Answer:
x = 2.8
Step-by-step explanation:
Hey!!!
We've pretty much simplified the equation, and we're on the last step!
To find what x is, we need to divide 2/5 by 7.
I've put it in some LaTeX:
[tex]\frac{2}{\frac{5}{7}}[/tex] = x
2 ÷ [tex]\frac{5}{7}[/tex] = x (The viniculum in a fraction represents division.)
2 × [tex]\frac{7}{5}[/tex] (Division is the same as multiplication by the reciprocal.)
[tex]\frac{14}{5}[/tex] = x
[tex]\frac{14}{5}[/tex] = 2 [tex]\frac{4}{5}[/tex] = 2.8
Thus, the answer is [tex]\boxed{x = 2.8}[/tex].
Check:
2.8 ÷ 7 = 0.4 = 2/5
So, we are correct!
