Answer:

c < 2

Step-by-step explanation:

- (7c - 18) - 2c > 0 \\  - 7c + 18 - 2c > 0 \\  - 7c - 2c + 18 > 0 \\  - 9c + 18 > 0 \\  - 9c > 0  - 18 \\  - 9c >  - 18 \\ c <  \frac{ - 18}{ - 9}  \\ c < 2

Answer:

c < 2

Step-by-step explanation:

- (7c - 18) - 2c > 0 ← distribute parenthesis by - 1 and simplify

- 7c + 18 - 2c > 0

- 9c + 18 > 0 ( subtract 18 from both sides )

- 9c > - 18

Divide both sides by - 9 , reversing the symbol as a result of dividing by a negative quantity.

c < 2

Find the length of the line segment formed by the points (2, 3) and (2, 5)
SCORPION-xisa [38]

Answer:

2 units

Step-by-step explanation:

Given data

The points are  (2, 3) and (2, 5)

x1= 2

y1= 3

x2= 2

y2= 5

substitute into the distance between two points formula

d=√((x_2-x_1)²+(y_2-y_1)²)

d=√((2-2)²+(5-3)²)

d=√(2)²)

d=√4

d= 2 units

Hence the length is 2 units

Elena-2011 [213]
The median is the middle score, it is also the average of the two middle scores when total number is even.

original 3 scores:  89, 90, 95  ----> median = 90

with final score:  89,90,X,95  ----> median = 91.5

(90+x)/2 = 91.5
90+x = 183
x = 93

Final score was a 93.
