Answer :
The number Joe is thinking of is -36.
To find the number Joe is thinking of, use algebraic expression and equation.
Let x be the number Joe is thinking of
According to the problem, "Eleven more than one third of the number is -1". We can translate this into an algebraic expression such as:
x/3 + 11 = -1
To find the value of x, we'll isolate it on one side of the equation:
x/3 = -12
Next, we'll multiply both sides of the equation by 3 to cancel out the fraction:
x = -36
Therefore, the number Joe is thinking of is -36.
