Step-by-step explanation:
Hello!
You put -2 in for x
I don't know whether it is times x or to the power of x so I will do both
5 * 3 * x
5 * 3 * -2 = -30

5 * 3^x
5 * 3^-2
5 * 1/81 = 5/9 or 0.55555
Hope this helps!
R - Right Handed
L - Left Handed
R = 9L ( the number of right handed kids is equal to having 9*number of left handed kids)
9L + L = 30 ( since total number of people in class is 30)
10L = 30
( Divide by 10 both sides )

Hope this helped!
