Answer:
136 minutes
Step-by-step explanation:
The amount that Joe pays is in two parts. He pays a definite amount for the month plus the amount per minute charge.
Thus,
Joe's monthly fee = $3 + $0.11n
where n is the number of minutes.
Joe's bill for the month = $17.96
So that,
$17.96 = $3 + $0.11n
$17.96 - $3 = $0.11
14.96 = $0.11n
n =
= 136
The number of minutes that Joe was billed is 136.
In this case, Joe was billed for 136 minutes for the month.

Answer:
5x + y = 3/8
Step-by-step explanation:
Add to both sides
+ y = 3
Divide both sides by 8
5x + y = 3/8
So we have to simplify this equation:
4x+5-10+3x=57
Add like terms:
7x-5=57
Then add 5 to both sides:
7x=62
x=62/7
Step-by-step explanation:
2x^3 -9x^2 +11x-6 divided by x-3
We use long division
2x^2 - 3x + 2
------------------------------
x - 3 2x^3 - 9x^2 + 11x - 6
2x^3 - 6x^2
--------------------------------------(subtract)
-3x^2 + 11x
-3x^2 + 9 x
----------------------------------------(subtract)
2x - 6
2x - 6
-----------------------------(subtract)
0
Quotient : 2x^2 - 3x + 2
