1 answer:

6 0

First you turn the mixed fraction into an improper fraction and work out 2-13 :
1/4y + 3/2 + - 11/4y-12
Then factorise :
1/4y + 3/2 - 11/4(y-3)
Then factor out y :
Y(y-3)+6(y-3)-11 / 4(y-3)
Then expand :
Y^2-3y+6y-18-11 / 4y-12
Simplify for your final answer :
y^2+3y-29 / 4y-12

The sign shows distances from a rest stop to the exits for different towns along a straight section of highway. The state depart

torisob [31]

Refer to the diagram shown below.

The exit for Freestone is built midway between Roseville and Edgewood,
therefore the distance from O to the new exit is
(1/2)*(33+55) = 44 mi.

Let x = distance from Midtown to the new exit.
Because the distance from O to the new exit is equal to (x + 17), therefore
x + 17 = 44
x = 44 - 17 = 27 mi.

Answer:
When the new exit is built, the distance from the exit for Midtown to the exit for Freestone will be 27 miles.
