Answer 1

Let's denote the unknown number as \( x \). According to the problem statement, we can set up the equation:

\[
10(x + (-1)) = -40
\]

This simplifies to:

\[
10(x - 1) = -40
\]

Now, we can divide both sides by 10:

\[
x - 1 = -4
\]

Next, we can solve for \( x \) by adding 1 to both sides:

\[
x = -4 + 1
\]

\[
x = -3
\]

So, the number is \(-3\).

The correct response is:

**−3 (negative 3)**.
