Answer:128
Step-by-step explanation:
y+yx
When x=15, y=8
8+(15×8)
=8+120=128
Answer:
S = ( 6, 12, 18, 24, 30, 36......)
T = ( 2, 4, 6, 8, 10, 12, 14, 16, 18......)
We know that the variation is proportianal, that is we can relate the quantities as:

where y is the mass of the body and x is the mass of water. From the values given we have that:

hence the constant of proportionality is 3/2. Now, if the mass of the water is 75, then the mass of the body is:

Therefore, the mass of the body is 112.5 kilograms
The first one, 1/8, 3/16, and 3/4, are from least to greatest.
