the answer is Zero
four minus four equals zero
Step-by-step explanation:
2x-y=8
x+y=20
------------
3x=28
×=28÷3=9.3
so
9.3+y=20
y=20-9.3
y=20.7
1/3 is equal to 3/9. The answer is 3.
Vertex form: y = (x + 1)^2 - 25
vertex: (-1, -25)
10(c + 5) = 125
10c + 50 = 125
subtract 50 from both sides of the equation
10c = 75
divide 10 from both sides of the equation
c = 7.5
