+124 For a tile pattern with the rule y=6x+4 (where x represents the figure number and y repesents the number of tiles), which figure number has 40 tiles in it? How do you know?

+1667 Hey, cool. I'm in 7th grade, too.
We're working on two way tables, right now. We just finished regression lines, residual plots, etc.
+71 Seriously? I am in 7th and i am doing stuff like 5 times more complicated :P
Well i guess thats because im going to a special school thats teaching high school stuff
the answer is x=6

When we plug in 40, we have...
40=6x+4
First, let's subtract 4 from each side.
40-4=36
4-4=0
Now we have...
36=6x
Divide by 6 on each side to make the right side x.
36/6=6
6x/6=x
6=x
In conclusion, figure no. 6 has 40 tiles in it.
