Answer:
x = 93
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
x - 73 + x + 67 = 180
2x - 6 = 180 ( add 6 to both sides )
2x = 186 ( divide both sides by 2 )
x = 93
Answer:
t=1.06x+10 where x=The amount of tickets bought
Step-by-step explanation:
you multiply x by 1.06 to add the extra tax onto it.
You add the 10 to add the $10 booking fee
Answer:
(a) 
(b) 
Step-by-step explanation:
GIVEN: Auditoriums are often designed so that are fewer seats per row for rows closer to the stage. Suppose you are sitting in row 
in an auditorium and notice that there are 
seats in your row. It appears the row in front of you has 
seats and the row behind you has 
seats. Suppose this pattern continues throughout the auditorium.
TO FIND: a) How many seats are in the first row b) How many seats are in the 
row?
SOLUTION:
total seats in 
total seats in 
total seats in 
as it clearly form an A.P. with 
(a)
let total seat in first row be 
as total seats in 
total seats in first row are
(b)
total seats in be 
total seats in row are
Answer:
69.1
Step-by-step explanation:
<em>Mean height of 14 students = 69.0 inches</em>
<em>Mean = sum of data/number of data</em>
<em>69 = sum of data/14</em>
<em>sum of data = 966</em>
<u>FOR NEW MEAN:</u>
<em>Height of additional student = 70.5</em>
Mean = sum of data/ number of data
Mean = 966+70.5/14+1
Mean = 1036.5/15
Mean = 69.1
Therefore, the mean height of the 15 students in the class is 69.1
Answer:
c = (y-0.13y)(1.08)
Step-by-step explanation:
c = cost and y = the original price
The amount of money off is 13% of y, or 0.13 of y. You would subtract that from y to get the price of the cards with the discount. For final cost, you need the cost of the cards (1) plus the cost of tax (8%, or 0.08). 1+0.08 is 1.08, so that's what you would multiply y by to get the final cost of the cards.
Hope this helped!
