is 5.676677666777 a rational number? ( please just a yes or no and please explain is easy terms, i'm stupid. )

Yes.

Step-by-step explanation:

Im pretty sure about this but there's the possibility that I'm wrong.

A number that can be changed into a fraction is a rational number.

So any decimal that terminates (Ends) or repeats (has the same numbers forever.) are in fact rational numbers.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
