Answer:
$39 did Gavyn get
Step-by-step explanation:
Given the statement: Sarah and Gavyn win some money and share it in the ratio 5:3.
Let the number be x
Then, Sarah win money be 5x and Gavyn win money be 3x.
Also, it is given that Sarah gets $26 more than Gavyn.
⇒ 5x = 26 + 3x
Subtract 3x from both sides we get;
5x -3x = 26 + 3x -3x
Simplify:
2x = 26
Divide both sides by 2 we get;
Simplify:
x =13
∵Gavyn win money 3x = 3(13) = $39
Therefore, Gavyn get, $39.
Correct option is C)
On putting x=2y+5 in second equation, we get
y=(4y+7)(2y+14)
⇒8y 2 +70y+98=y
⇒8y 2+69y+98=0
Discriminant D=69 2−4(8)(98)=1625>0
Hence, the equation has 2 real roots.
Therefore, there are 2 ordered pair.
Option C is correct.
