Answer:

see below

Step-by-step explanation:

5) 4n + 6 - 2n = (2n + 3)

2n + 6 = 2n + 3
0 = -3

<h3> No solution</h3>

6) 6m - 8 = 2 + 9m - 1

6m - 9m = 2 - 1 + 8
-3m = 9
m = 9/-3

7) -v + 5 + 6v = 1 + 5v + 3

-v + 6v - 5v = 1 + 3 - 5
0 = -1

<h3> No solution</h3><h3 />

8) 2(3b - 4) = 8b - 11

6b - 8 = 8b - 11
6b - 8b = 8 - 11
-2b = -3

Which is a good comparison of the estimated sum and the actual sum of 7 9/12 + 2 11/12?

natta225 [31]

7 9/12 = 7.75
2 11/12 = 2.917

So we can round both of these up.

7.75 rounds to 8
2.917 rounds to 3

8 + 3 = 11

So the estimated sum is 11.

7 9/12 + 2 11/12 = 10 2/3

So the actual sum is 10 2/3.

The estimated sum is a pretty good estimate to the original number.

if I set off for the market,a distance of 11km at 10am. And walk at an average speed of 3km per hour,At what time will I reach t

earnstyle [38]

Answer:

At 1:40 pm you will reach the market.

Step-by-step explanation:

Distance (d) = 11 km

Average speed (v) = 3 km/h

Formula:

$\rm Average \: speed = \dfrac{Distance}{Time} \\ \\ \rm 3 = \dfrac{11}{t} \\ \\ \rm t = \dfrac{11}{3} \\ \\ \rm t = 3 \frac{2}{3} \\ \\ \rm t = 3 hr \: 40min$

It will take 3 hours 40 minutes to reach the market.

So, if you set off for the market at 10 am you will reach market by 1:40 pm (10 am + 3hr 40min).
