Answer:
x = 17
∠A = 114°
Step-by-step explanation:
In the figure attached, the complete question is shown.
From the figure, we know that:
∠A = ∠B
Replacing with the expressions, we get:
6x+12 = 3x+63
6x - 3x = 63 - 12
3x = 51
x = 51/3
x = 17
∠A = 6(17)+12
∠A = 114°
Hello There!
<u><em>The number of adult tickets sold in the school play = 225</em></u>
<u><em></em></u>
<u><em>Total Number Of Tickets = 505</em></u>
<u><em>Number Of Student Tickets = x + 55</em></u>
<u><em></em></u>
Number of adult tickets sold can be represented by X
Number of student tickets = X + 55
X+X+55=505
2x+55=505
2x=505-55
2x=450
X=225
9. ¹/₃(x + 6) = 8
¹/₃(x) + ¹/₃(6) = 8
¹/₃x + 2 = 8
<u> - 2 - 2</u>
3 · ¹/₃x = 6 · 3
x = 18
15. ¹/₅(x + 10) = 6
¹/₅(x) + ¹/₅(10) = 6
¹/₅x + 2 = 6
<u> - 2 - 2</u>
5 · ¹/₅x = 4 · 5
x = 20
20. ¹/₈(24x + 32) = 10
¹/₈(24x) + ¹/₈(32) = 10
3x + 4 = 10

x = 2
32. 5 - ¹/₂(x - 6) = 4
5 - ¹/₂(x) - ¹/₂(-6) = 4
5 - ¹/₂x + 3 = 4
5 + 3 - ¹/₂x = 4
8 - ¹/₂x = 4
<u>- 8 - 8</u>
-2 · (-¹/₂x) = -4 · (-2)
x = 8
33. ²/₃(3x - 6) = 3
²/₃(3x) - ²/₃(6) = 3
2x - 4 = 3

Answer:
$15.95
Step-by-step explanation:
cost of 1 gram of sweet = $2.10 / 50 = 0.042
Cost of 380 g = 380 x 0.042 = $15.96
to the nearest 5 cent = 15.95
