Olin [163]3 years ago
6 0

Answer:

9(n - 9)  = 9n - 81

Step-by-step explanation:

Equivalent expressions are expressions which are equal . To determine if expressions are equivalent, simplify to lowest terms through combining like terms.

-9 - 7n + 16n  =  -9 + 9n

9(n - 9)  = 9n - 81

n - 9 + 8n  = -9 + 9n

9n - 9 = -9 + 9n

in a survey, 27% of people chose salads over a meat dish. In all, 81 people chose salads. How many people were in the survey?
adelina 88 [10]
Number of people that chose salad = 81
Percentage of people that chose salad over meat dish = 27%
Let us assume the number of people on the survey = x
Then
27% * x = 81
(27/100) * x = 81
27x = 81 * 100
27x = 8100
x = 8100/27
   = 300
So a total of 300 people participated in the survey.I hope the procedure is clear enough for you to understand. Based on this method you can always solve similar types of problems without requiring any kind of help from outside.
