r = sqrt(10) = sqrt(10) sin(0) = y/r = 1/sqrt(10) = (cos(0))/sqrt(10) = x/r = -3/sqrt(10) = -(3 tan(0))/sqrt(10) = y/x = -1/3.</span>
Answer:
12 over 4
Step-by-step explanation:
You divide 12 by 3 which equals 4 so if you were making 3 equal teams 12 over 4 would equal 3
Answer:
12
Step-by-step explanation:
Answer:
x = -6, y = -2
Step-by-step explanation:
2x-7y = 2
3x + y = -20
We need to cancel out either x or y to solve the equation. I'll cancel out x first
3(2x-7y = 2)
-2(3x+y=-20)
___________
6x-21y = 6
-6x -2y = 40
____________
-23y = 46
y = -2
Plug the value for y in one of the 2 equations to solve for x
2x -7(-2) = 2
2x+14=2
2x = -12
x=-6
