Answer:
C. 9
Step-by-step explanation:
Ron is five years older than twice his cousin's age. Lets assume that Pat's age is 'x' years.
So Ron's age is [tex]2\times x+5=2x+5[/tex]
The question says:
[tex]x+2x+5<35[/tex]
[tex]3x+5<35[/tex]
[tex]3x<35-5[/tex]
[tex]3x<30[/tex]
[tex]x<10[/tex]
Pat's age [tex](x)[/tex] should be less than 10. Therefore, the greatest age (in integer) that Pat can be is 9 years.
