Answer:
15 jewelry sets
Step-by-step explanation:
66 and 2/3 in a fraction would be 200/3 n lowest terms
You have to multiply 200 by 3 and add 2 to get 200
66 and 2/3 in a decimal would be 66.67
Divide 2/3 to get .67 and add 66.
Plug in x=1 and y=2 into the inequality:-
2x + 9y = 2 + 18 = 20
20 is not < 20
so it is not a solution
