$a = 0.83 {ms}^{ - 2}$

Step-by-step explanation:

The walking has an initial velocity of 0m/s.

After 6 seconds he is now traveling at 5m/s.

So we use the equation:

v = u + at

where u=0 m/s is the initial velocity, v=5m/s is the final velocity, and t=6 seconds is the time.

We substitute to get:

5 = 0 + 6a

6a = 5

$a = \frac{5}{6}$

$a = 0.83 {ms}^{ - 2}$

-19/42

Step-by-step explanation:

Given the equation $\frac{5}{7}+(-\frac{7}{6} )$ , to find the equivalent expression, the following steps must be taken;

$\frac{5}{7}+(-\frac{7}{6} )\\\\= \frac{5}{7}-\frac{7}{6} \\\\find\ the\ LCM\\\\=\frac{6(5)-7(7)}{42}\\$

$= \frac{30-49}{42}\\ \\= \frac{-19}{42}$

-19/42 gives the required answer
