimeters
1 cm=10 mm
6+2=8, right? Okay. Next, all you have to do is take away the equation "6+2". Now what you have is... 8x5. That's easy! 40. This is a very easy problem if you think about it.
Answer:
BD is 2x1
CA is 2x1
BC is 2x3

Step-by-step explanation:
Answer:
Step-by-step explanation:
9/2 / 8/3
9/2 x 3/8
27/16 = 1 13/16
You can use the process elimination to solve. In other words, subtract or add the equations like normal.
5x + 2y = -15
+ 2x - 2y = -6
Because there is a 2y and -2y, we can add both equations to eliminate the y so that we can figure out what x is:
5x + 2x = 7x
2y + (-2y) = 0
-15 + (-6) = -21
We now have 7x = -21
Divide all by 7 to get x = -3
Plug in -3 to any of the two equations. I will use the second equation:
2(-3) - 2y = -6
-6 - 2y = -6
-2y = 0
y = 0
This means that the solution to the system of equations is (-3, 0) in the form of (x, y).
