I WILL AWARD BRAINLIEST!! PLEASE HELP!!! The figure below shows the movement of a pedestrian from point B to point E. Using the

jeyben [28]

Answer:

Step-by-step explanation:

A) What is the speed of the pedestrian BC, CD, and DE?

Speed from B to C = distance/time = (40 - 20) / 4 = 20/4

= 5 km/h

Speed from C to D = distance/time = 0 / 2

= 0 km/h

Speed from D to E = distance/time = (20 - 0) / (10 - 6) = 20/4

= 5 km/h

B) After what time since the stop did he arrive at point E?

Since the stop at D, he arrived at E after (10 - 6) = 4 h

C) Write the formulas for function d(t) for sections BC, CD, and DE

For BC, d = 40 when t = 0 and d = 20 when t = 4

So d(t) = 40 - 5t

For CD, d = 20 when t = 4 and t = 6

So d(t) = 20

For DE, d = 20 when t = 6 and d = 0 when t = 10

So d(t) = 5 * (10 - t) or d(t) = 50 - 5t

Solve 20 - x/3 = x/2 , put the number only in the box.

Nikitich [7]

Answer:

<h2>x = 24</h2>

Step-by-step explanation:

$20 - \frac{x}{3} = \frac{x}{2}$

Multiply through by the LCM that's 6 in order to eliminate the fraction

That's

$6 \times 20 - 6 \times \frac{x}{3} = 6 \times \frac{x}{2} \\ 120 - 2x = 3x$

Using the addition property add 2x to both sides of the equation

That's

$3x + 2x = 120 + 2x - 2x \\ 5x = 120$

<u>Divide both sides by 5</u>

$\frac{5x}{5} = \frac{120}{5}$

We have the final answer as

<h3>x = 24</h3>

Hope this helps you
