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.
(2x^2+6x-11)-(5x^2-x+7)
Pretend that there is a -1 in front of the second bracket
-1(5x^2-x+7)=-5x^2+x-7
2x^2+6x-11-5x^2+x-7
2x^2-5x^2+6x+x-11-7 ( combine like terms)\
-3x^2+7x-18
Answer: d. -3x^2+7x-18
