-2y - 2y - 8 = -4
Move the -8 to the -4, and that makes
-2y -2y = 4
Add the -2ys together and that makes
-4y = 4
Then divide by -4, and you will get your answer of
y= -1
Answer:
<h2><u><em>
28°</em></u></h2>
Step-by-step explanation:
<u><em>the triangles are similar, so same angles</em></u>
<u><em>the sum of the interior angles of a triangles is 180°</em></u>
<u><em>take away from 180° the know angles and you will have your answer</em></u>
180 - 62 - 90 =
28°
1/16 x 1/49 = 1/784
1/28^2 = 1/784
Your answer is B

Complete question:
Cody's school is selling tickets to the annual talent show. On the first day of ticket sales the school sold 7 senior citizen tickets and 14 student tickets for a total of 196 The school took in $104 on the second day by selling 5 senior citizen tickets and 6 student tickets What is the price each of one senior citizen ticket and one student ticket?
Answer :
Señior tickets = $10
Student ticket = $9
Step-by-step explanation:
Let :
Senior ticket = x
Student ticket = y
7x + 14y = 196 - - - (1)
5x + 6y = 104 - - - (2)
Multiply (1) by 5 and (2) by 7
35x + 70y = 980 - - - (3)
35x + 42y = 728 - - - (4)
Subtract (3) and (4)
28y = 252
y = 252 / 28
y = 9
From (1)
7x + 14(9) = 196
7x + 126 = 196
7x = 70
x = 10
Hence,
Señior tickets = $10
Student ticket = $9
