Is this sum rational or irrational? Explain. 1.12 + 18/7 (1 point)

The sum is rational because both 1.12 and 18 are rational, and the sum of rational numbers is rational.

The sum is irrational because 1.12 is irrational, and the sum of a rational number and an irrational number is irrational..

The sum is rational because both 1.12 and 18 are positive, and the sum of positive numbers is rational.

The sum is irrational because 18 is irrational, and the sum of a rational number and an irrational number is irrational.

First

"The sum is rational because both 1.12 and 18 are rational, and the sum of rational numbers is rational."

Step-by-step explanation:

Both 1.12 and 18/7 are rational numbers (meaning that they can be written as a quotient of integer numbers:

1.12 = 112/100

Then, since the addition of rational numbers is also a rational number, their sum is another rational number.

Then the correct answer is:

The sum is rational because both 1.12 and 18 are rational, and the sum of rational numbers is rational.

step-by-step explanation:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
