Option A.
Answer:
u = (sa) + k
Step-by-step explanation:

The number of snail shells used is 45 and the number of shark teeth used is 36 if the ratio of snail shells to shark teeth is 5:4.
According to the question,
We have the following information:
A jeweler makes an ocean-inspired necklace using a total of 72 snail shells and shark teeth. The ratio of snail shells to shark teeth is 5: 4.
Let's take the number of snail shells to be 5x and the number of shark teeth to be 4x.
So, we have the following expression:
5x+4x = 72
9x = 72
x = 72/9
x = 8
Number of snail shells = 5*9 = 45
Number of shark teeth = 4*9 = 36
Hence, the number of snail shells used is 45 and the number of shark teeth used is 36 if the ratio of snail shells to shark teeth is 5:4.
