Answer: for 3) 427 hikers
Step-by-step explanation: b + 178 + b = 676

Answer:
It would be 70
Step-by-step explanation:
First step: Divide 156 by 2
156 / 2 = 78
Second Step: The half of 156 is 78. Now we have 78 laptops and desktops, and as we know the question says that "there are 8 more laptops than desktops", the next step to follow is to subtract 8 from 78 (Desktops) and add 8 to the 78 (Laptops).
78 - 8 = 70 Desktops
78 + 8 = 86 Laptops
Hope this helps :)
