Final answer:

Julio's number is 20.

Step-by-step explanation:

To find Julio's number, we can set up an equation based on the information given.

Let's call Julio's number 'x'.

So, the equation would be: (x - 12) * -5 = -40.

To solve for x, we need to isolate it. We can start by dividing both sides of the equation by -5 to get: x - 12 = 8.

Next, we can add 12 to both sides to get: x = 20.

Therefore, Julio's number is 20.

Answer:

Julio's number is 212

Step-by-step explanation:

(x - 12) ÷ -5 = -40

x - 12 = -40 times -5

x - 12 = 200

x = 200 + 12

x = 212

Check:

(x - 12) ÷ -5 = -40

((212 - 12)) ÷ -5 = -40

200 ÷ -5 = -40

-40 = -40
