<span>The equation that can be used is 90-10y=5x. In order to get this answer, you first start with figuring out how many miles total were hiked for each trail. The 5-mile mountain trail total would be equal to 5x and the 10-mile canal trail total would be 10y. Adding both of these totals together would give you 90 miles and an equation of 5x+10y=90. All you do now is rearrange the equation by subtracting 10y from each side and you get 90-10y=5x.</span>
Answer:
2sqrt(5)+11
Step-by-step explanation:
f(x)=sqrt(x)+11
f(20)=sqrt(20)+11
f(20)=sqrt(4*5)+11
f(20)=sqrt(4)*sqrt(5)+11
f(20)=2*sqrt(5)+11
