Answer:
N = 22.5
Step-by-step explanation:
N/6 = 15/4
Using cross products
4N = 6*15
4N = 90
Divide each side by 4
4N /4 = 90/4
N = 45/2
N = 22.5
Answer:
x = 1 2/3 hours
Step-by-step explanation:
We can use ratios to solve
150 miles 100 miles
---------------- = ---------------
2.5 hours x hours
Using cross products
150x = 2.5*100
divide each side by 150
150x/150 = 250/150
x = 1 2/3 hours
Answer:
250
Step-by-step explanation:
i did cross multiplication 40/100 = 100/x
100*100 and divide by 40
(2x + 3)(x + 4)

I can tell you how to solve this problem.
You can find the areas using both the values as the radiuses (find the are of a circle).
Subtract the smaller area from the larger area and there is your answer.
Hope this helped.
Good Luck!
