Answer:
x=2
TU:4(2)-1=7
UB: 3
TB: 10
Step-by-step explanation:
4x-1+2x-1=5x
6x-2=5x
6x=5x+2
subtract 5x from both sides
x=2
TU: (4x-1)
4(2)-1
8-1
7
TU:4(2)-1=7
UB: (2x-1)
2(2)-1
4-1
3
UB: 3
TB: 5(2)
TB: 10
Answer:25
Step-by-step explanation:
I would say D. It makes the most Since
Answer:

Step-by-step explanation:
Let A and B events. We have defined the probabilities for some events:

Where A' represent the complement for the event A
The complement rule is a theorem that provides a connection between the probability of an event and the probability of the complement of the event. Lat A the event of interest and A' the complement. The rule is defined by:
So for this case we can solve for P(A) like this:

And now we can find
using the total probability rul given by:

And if we replace the values given we got:

And that would be the final answer.
