Answer:
4h + 100
Step-by-step explanation:
h = total number of hats
postcards = 2h
magnets = h + 100
Add them all together:
h + 2h + h + 100 = 4h +100
Hey there,
1 week = $11
15 weeks = $ 11 x 15
= $165
Hope this helps :))

Answer:
(-∞, -7) ∪ (-3, ∞)
Step-by-step explanation:
The line y=0 is the x-axis. The graph is above the x-axis for x < -7 and for x > -3. The solution set is ...
(-∞, -7) ∪ (-3, ∞)

Answer: x > 2</h3>
Work Shown:
5x - 14x < - 18
-9x < - 18
x > -18/(-9)
x > 2
The inequality sign flips when dividing both sides by a negative number.
Here's another approach you could take.
5x - 14x < - 18
-9x < -18
0 < -18+9x
18 < 9x
9x > 18
x > 18/9
x > 2
It's a slightly longer pathway, but it avoids a sign flip when you divide both sides by the positive number 9.
The sign flip happens two steps earlier when going from 18 < 9x to 9x > 18. In other words, A < B is the same as B > A.
