Answer:
Step-by-step explanation:
We are told that n = 3m + 6. Substitutte 3m + 6 for n in the second equation, obtaining:
(3m + 6) - 2m = 2, or 3m + 6 - 2m = 2.
Combining like terms yields
m = -4.
Knowing that m = -4 allows us to calculate n. Use the first equation, n = 3m + 6, for this purpose: n = 3(2) + 6 = 12.
Thus, the solution is (2, 12).

Answer:
B
Step-by-step explanation:
Wrapping paper is covering the box, aka the area, therefore it is the surface area.
Correct question is;
Speed of a boat in standing water is 9 kmph and the speed of the stream is 1.5 kmph. A man rows to a place at a distance of 105 km and comes back to the starting point. The total time taken by him is:
Answer:
Total time = 24 hours
Step-by-step explanation:
We are given;
Speed of a boat in standing water = 9 kmph
Speed of the stream = 1.5 kmph
Distance rowed by the man; d = 105 km
He now came back to his starting point.
Thus, we can say that;
Speed upstream; V_up = 9 - 1.5 = 7.5 kmph
Speed downstream; V_down = 9 + 1.5 = 10.5 kmph
Now, we know that;
time = distance/speed
Thus;
Total time = time taken upstream + time taken downstrem
Total time = (105/7.5) + (105/10.5)
Total time = 14 + 10
Total time = 24 hours
