Firdavs [7]
The average speed of the truck is calculated by dividing the total distance traveled in a span of the total time given. From the given above, the total distance traveled is
                       total distance = 203 mi + 243 mi = 446 mi
and the total time it took for the whole trip is
                       total time = 3.5 h + 4.5 h = 8 h
The average speed is therefore,
                       average speed = 446 mi/8 h = 55.75 mi/h
Thus, the answer is letter A.

Value of x is 3.2x-9.6=38.4?
Svetradugi [14.3K]

Answer:

The steps that can be done to both sides of the equation is: Add 9.6, then divide by 3.2

Step-by-step explanation:

Solve the equation:

3.2x - 9.6 = 38.4

-First you add both sides 9.6:

3.2x -9.6 +9.6 = 38.4 +9.6

3.2x = 48

-Then, you divide both sides by 3.2:

\frac{3.2x}{3.2} = \frac{48}{3.2}

x=15
