Step 1
(r+4-2r-14)>0 equation/Question
Step 2
(r+4-2r-14)>0 Simplify to remove parenthesis
-r-10>0
Step 3
-r-10>0 Add 10 to sides
-r-10+10>0+10
-r>10
Step 4
-r/-1>10/-1 cross multiply (which also means divide)
answer
r<-10
Answer:
- <u><em>Option A: 500 pages</em></u>
Explanation:
<u>1. Number of pages of the first 5 novels</u>
- Average = [Number of pages] / [number of novels]
- 450 pages / novel = Number of pages / 5 novels
- Number of pages = 5 novels × 450 pages / novel = 2,250 pages
<u>2. Average length of all 6 novels</u>
- Average = [Number of pages] / [number of novels]
- Number of pages of 6 novels = 2,250 pages + 750 pages = 3,000 pages
- Average = 3,000 pages / 6 novels = 500 pages / novel
An octagonal based pyramid.
Unless you meant faces including the base in which case it is a heptagonal based pyramid.
Hope this helps :)
Answer Z=2
The math …..
Multiple ( ) first
15z -21 -18z +22 = 32z - 52 -17
Combine like terms
-3z + 1 = 32z -69
Move like terms to isolate Z
-35z = -70 two negative make positive
35z = 70
Divide both sides by 35 to isolate Z
Z = 2
