Answer:
x = 9
Step-by-step explanation:
The question is shown in the attached figure.
We can see that, (8x + 5)° and (13x – 14)° forms a linear pair. It would mean that,
(8x + 5)° + (13x – 14)° = 180°
21x-9 = 180°
21x = 180° + 9
21x = 189
x = 9
Hence, the value of x is 9.
The answer would be $24.55 per oz of gold alloy so rounded up would be $25
