Here is how to work the problem... basically you solve for one of the variables in one of the problems and then use substitution into the other. once you have both answers you substitute them both Into the last equation to solve.
Simplify 5a-2(-3a +b).

Answer:
Constant of variation is 24.
Step-by-step explanation:
Inverse variation states that a relationship between two variables in which the product is remain constant.
If one variable increases then, the other one decreases in proportion so that the product is unchanged,
if y is inversely proportional to x i.e or
;where k is the constant of variation.
It is given that 3 identical water pumps takes 8 hours to fill a pool,
since, it will take less time with more pumps, so it is an inverse variation.
By definition of inverse variation;
Substitute the values to solve for k;
Multiply by 3 to both sides we get;
Simplify:
k = 24
Therefore, the constant of variation is, 24
Answer:
Labels did she print is 36.
Step-by-step explanation:
Given : Ms kaimal prints out address labels on 3 sheets of paper each sheet is entirely covered in labels each label takes up of a sheet.
To find : How many labels did she print ?
Solution :
of a sheet takes up 1 label.
So, 1 of a sheet takes up label.
1 of a sheet takes up 12 label.
Then, 3 of a sheet takes up label.
3 of a sheet takes up 36 label.
Therefore, Labels did she print is 36.
