Not A because:
(Subtract 11 from both sides)
4n > -20
(Divide both sides by 4)
n > -5
Because we have found that dividing the negative number by 4 does not work, we know B is also wrong.
Not C because:
(Subtract 11 from both sides)
-4n < -20
(Divide each side by -4)
(Reverse inequality sign because you are dividing by a negative number)
n > 5
So, it must be D!
Here's why:
(Subtract 11 from both sides)
-4n > -20
(Divide each side by -4)
(Reverse inequality sign because you are dividing by a negative number)
n < 5
Hope this helps!
Answer:she will earn $200 in 5 weeks
Step-by-step explanation:
Susan takes care of a child for 2 hours after school each weekday and 6 hours on Saturday. There are 5 school days in a week. Total number of hours that she spends in taking care of the child during the weekdays would be 5×2 = 10 hours.
Total hours for the week would be
10 + 6 = 16 hours
Total amount of hours in 5 weeks would be
5 × 16 = 80
If she earns 2.50 per hour, it means that in 80 hours, she would earn
2.5 × 80 = $200
