First convert the feet to inches:
3 feet= 36 in.; 4 feet=48 in.
Make an equation for each one:
Type A: h=36+15x
Type B: h=48+10x
Since the questions wants the heights to be equal, h=h so you can substitute so you have:
36+15x=48+10x
5x=12
x=2 2/5 years or 2.4 years
Observe that 85 is an odd number. That means, one of the prime numbers must be even to have an odd sum with another odd number. As we know, the only even prime number is 2. Hence, the other number is 83.
So, the product of these two prime numbers is 83 x 2 = 166.
Thus, the answer is 166<span>. </span>

Answer:
72
Step-by-step explanation:
you take 85 * 9
85 = # of seats
9 = # of buses
then you get 765
next, you take 765 - 693
765 = # of seats
693 = # people who bought tickets for a trip
finally you get 72
72 = # of empty seats
