Answer:
She added 83 instead of subtracting
Step-by-step explanation:
83 + n = 110
We want to do the opposite to n
We are adding 83 to n. The opposite is subtract 83
83+n-83 = 110-83
n =27
Mia
83 + n = 110
83 + 83 + n = 110 + 83
163+n=193
X = number of students who are members.
<span>19-x is the number of people who are not members.</span> x number of people paid $11 for tickets and (19-x) number of people paid $13.$11x+$13(19-x)=$209 for the total cost of the tickets.
$11x+ $247-$13x=$209 $11x-13x = $209 - $247
$-2x = $-38
divide -2 by both sides
x=19, meaning that all of the students are members.

Step-by-step explanation:


Answer:
1.5 times per second
(1 time per second if rounded to a whole number)
Step-by-step explanation:
1 minuet is equal to 60 seconds
Because you are given 88 vibrations in one minute, you will divide 88 by 60 seconds. You want your answer in seconds.
88/60 gives us 1.466666667 on a calculator
So the guitar gives a vibration of 1.466666667 per second
If we round this, we get 1.5 vibrations per second
Or, if we round 1.4666 to a whole number then it is 1 vibration per second
