ad-work [718]

Answer:

77.7 miles.

Step-by-step explanation:

We have been given that Louis has already biked 17.7 miles this week. He can bike 6 miles in one hour. Let the total biked be represented by d and let the number of hours biking be represented by h. an equation that represents this scenario is: $d=6h+17.7$ .

To find total number of miles Louis biked in 10 hours we will substitute 10 in place of h in our given equation.

$d=6*h+17.7$

$d=6*10+17.7$

$d=60+17.7$

$d=77.7$

Therefore, number of total miles biked will be 77.7 miles if Louis bikes for 10 hours.

What is f(a+2)<br> A.<br> B.<br> Or<br> C.

Damm [24]

Answer:

Step-by-step explanation:

f(x) = 3(x + 5) + 4/x

To find f(a + 2) , put a + 2 in place of every x

f(a + 2) = 3 (a + 2 + 5) + 4/(a + 2)

f(a + 2) = 3 (a + 7) + 4/(a + 2)
