Answer:23
Step-by-step explanation:
7x^2 - 16x - 8 = 0
using the quadratic formula x = [ -(-16)+/- sqrt((-16^2 - 4*7-8] / 2*7
= (16 +/1 sqrt 480) / 14
= 2.71, -0.42 to nearest hundredth
Since the ratio of mother to daughter is 4:1, the weight of the mother and daughter together is five times the weight of the daughter.
In fact, if the daughter weights 
pound, the mother weights 
pounds, and the total weight is 
.
We know that this total is 185 pounds, so we have
So, the daughter weights 37 pounds.
