Step-by-step explanation:
An integer is like a whole number (28 is an integer).
Irrational means the decimal goes on forever.......and cannot be written as a fraction (0.9857... is irrational).

A rational number can be written as a fraction (like 8 and 1/7).
Answer:
4.77 cm correct to the nearest hundredth.
Step-by-step explanation:
The new circumference = 19 - 4 = 15 cm.
Circumference C = π * diameter
So the diameter = C/π = 15/π = 4.7746 cm
The first step was the combine the like terms; in this example he is subtracting the 3x on both sides of the =.
If you were to solve the equation it would look like this:
2x+6=3x-8
-3x -3x
-x+6=-8
-6 -6
-x=-14
/-1 /-1
x=14
5 · (6 - 1) + 3
= 5·5 + 3
= 25 + 3
= 28
