Answer:
66/100 (or simplify to 33/50), 0.89
Step-by-step explanation:
5/9-3/8+(-1/4)+1 4/9+1 5/8=3
(x-4)/(3)(x+5)(x-5)
In order for the rational expression to be undefined, the denominator must be equal to 0.
Thus, set 3(x+5)9(x-5)=0
x=5 and -5
the coefficient of x is 1
She needs to score a 91 on her next test because 85+78+77+69+91=400 and 400 divided by 5 gives you a mean of 80.
