Answer:
s = 4
Step-by-step explanation:
3r = 10 + 5s
3×10 = 10 + 5s
5s = 30 - 10
5s = 20
s = 20 : 5
s = 4
......,.... the answer is h= -5
Assume the missing sequence is x
so -1536 / 384 = x / 24
so x = (24* - 1536) / 384
so x = -96
the answer is C. -96
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.
