Answer:
9/2
Step-by-step explanation:
in order to find the fraction form of 4.5... we need to set a denominator. The denominator has to be greater than 1 because we 4.5 is not a whole number...
we want the simplest denominator in the end... so we'll pick 2 for a denominator and change it if it doesn't work in the end...
now that we know the denominator... we have to make the numerator 4 times larger than the denominator (2)... when we do this... we get 8/2
since we made the numerator 4 times larger than the denominator... we know that 8/2 is the same as 4
now we need to find the remaining 1/2
this can be done by simply adding 1/2 to 8/2 (which is easily done thanks to a common denominator)
Since 9/2 cannot be simplified any further... it is our final answer

I beilieve its B? Ive never heard about dances for inuguration.
2+2+1 3/4+1 1/4+1+1=9 . Hope this helps :)
Y = 2x - 2
x + 3y = 15
I'll do substitution by solving for y:
y = 2x - 2
Solve for y for the second equation:
y = 5 - x/3
Substitute:
2x - 2 = 5 - x/3
Add x/3 to both sides:
7x/3 - 2 = 5
Add 2:
7x/3 = 7
Multiply by 3:
7x = 21
Divide by 7:
x = 3
Substitute x in for one of the original equations:
y = 2(3) - 2
y = 6 - 2
y = 4
The solution set is (3, 4).
