Linda had 42 fliers to post around town. last week, she posted 2/3 of them. this week she posted 5/7 of the remaining flires. how many fliers has she still not posted?

4

Step-by-step explanation:

Last week she posted 2/3 of the 42 fliers.  This means she posted (2/3)*42 fliers.

(2/3)*42

84/3

28

So she posted 28 last week.

So of the 42, 42-28=14 remain

This week she posted 5/7 of the remaining fliers.

So she posted 5/7 of the 14 that remainder. This means she posted (5/7)*14 fliers.

(5/7)*14

70/7

10

So she posted 10 this week.

So of the 42, 42-28-10=4 remain.

She hasn't posted 4 fliers.

answer:   n ≤ -3 or n < -5

step-by-step explanation:

-5 + 2n ≥ -11

+5             +5

2n ≥ -6

2/2 ≤ -6/2

n ≤ -3

-6 - 10n > 44

+6           +6

-10n > 50

-10/-10 50/-10

n < -5

42
