200 books x 30 boxes = 6000 books
6000 books x 20 shipping crates = 120,000 books
Just keep multiplying
If 90% of bodies are water weight, then we have 10% left.
76+10% = 83.6.
83.6 total.
z = -11
Steps:
8z+12 = 5z-21
Subtract 12 from both sides
8z+12-12 = 5z-21-12
Simplify
8z = 5z-33
Subtract 5z from both sides
8z-5z = 5z-33-5z
Simplify
3z = -33
Divide both sides by 3
3z/3 = -33/3
Simplify
z = -11
Hope this helps you! (:
