A. x=50. If you are charged $2 when you go over 200 miles and he drove 250 then he drove 50 miles over so the answer is 50.
Every time you see r, replace it with -3. Every time you see s, replace it with 5. You are working wth exponents, which means that the little number next to the big number (exponent) is how many times you multiply the big number by itself.
For example, 5^3=5x5x5=125 (isn't one of the problems you are trying to solve)
If the expodent is negative, then you divide. S<span>so if it's like 5^-3, you do 1 ÷ 5 ÷ 5 ÷ 5 = 0.008 </span>
Hope this helps! :)
Answer: The reference angle for 300° is 60° and the reference angle for
is 
Step-by-step explanation:
1. So you find the reference angle by subtracting 300 from 360. Therefore, the measure of the reference angle is 60 degrees.
