Create a word problem that involves speed
lana66690 [7]

A hockey puck is sliding on frictionless ice on an infinite hockey rink.
Its speed is 36 km/hour.  How far does the puck slide in 10 seconds ? 

 (36 km/hr) x (1,000 m/km) x (1 hr/3600 sec) x (10sec) =

         (36 x 1,000 x 10 / 3,600) meters  =  <em>100 meters</em>

What is the puck's speed in miles per hour ?

        (36 km/hr) x (0.6214 mi/km)  =  <em>22.37 mi/hr</em>

4x - 2 (x-2) = -4 + 5x -13
kolezko [41]

Answer:

x = 7

Step-by-step explanation:

Given

4x - 2(x - 2) = - 4 + 5x - 13 ← distribute left side and simplify

4x - 2x + 4 = 5x - 17

2x + 4 = 5x - 17 ( subtract 5x from both sides )

- 3x + 4 = - 17 ( subtract 4 from both sides )

- 3x = - 21 ( divide both sides by - 3 )

x = 7
