Answer:
13 2/9
Step-by-step explanation:
Cows eats=5 3/5 Hays everyday
Horses eats=1 5/6 as much as the cow
=1 5/6 of what the cow eat+5 3/5
=1 5/6 × 5 3/5 + 5 3/5
=11/6×28/6+28/6
= 308/36+28/6
=308+168/36
=476/36
=13 8/36
=13 2/9
2 tens 15 ones is equal to 35
1/2(6-y)=4
Distribute. 3-1/2y=4
Subtract. -1/2y=1
Divide. Y=-2

<em>For another information, when D > 0, there are 2 real roots.</em>
<em>When D = 0, there is only one real root.</em>
<em>And when D < 0, there are no real roots (also known as imaginary.)</em>
