The focal length, F, in a camera is given by the following function, where d is the distance from the lens in the camera to the object being photographed. Write an equation that expresses distance, d, as a function of the focal length, F.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this

he has now walked a total of what?

if i know what this is maybe i can
