Answer:
Kelvin’s error is that when he got the final result, that was the amount that was marked down. He still needed to find the price after the original price was marked down by that number wich in this case is $18.39. So using one of his steps, 30.65(0.6)=18.39. We can subtract 30.65 (original price) and 18.39 (mark down price). You’d get 11.26 dollars as the final price.

Answer:

Step-by-step explanation:
LCD: 10

answer: 
Step 1: You can distribute it by multiplying 6 by 2x and -12, so you get 12x-72= 24
Step 2: Now you can solve it by adding 72 on both sides, so we get 12x= 96, then you can divide 12 on both sides, so we get x=8.
