Answer:

x = -4

Step-by-step explanation:

Distribute the -2 into the parentheses and your equation becomes -8x - 8 - 3x - 2 = 34

Then combine the -8x and -3x as well as the -8 and -2 to have -11x - 10 = 34

Add 10 to both sides and get -11x = 44

Divide both sides by -11 for x=-4

If i start my trip driving at x mph for a hours and then go 5 mph slower for the next 2 hours what is the total distance i trave

Darya [45]

Total distance travelled = (x.a + 2x -10) miles .

How to solve such time related questions?

The key concept for solving such questions is the relationship between speed, distance and time.

The relationship between them is Distance = Speed X Time

The whole trip can be divided into two parts

Part 1 :- Speed = x mph and time = a hours

∴ Distance = x .a miles

Part 2 :- Speed = x -5mph and time = 2 hours

∴ Distance =(x-5).2 = (2x -10)miles

Total distance = (x.a + 2x -10) miles
