Answer:
Answer given below
Step-by-step explanation:
When we calculate the LCM, you get it as 6.
So both the fractions should have a denominator 6.
For that, in 2/3 we should multiply both numerator and denominator with 2 so that denominator becomes 6.
When we convert to like fraction, 2/3 becomes 4/6.
Now both the fractions have common denominator
Hope it helps.
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
Answer:
slope = 2
Step-by-step explanation:
The ordered pairs are (2,3) and (5,9).
It is given that the function is linear.
Since it is linear, the graph of the function is a straight line.
Slope of the straight line is constant at all points lying on it.
Slope of a straight line containing the points
and
is given by:
.
Slope of the straight line containing (2,3) and (5,9) is given by:
.
