Answer:
B
Step-by-step explanation:
Because I got it right
To solve this problem, divide both sides by 5 and you get a ratio of 24 to 1. The answer is 24 minutes per night. I hope this helped!
Set the first number as x.
Note that three consecutive integers are 3 numbers that are 1 greater than the previous.
(x) + (x + 1) + (x + 2) = 72
Simplify. Combine like terms
3x + 3 = 72
Isolate the x. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 3 from both sides
3x + 3 (-3) = 72 (-3)
3x = 69
Next, divide 3 from both sides
3x/3 = 69/3
x = 23
------------------------------------------------------------------------------------------------------------------------
23 is your first answer
Plug in 23 for each x.
------------------------------------------------------------------------------------------------------------------------
(x) + (x + 1) + (x + 2) = 72
(x) = 23
(x + 1) = 23 + 1 = 24
(x + 2) = 23 + 2 = 25
23, 24, 25 are your answers
