Answer:
The number is 19
Step-by-step explanation:
7 less than a number = x - 7
2x - x - 7 = 12
Subtract x from 2x
x - 7 = 12
Add 7 to both sides of the equation
x = 19
The number is 19

2.7 is a rational number because it's a terminating decimal which means that the decimal does end and all terminating decimals are rational numbers.
-3 is a rational number because it's an
integer and all integers are rational.
√4 is rational because it's a perfect square which means that a number can be multiplied by itself to get 4 and that number is 2.

non-terminating and non-repeating.
