Answer: 8

Step-by-step explanation: Because a is perpendicular to b, the value of 9x + 18 = 90.  If we subtract 18 from both sides, it becomes 9x = 72.  Divide by 9 on both sides to get 8

Is 12.89 irrational
STatiana [176]

No.  It's the ratio of  1,289  to  100 .

Also, it can be written as a fraction with whole numbers
on top and bottom, like this:    1289 / 100 .

Also, it can be written down on paper completely, using
digits and a decimal point or fraction bar.  (You did that.)

Any one of these three facts makes it a rational number.
