$8.30?
I need more info, is this including tax or are you having to tax the items as well?
Answer:
Step-by-step explanation:
To prove: The sum of a rational number and an irrational number is an irrational number.
Proof: Assume that a + b = x and that x is rational.
Then b = x – a = x + (–a).
Now, x + (–a) is rational because addition of two rational numbers is rational (Additivity property).
However, it was stated that b is an irrational number. This is a contradiction.
Therefore, the assumption that x is rational in the equation a + b = x must be incorrect, and x should be an irrational number.
Hence, the sum of a rational number and an irrational number is irrational.
It’s prob 20 or 30 Bc 18 is rounded to 20 and 29 is rounded to 30
I would say read it well and then write down an equation or expression to represent the data so its easier for you to understand and/or solve.
