Answer:
(a)x + y = 58 and x = y + 14
(b) You sold 36 and your friend sold 22.
Tickets that you sold = x
Tickets that your friend sold = y
Together, the two of you sold 58 tickets.
x + y = 58
You sold 14 more than your friend
x = y + 14
So the two equations are:
x + y = 58
x = y + 14
------------------------------------------------------------------------
Construct system of equations and solve for x and y
------------------------------------------------------------------------
x + y = 58 ------------ (1)
x = y + 14 -------------(2)
Substitute equation (2) into equation (1)
(y + 14) + y = 58
y + 14 + y = 58
2y + 14 = 58
2y = 58 - 14
2y = 44
y = 22 ---------------- Substitute into equation (2)
x = y + 14
x = 22 + 14
x = 36
------------------------------------------------------------------------
Find the tickets you and your friend sold
------------------------------------------------------------------------
you = x = 36
your friend = y = 22
------------------------------------------------------------------------
Answer: (a) x + y = 58 and x = y + 14
(b) You sold 36 and your friend sold 22.

Answer:
121
Step-by-step explanation:
Number of sides = n = 7
Sum of all the interior angles = (n -2)*180 = (7-2) *180
= 5 *180
= 900
x + 125 + 119 +117 +145 + 133 + 140 = 900
x + 779 = 900
x = 900 - 779
x = 121
