You use substitution to solve a system of equations and, after simplifying the equations, end with an expression that says 0=4. What does that say about the lines and about the number of solutions to the system?

Step-by-step explanation:

That says the system is "inconsistent", so the lines are parallel, and the number of solutions is zero.

The attachment has an example of such a system.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
