Thirteen more than four times a number is at least -93
Let's call the number "x".
The statement "thirteen more than four times a number" can be written as 4x + 13.
According to the problem, 4x + 13 is at least -93, which can be written as the inequality: 4x + 13 ≥ -93.
To solve this inequality, we will subtract 13 from both sides:
4x + 13 - 13 ≥ -93 - 13
4x ≥ -106.
Finally, we will divide both sides by 4 to solve for x:
(4x)/4 ≥ (-106)/4
x ≥ -26.75.
So the number "x" is greater than or equal to -26.75.
