Answer:
option (3) is correct.

Step-by-step explanation:
Given 
We have to solve for e.
Consider the given statement,

Cross multiply, we get,

Taking square root both sides , we get,

We know square root of 9 is 3.

Thus, option (3) is correct.

Answer:
1/3
Step-by-step explanation:
(7-2)/(17-2)=5/15=1/3

"right" is wrong in this context. ;)
Example: Most of us would see immediately that 5 is a prime factor of 50.
Write 50 as 5 * 10.
10 is not prime; it can be factored into 5 and 2.
Thus, 50 written as the product of its prime factors is 5 * 5 * 2 (answer)
a.
The required equation is 23p + 19.50 = 180.50
Let p represent the number of people who can go to the amusement park.
Since the ticket costs $23 per person, the total amount paid for ticket is rate × number of person = $23 × p = 23p.
Since we pay $19.50 for parking, the total amount spent is T = 23p + 19.50
Since the total amount equals $180.50. T = 180.50
So, 23p + 19.50 = 180.50
The required equation is 23p + 19.50 = 180.50
b.
Solving 23p + 19.50 = 180.50, we have
23p = 180.50 - 19.50
23p = 161
p = 161/23
p = 7
So, the number of people who can go to the amusement park is 7.
