For this case we must raise an inequality.
We have "d" dollars initially and they are spent 12. Then:
At least 51 dollars remain, then, the sign of inequality is greater or equal in favor of the expression, that is:
Resolving:
There are at least 63 dollars left in the account.
Answer:
Answer:
(C)Angle MRN and Angle NRO
Step-by-step explanation:
A diagram of the given problem is drawn and attached below.
From the diagram:
Option A: Angle PRL and Angle LRM = Angle PRM which is not 180 degrees.
Option B: Angle ORP and Angle MRN are vertically opposite angles and are therefore not linear pairs.
Option C: Angle MRN and Angle NRO are on the line ORM and therefore forms a linear pair.
<u>Therefore, the correct option is C.</u>
