A survey is conducted in a certain neighborhood to find out residents' favorite vacation spot. Two-fifths of the respondents, or 80 residents, said they like spending their vacation at the beach. Which equation represents the number of residents, r, surveyed? How many residents were surveyed? (1 point)
O ≥p = 80; 32 residents were surveyed.
0 2p = 80; 200 residents were surveyed.
0 5r = 80;200 residents were surveyed.
O 80r = 2; 200 residents were surveyed.
The correct equation that represents the number of residents surveyed is: 5r = 80.
To find out how many residents were surveyed, we can solve the equation for r:
5r = 80
Dividing both sides of the equation by 5:
r = 16
Therefore, 16 residents were surveyed.
The correct equation that represents the number of residents surveyed is 5r = 80. To find the number of residents surveyed, we can solve this equation for r.
5r = 80
Dividing both sides of the equation by 5 gives:
r = 80/5
r = 16
Therefore, the number of residents surveyed is 16.
To solve this problem, we need to set up an equation and then solve for the number of residents surveyed.
Let's start with the information given: Two-fifths or 2/5 of the residents surveyed said they like spending their vacation at the beach, which is equal to 80 residents.
So, we can set up the equation where "r" represents the total number of residents surveyed:
(2/5)r = 80
To find the total number of residents surveyed, we need to isolate "r" by multiplying both sides of the equation by the reciprocal of (2/5), which is 5/2:
(2/5)r * (5/2) = 80 * (5/2)
Simplifying this equation gives us:
r = (80 * 5) / 2
r = 400 / 2
r = 200
Therefore, the correct equation that represents the number of residents surveyed is 5r = 80, and the total number of residents surveyed is 200. So, the correct answer is :
0 5r = 80;200 residents were surveyed.
