Answer:
Distance between two cities that are 9 inches apart on the map is 11.97 miles (12 miles)
Step-by-step explanation:
As it is given in the question scaled distance on a map is 3 inches = 4 miles.
Now we have to calculate how many miles in 1 inches on the map = 4÷3
= 1.33miles
Now we get the value of 1 inches on the map = 1.33 miles
9 inches = 1.33 × 9 = 11.97 miles ( Probably close to 12 miles if allowing for changing elevations in the distance)
In elementary school we used to refer to this as a ratio problem; two equal ratios with one containing unknown as :
X/C = A/B
X miles / 9 inches = 4 miles / 3 inches
X = 9 (4÷3)
X = 9×1.33
X = 11.97
=12 miles

Answer:
(1/2)b^2 + 5b - 3
Step-by-step explanation:
Let the price of adult ticket and children ticket be a and c respectively
8a+5c=177.50 -> 24a+15c=532.5
12a+6c=255.00 -> 24a+12c=510
24a+15c-24a-12c=532.5-510
3c=22.5
c=7.5
a=17.5
