Answer:
x = 11.4
Step-by-step explanation:
The sum of the angles of any triangle must add up to 180°. Since we have the expressions for each angle: 5x, 8x, and (2x +9), we can solve for the variable of 'x' by adding the expressions together and setting them equal to 180:
5x + 8x + (2x +9) = 180
Combine like terms: 15x + 9 = 180
Use inverse operations: 15x + 9 - 9 = 180 - 9
15x = 171 or x = 11.4
Check: 5(11.4) + 8(11.4) + 2(11.4) + 9 = 57 + 91.2 + 22.8 + 9 = 180
Answer:
Question 1: g = 6
Question 2: v = 84
Question 3: y = 60
Question 4: w = 496
Question 5: Kyle had $400 to begin with.
Step-by-step explanation:
Question 1 explanation: 12g = 72 ⇒ g = = 6
Question 2 explanation: = 21 ⇒ v = 21 * 4 = 84
Question 3 explanation: y = 10 ⇒ 6 * y = 10 * 6 ⇒ y = 60
Question 4 explanation: w + 376 = 872 ⇒ w = 872 - 376 = 496
Question 5 explanation: K - 85 = 315 ⇒ K = 315 + 85 = 400, so Kyle had $400 originally in his account.

Step-by-step explanation:
From Thursday to Friday the points on the graph change by -5
Only 27.5% of the people asked would pay the $100 [(11/40)*100]. You need 38 out of 40 people to say they would pay $100 for a 95% confidence. I got 38 from trial and error. Hope this helps.
