We have x + y = 140 degrees and x = 5y - 13 ;
Then, 5y - 13 + y = 140;
6y - 13 = 140;
6y = 153;
y = 153 ÷ 6;
y = 25.5 degrees;
x = 140 - 25.5;
x = 114.5 degrees;
Answer:
r^6
Step-by-step explanation:
In the laws of indices, it states that for division of indices of the same bases, there is a subtraction of indexes or powers.
For example, a^x/a^y = a^(x-y)
Therefore, r^9/r^3 = r^(9-3) = r^6
