Question

Jill is thinking of a number. Four more than three times the number is thirteen. What is the number?
Jill’s number is ____
(1.8)
(2.3)
(3)
(4)

Answer 1

Let's solve the problem step by step:

Let's assume Jill's number is x.
According to the given information, "Four more than three times the number is thirteen", we can write this as an equation:

4 + 3x = 13.

Now, subtracting 4 from both sides of the equation:

3x = 13 - 4,
3x = 9.

Finally, divide both sides of the equation by 3 to solve for x:

x = 9/3,
x = 3.

Therefore, Jill's number is 3. So, the correct answer is (3).
