2.4=-5y+14.9
We move all terms to the left:
2.4-(-5y+14.9)=0
We get rid of parentheses
5y-14.9+2.4=0
We add all the numbers together, and all the variables
5y-12.5=0
We move all terms containing y to the left, all other terms to the right
5y=12.5
y=12.5/5
y=2+2.5/5
Y=2.5
There are 10 possible digits and 26 possible letters.
To find the answer to this problem we have to multiply 9 as many digits has the hotel reservation number and 26 as many letters it has.
It means:

There are 1,119,214,746 possible reservation numbers.
Answer:
75%
step-by-step explanation:
so if 7 were girls we would subtract to find the number of boys
28 - 7
21 boys
100% = 28
x% = 21
100%/x% = 28\21
x = 75
H is 2.5 because 2.5 x 2 is 5 and then you do 5 + 15 and you get 20
