This for some reason is in the middle school I'll move that for you and y = 17 I think
Answer:
x< -
Step-by-step explanation:
x 8x_16>8x+64
Add similar elemants:x - 8x= -7x
-7x - 16 > 8x + 64
Add 16 to both sides
-7x- 16 + 16 > 8x + 64 + 16
Simplify
- 7x > 8x + 80
Subtract 8x from both sides
-7x - 8x > 8x + 80 - 8x
Simplify
-15x > 80
Multiply both sides by - 1 ( reverse the inequality)
(-15x) ( - 1) < 80 ( - 1 )
simplify
Answer:
x = 135°
Step-by-step explanation:
6 sided polygon = hexagon
The sum of the interior angles of a hexagon = 720°
⇒ 4x + 90 + 90 = 720
⇒ 4x = 720 - 90 - 90
⇒ 4x = 540
⇒ x = 540 ÷ 4
⇒ x = 135°

The Median is the middle value of whatever data set, which means the median is 3 since its the middle value
Answer:
R = 20
Step-by-step explanation:
mean age = sum of ages/no. of men
sum of ages of the men that left = 55 + 63 = 188
remaining sum = 50R - 118
remaining no. of men = R - 2
now mean age = 50 - 1 = 49 years
49 = 50R-118/R-2
49(R - 2) = 50R - 118
49R - 50R = -188 - 98
-R = -20
R = 20
