Answer:
Step-by-step explanation:

I believe the answer would be 28

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.

Answer:
Hi, I'm unsure as to what digit you wanted us to round the answer to, so I rounded the answer to the 4 most commonly used decimal places.
First off, we figure out that <em>614 divided by 31 equals </em><em><u>19.8064516129.</u></em>
Rounded to the nearest thousandth, that's <u><em>19.806.</em></u>
Rounded to the nearest hundredth, that's <u><em>19.81.</em></u>
Rounded to the nearest tenth, that's <u><em>19.8.</em></u>
Rounded to the nearest whole number, that's <u><em>20.</em></u>
