yes it is true that a linear system of three equations with two variables is inconsistent because when we solve the equations variables can be obtained by only first two equations which are considered first. and third equation is useless.

Y = 0.27x<br> What is the constant of proportionality?

umka21 [38]

Hey!

------------------------------------------------

The constant of proportionality is 0.27!

We could write a word problem for this. Like:

Jared had paid $0.27 for one pencil. How much would it cost to buy 5 pencils?

0.27 x 1 = $0.27

0.27 x 2 = $0.54

0.27 x 3 = $0.81

0.27 x 4 = $1.08

0.27 x 5 = $1.35

We can see that if Jared bought 5 pencils for $1.35. Since the proportionality is 0.27 just multiply how many times you need to.

We could also write this as: $\frac{0.27}{1}$

------------------------------------------------

Hope This Helped! Good Luck!
