Ineed an equality for both of these : ) so

Inequalities will be

Step-by-step explanation:

Since we have given that

In First Case :

Number of scores Jenny scored in one part exam = 47

Let the number of scores Jenny scored in second part exam be "P"

And she wants to score in combined exam = atleast 85

So, the system of inequality will be

So, the range of P must be

Similarly,

In the second case,

Least amount Tom wants to save for a trip = $2000

Amount he saved so far = $375

Let the amount he needs to save for going for a trip be "M".

So, System of inequality will be

So, Value of M will be

answer: the answer to your question is parallel

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
