Is 12.89 irrational

1 answer:

7 0

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.

3x-4 = -10

3x-4 +4 = -10 +4

3x = -6

then you can divide it :

x = -6 : 3

x= -2

Please help I need to know the rule in correspondence to the pattern?

trasher [3.6K]

You can see that an odd number of steps is simply multiplying the number of steps by a number that moves up one each time. For instance, 1*1, 3*2, 5*3, etc. It's a bit harder with the even numbers. Their pattern is multiplying half the number of steps by 1.5, but the ones place value moves up a number each time, for example, 2*1.5, 4*2.5, 6*3.5. This means that 10 steps is 10 * 5.5, or 55 blocks and that 100 is 5,050 steps.
