That is not a "proper" question - what else is provided here?NSH said:help with solving this problem

There are any number of "conclusions" one could draw from the above. Without parameters, there is, unfortunately, no possible way of knowing which one particular conclusion is expected for this exercise. Sorry!NSH said:If a>b, and if c>d, then....

Please consult with your instructor regarding the missing information. Thank you!

If 10>9, and if 6>5, then....you might conclude that 10>5, but...

If 10>9, and if 15>14, then....can you say that 10>14?

If 10>9, and if 6>5, then.... could say that 10+6 > 9+5 or 10-6 > 9-5 or 10*6 > 9*5 or 10/6 > 9/5 ??? One or more of these is not true. One or more are true.

I imagine you are to draw conclusions similar to these, only using a, b, c and d. In other words...

If a>b, and if c>d, then....is a+c always greater than b+d? What if a, b, c, and d are negative numbers?

\(\displaystyle \text{If }a>b\text{ and }c>d\text{, then } \hdots\)

\(\displaystyle \text{If we are concerned with the four arithmetic operations,}\)

. . \(\displaystyle \text{only }addition\text{ is "dependable."}\)

\(\displaystyle \text{We can safely conclude that: }\;\boxed{\:a + c \:> \:b + d\:}\)

\(\displaystyle \text{The others: }\begin{Bmatrix} a-c & >& b-d \\ ac & > &bd \\ \frac{a}{c} & > & \frac{b}{d}\end{Bmatrix}\;\;\text{may or may not be true.}\)

Then answer is "it cannot be determined".
