Three less than 5 times a number is less than or equal to 12 . If the number is a whole number, what could the number be?

Answer:
B. The number could be 1, 2 or 3.
Explanation:
Let the number = x
• 5 times the number = 5x
,• Three less than 5 times a number = 5x-3
If the expression above is less than or equal to 12, we have:
[tex]5x-3\le12[/tex]We solve for x.
[tex]\begin{gathered} 5x\le12+3 \\ 5x\le15 \\ x\le\frac{15}{5} \\ x\le3 \end{gathered}[/tex]Since the number is less than or equal to three, the number could be 1, 2 or 3.
