Speed between 145.155 and 144.809

Answers

If you are just looking for any number between you can go from 144.810 to 145.154 and you can get even more number if you add a zero to both number because there are lots more between 145.1550 and 144.8090

However, if you are looking for the number that is equidistant between them - the number in the middle, simply add them together and find the average which will be the number in the middle.
So
(145.155 +144.809)÷ 2 = 144.982

A total of 227 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was two times the number of adult tickets sold . How many adult tickets were sold?

Equations:
a + s = 227 tickets

Substitute for "s" and solve for "a":
a + 2a = 227

3a = 227
a = 75 2/3
