C is your answer because you count 1 square a block
The answer you be five. If you take the twenty tokens and divide them into groups of four, you will find that you are left with five groups of tokens. Each group of tokens represents an hour of parking time. This will give you five groups, or five hours, total.
The correct answer is Geometric sequence, Fibonacci sequence, and Arithmetic sequence. I just turned my class where I had this question and my teacher said I got them right. hoped this helped :)
We have a system of equations 2x - 4y = 5 and 6x - 3y = 10.
We want to eliminate one variable when we add up the equations.
If we want to eliminate the x variable, we need to multiply the top, bottom or both of the equations with a number that when the equations are added together will eliminate the x variable.
Multiply the top equation by -3.
-3(2x - 4y) = 5 * -3
-6x + 12y = -15
Now when we add the two equations together, the x's will be eliminated.
-6x + 12y = -15
6x + 6y = 10
18y = -5
The x's were eliminated.
