Question

Answer 1

\(1-\left(\dfrac{9}{8}:\dfrac{21}{8}+\dfrac{1}{7}\right)< \dfrac{x}{35}< \dfrac{2}{7}\times2+\dfrac{2}{35}\times\dfrac{5}{2}\)
\(1-\left(\dfrac{3}{7}+\dfrac{1}{7}\right)< \dfrac{x}{35}< \dfrac{4}{7}+\dfrac{1}{7}\)
\(1-\dfrac{4}{7}< \dfrac{x}{35}< \dfrac{5}{7}\)
\(\dfrac{3}{7}< \dfrac{x}{35}< \dfrac{5}{7}\)
\(\dfrac{15}{35}< \dfrac{x}{35}< \dfrac{25}{35}\)
\(x=16;17;18;19;20;21;22;23;24\)
Số của các số nguyên thỏa mãn là:
\(\left(24-16\right):1+19\left(số\right)\)
