The measure of the supplement angle is 63°
Step-by-step explanation:
If two angles are supplementary then the sum of their measures is 180°
The given is:
We need to find the measure of the supplement
∵ The two angles are supplementary
∴ The sum of their measure is 180°
Assume that the measure of the supplement angle is x°
∵ An angle is 9 less than twice its supplement
- twice means times 2 and 9 less means subtract 9
∵ The measure of the supplement is x°
∴ The measure of the angle = (2x - 9)°
∵ The sume of the measures of the two angles = 180°
∴ (2x - 9)° + x° = 180°
- Add like terms
∴ (2x + x) - 9 = 180
∴ 3x - 9 = 180
- Add 9 to both sides
∴ 3x = 189
- Divide both sides by 3
∴ x = 63°

Answer: IQR = 16
Given the following data:
Cost of concert :
CITY : Q, R, S, T, U, V, W, X, Y, Z
Price : 35,36,42,38, 24,29,25, 44,49, 26
Interquartile range (IQR) = Q3 - Q1
Where,
Q3 = the upper quartile
Q1 = lower quartile
Rearranging the data:
24,25,26,29,35,36,38,42,44,49
Q3 = 42
Q1 = 26
IQR = (42 - 26) = 16
Answer:
18+2x>_0
18/2 + 2x/2
x= 9
first take the 2x to the other side which will automatically change from - to + and then divide both 18 and 2x by 2
