The answer is 13
If R=4 the the equation would be 4+9 which equals 13.
Answer:
Seven-thirds
Step-by-step explanation:
The give equation is 
.
The leading coefficient is 9
The constant term is 7
According to the rational root theorem, the ratio of factors the constant terms to that of the coefficient of the leading term are all possible rational roots of the given polynomial.
Base on this theorem, 
or seven thirds is a potential root because the numeration is a factor of 7 and the denominator is a factor of 9.
The price difference/ the original price and times the whole equation by 100 (to get the percentage).
> ($50/$150) x 100 = 33% (rounded)
Answer:
4/15

The total number of spins completed is 6+8+7+9 = 30
The letter B came up 8 times
P(B) = number of B's over total
P(B) = 8/30 = 4/15
