Answer Z = -1/4
Step-by-step explanation:
-1/3+2z= -5/6
Add 1/3 to both sides
-1/3+2z+1/3 = -5/6+1/3
Simplify
2z=-1/2
Divide both sides by 2
2z/2 = -1/2/2
Simplify
z = -1/4
If you gave away 280 of 600 business cards and you would like to know what percent of the cards is left, you can calculate this using the following steps:
600 - 280 = 320 cards are left
320 / 600 = 8 / 15 = 0.5333 = 53.33%
The correct result is D. 53.33%.
