Question

A rational number is such that when you multiply it by 52 and add 23 to the product, you get 712. What is the number?

a) 12
b) 14
c) 16
d) 18

Answer 1

The rational number is 13.

Step-by-step explanation:

We are given that when we multiply a rational number by 52 and add 23 to the product, we get 712.

Let's assume the rational number is x.

Therefore, we can write the equation as 52x + 23 = 712.

To solve for x, we need to isolate x on one side of the equation.

Subtracting 23 from both sides, we get 52x = 689.

Finally, dividing both sides by 52, we find that x = 13.

Therefore, the rational number is 13.
