In this question, the thing that needs to be found is the number whose 20% would be 18. The information's required for getting to the solution are already provided in the question. based on those given information's, the answer can be deduced very easily.
Let us assume the unknown number to be = x
Then
(20/100) * x = 18
x/5 = 18
x = 18 * 5
= 90
so the unknown number in the question is 90. I hope the procedure is clear enough for you to understand.

We have a proportion: 18/?= 20/100

Cross multiply:
20*?= 18*100
⇒ ?= 18*100/20= 90

20% of 90 is 18~

Consider a system of two linear equations in two variables. If the graphs of the equations are not the same line, is it possible

FinnZ [79.3K]

Answer:

Step-by-step explanation:

Solutions to systems of equations are points at which the lines of the equations intersect. Knowing this, only equations representing the same line would have infinitely many solutions because they would intersect at every one of each other's points - they're the exact same line. Therefore, if they are not the same line, they would not intersect at each and every point, and would not have infinitely many solutions.
