I think there is some missing information. Primarily what the price of the 'Viola' is. Also, I think there might be something else missing, since the obvious answer would be the highest value $62.00
Step-by-step explanation:
-7x + 2y = 18
6x + 6y = 0
21x - 6y = - 54
6x + 6y = 0
27x = -54
x = -2
6(-2) + 6y = 0
-12 + 6y = 0
6y = 12
y = 2
(-2,2)
Answer:
Average speed
= 5 5/6 mph , or
= 5.83 mph (to 2 decimals)
Step-by-step explanation:
Average speed is total distance divided by the total time it takes to cover the given distance.
Since uphill = 5 mph, and downhill = 7 mph, we know the average speed is between 5 and 7 mph.
Let
x = distance uphill, and also distance downhill.
Total distance = 2x miles
Total time = x/5 + x/7 hours = 12x/35 hours
Average speed
= total distance/total time
= 2x / (12x/35) mph
= 70x / 12x
= 5 5/6 mph
= 5.83 mph (to 2 decimals)
