First compute the discriminant delta:
9^2-4*1*20=1. 
Using the quadratic formula, we get the solutions:
\frac{-9-1}{2} =-5\\ \frac{-9+1}{2}=-4

Olivia is planning to study for 8 hours. she has to spend studying English twice the time she needs for science and the time she
vaieri [72.5K]

Answer:

science = \frac{4}{3} \ hours

English = \frac{8}{3} \ hours

Math = 4 hours

Step-by-step explanation:

let the number of hours spend on science = x

Hence the number of hours on English will be = 2x

Given that the number of hours spend on science is one third of the time spend on maths. Hence the time spend on math is 3 times that of the time spend on science. That the time spend on maths is = 3x

Hence the total time to study is

x+2x+3x

which is given as 8 hours

Hence

x+2x+3x =8

6x=8

dividing both sides by 6

\frac{6x}{6}=\frac{8}{6}

x=\frac{8}{6}

x=\frac{4}{3}

Hence the number of hours foe studying science = \frac{4}{3}

Number of hours to study English = \frac{4}{3} \times 2=\frac{8}{3}

Number of hours to study Math= \frac{4}{3} \times 3=4
