Answer:
-2.64
Step-by-step explanation:
Answer:
im pretty sure it is 113.
Step-by-step explanation:
OK first convert one of the equations into Y=MX+b form
Y-2x = 3
Add 2X
Y = 2x +3
Now substitute this equation in the other one.
So it would be
3X - 2Y = 5
3X-2(2x+3) = 5
Now solve for y
3X - 4X - 6 = 5
-1X - 6 = 5
Add 6
-1X = 11
X = -11
Now substitute this into one of the equations
Y - 2X = 3
Y -2(-11) = 3
Y +22 = 3
y = 3-22
y = -19
You have to find 80% of 20.
Since 80% is equal to 0.8, you multiply 20 by 0.8 to get 16
