Answer: She misses 56 times at a soccer practice.
Step-by-step explanation:
Let the goals she misses be 'x'.
According to the question:
[tex]5:8::35:x[/tex]
These two ratios follow direct relationship, so:
[tex]\frac{5}{8}=\frac{35}{x}\\\\5x=35\times 8\\\\x=\frac{280}{5}\\\\x=56[/tex]
Hence, Vonna misses 56 times at a soccer practice.
