Need bernard typically runs x km/hour. while he was sick, he only ran 41.5 km/hour. what equation represents that the difference in his speeds is 13.5 km/hour? x – 41.5 = 13.5 41.5 + x = 13.5 13.5 – x = 41.5 13.5 – 41.5 = x

The answer is

Step-by-step explanation:

To find the correct equation we have to separate each one of the terms:

Typically runs = x km/hour

Sick run = 41.5 km/hour

Difference in speed = 13.5 km/hour

This is a case of a subtract, so we have to subtract the typically run and the sick run and the answer will be the difference in speed, this is=

In the terms of the answers, we have:

The answer is

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
