Answer:
Step-by-step explanation:
We can write the following system of equations:
Adding both equations together, we isolate 
and get:
Plugging 
in any of the equations, we can solve for 
:
Verify that the solution pair 
works 
Therefore, the two numbers are 
.

Answer:
Step-by-step explanation:
∩ 
is asking for the intersection of sets 
and , or simply, which numbers can be found in both sets.
The numbers shared between the two sets are 
.
Next, we need to union this result with the set 
, or simply, combine the numbers in both sets together.
This would result in 
Answer:$3334.5
Step-by-step explanation:
A=p(1+r/100)^n
A=1400(1+7.5/100)^12
A=1400(1.075)^12
A=1400×2.381
A=$3334.5
