Answer:
-2
Step-by-step explanation:
substitute:
(10 + 6)÷4(-2)
= 16÷-8
-2
If two events are independent, then P(A and B) = P(A) x P(B).
In your situation, you need to solve 0.185 = 0.25 x P(B).
Can you take it from there?

Answer:
1 hour and 30 minutes.
Step-by-step explanation:
While carrying her fancy 360-degree camera, a crew artist Sarah Jane can walk at a rate of 2 miles per hour.
We are asked to determine the time required by Sarah to walk to a place that is 3 miles away from her.
Since Sarah can walk at a rate of 2 miles per hour.
Hence, she walks 3 miles in
hours i.e. 1 hour and 30 minutes. (Answer)
{Here we have used the unitary method assuming that Sarah walks at a constant rate}
Answer: Choice B)
2x+5(2x+3) = 3
============================================
Reasoning:
We start with the second equation 2x+5y = 3
Since y = 2x+3 from the first equation, we can replace every copy of y with (2x+3). This replacement is valid because y and 2x+3 are the same.
So that's how we go from 2x+5y = 3 to 2x+5(2x+3) = 3
This replacement is done to get rid of the y variable, and it allows us to solve for x later on.
