Consider the given equation:
Cross multiplying in the given equation, we get
Applying distributive property which states 
, we get
Adding '4' on both the sides, we get
Subtracting '10n' from both the sides of the equation, we get
Dividing by '-8' in both the sides of the equation, we get
Therefore, the value of 'n' is -1.

Step-by-step explanation:
Answer:
40 mph.
Step-by-step explanation:
Suppose grandma's house is 30 miles away (any distance would do but 30 is convenient).
Speed = distance / time
time = distance / speed
Time to get there = 30/60 = 1/2 hour.
Time to get back = 30/30 = 1 hour
Average speed = total distance/ total time
= (30 + 30) / ( 1 + 1/2)
= 60 / 1.5
= 40 miles per hour.
You cannot take the average of the speeds directly
(60+ 30)/2 = 45 is not correct as you cannot average ratios ( speed is a ratio).
Answer: 13.6
Step-by-step explanation:
subtract the lowest number from the highest number to find the range. in this case, the data range is 25.6−12=13.6
