18 because that’s the greatest common factor for all of them
7 1/2 is to the left of 17 2/3 on a number line because 7 1/2 is less then 17 2/3
Angles 7, 6, 3, 2 are all vertical angles, which mean they are congruent (equal)
so if angle 7 is 115° so are 6, 3, and 2
so the measure of angle 2 is 115°
An inequality is solved by more than one value - usually an interval, or a union of intervals.
In this case, we have:
Add 14 to both sides:
Divide both sides by 12:
Total tickets sold = 159
Total sales = $1100.60
Child admission = $5.20
Adult admission = $8.90
Assumed all 159 tickets are Child admission tickets
Total sales = 159 x 5.2 = $826.80
Difference in amount = $1100.60 - $826.80 = $273.80
The difference must be contributed by the Adult Admission Tickets, which has a difference of $8.90 - $5.20 = $3.70
$273.80 ÷ $3.70 = 74 adult tickets
159 - 74 = 85 child tickets
