Answer:
eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
3x + 6 >=0 that's the equation and yes it would be greater
16x +23
-16 -16
X = 7....................
Answer:
C
15 + x
Step by step explanation
For Company X, the initial cost is 30 cents plus 5 cents per minute, so the expression would be 30 + 5x (x would represent minutes.
For Company Y, the initial cost is 15 cents plus 4 cents per minute, so the expression would be 15 + 4x (x would represent minutes.)
Then subtract the expression of Y from the expression of X to show the difference in value between Y and X.
So, 30 + 5x - (15 +4x)
Distribute the subtraction sign.
30 + 5x - 15 - 4x
Solve across.
15 + x
4x-5=31
Add 5 to both sides
4x=36
Divide both sides by 4
x=9
Final answer: 9
