Answer:
because either x-6=0 or x+1=0
x-6=0
x=0+6
x=6 OR,
x+1=0
x=0-1
x=-1
Step-by-step explanation:
Answer: option D is the correct answer.
Step-by-step explanation:
Let m represent the total number of minutes that the phone is used in a month.
Let C represent the amount of the bill for using m minutes.
His monthly bill will be $32.99 each month which includes 100 minutes of use. Additional minutes will cost $0.19 per minute. It means that the cost of additional minutes is
0.19(m - 100). Therefore, the linear model representing the amount of the bill would be
C = 0.19(m - 100) + 32.99
She makes 3 hats per 1 and 1/2 hours. Therefore she makes

hats per hour. This fraction simplified is 2 hats per hour. This is the solution.
2 hats per hour.
Subtract 8 from both sides
So you end up with x = -23
7/8+(−2/3) divided by 5/6
(7/8 - 2/3)/(5/6)
=(21/24 - 16/24) / (5/6)
= (5/24) / (5/6)
= 5/24 * 6/5
= 6/24
= 1/4
