Sam has already biked 1/4 of all the distance and 12 miles, and he still needs to bike 3/8 of the total distance and 9 miles. What's the total distance

let the total distance be x. So the equation goes as follows:-

(1/4)x+(3/8)x+9+12=x

On solving

(2x+3x+168)/8=x

5x+168=8x

168=3x

x=168/3

x=56km

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
