Answer:
D. The number could be 1,2,3,4,5,6 or 7.
Explanation:
Let the number = n
Twice the number = 2n
Five more than twice a number = 2n+5
If the expression above is less than 20, we have:
[tex]2n+5<20[/tex]
We solve for n.
[tex]\begin{gathered} 2n<20-5 \\ 2n<15 \\ n<\frac{15}{2} \\ n<7.5 \end{gathered}[/tex]
Since n is less than 7.5, the number could be 1,2,3,4,5,6 or 7.
