I think it’s 24 I could be wrong but I’m pretty sure
First find the law
8.6-1.4n
so, 64th is 8.6-1.4x64
I think is -81
No but it is true that the two equations are parallel.
In order to subtract fractions, we must find a common denominator, then subtract the numerators.
The common denominator (LCM(3, 5)) is 15.
We must multiply the first numerator by 5, because 3*5=15 and the second numerator by 3 because 5*3=15.
We get
.
All we need to do now is subtract the numerators:
.
The answer is 14/15.
