Step-by-step explanation:
y=2.78(4)-4.4 = 6.72
Answer:
the second one is the right answer (2)
Use substitution and substitute y into the other equation. One of the equations already gives you y in terms of x, so use that and substitute it into the other equation. y = 3x - 4
Plug into the other equation: -3y = -9x + 12
-3(3x-4) = -9x + 12
-9x + 12 = -9x + 12
This is an identity. So that means that any value of x makes this equation true. So B.
total 22 marbles, green and white ones are 5 so 22-5=17 so 17/22 or 17 out of 22
