Answer:
9 hours
Step-by-step explanation:
Using the initial ratio of 15 tickets in half an hour, you can set up a proportion (equivalent ratios) to find the amount of time it would take to sell 270 tickets:
Where 'x' is the amount of time to seel 270 tickets.
Cross-multiply: 0.5(270) = 15x or 135 = 15x
Divide: 15x/15 = 135/15 or x = 9 hours
5.6*1 2/5 = 5 3/5 * 1 2/5 =28/5 * 7/5 = 196/25 = 784/100 = 7.84 or 7 21/25
if, 1 + 3 - (8 * 334 * 123) = x
then, x = -328652
x = 1048576
250+500=750 , 268+524=792 so therefore 250+500 is the answer
