Tuesday=x
Wednesday=2x
Thursday=<u />\frac{1}{2} x

x+2x+ \frac{1}{2} x=9 \\ \frac{7}{2}x=9 \\ \frac{7}{2}x*2=9 *2\\ 7x=18\\ \frac{7}{7} x=\frac{18}{7}\\ x=\frac{18}{7}

Remember that the x value is only for Tuesday's distance; therefore:

Tuesday= \frac{18}{7}miles
Wednesday= \frac{36}{7}miles
Thursday= \frac{9}{7}miles

The equation would be x+2x+1/2x=9 miles. Add all the like terms. x+2x=3x. 3x+1/2x= 3 1/2x. So 3 1/2x=9.
Then you would have to do 3 1/2x divided by 3 1/2 which would equal x. Then, 9 divided by 3 1/2 which would equal about 2.57....not completely sure but try it...

x=0.24273858921 so x = 24.27385...%

2k^2-5k-18=0 what is both of the values of k? plz help!!! 15 pts!!!
ddd [48]
To factor quadratic equations of the form ax^2+bx+c=y, you must find two values, j and k, which satisfy two conditions.

jk=ac and j+k=b

The you replace the single linear term bx with jx and kx. Finally then you factor the first pair of terms and the second pair of terms. In this problem...

2k^2-5k-18=0

2k^2+4k-9k-18=0

2k(k+2)-9(k+2)=0

(2k-9)(k+2)=0

so k=-2 and 9/2

k=(-2, 4.5)
