Answer:

-2x +4 = 20

Step-by-step explanation:

given

- 2x + 4 = 20

by making x the subject, you need to subtract 4 from 20

thus

- 2x = 20 - 4

- 2x = 16

and also you need to divide through by -2

\frac{ - 2x}{2}  =  \frac{16}{ - 2}

x =  - 8

3n = n² - 54

n² - 3n - 54 = 0

n² - 9n + 6n - 54 = 0

n(n - 9) + 6(n - 9) = 0

(n - 9)(n + 6) = 0

n = 9 , -6

AlexFokin [52]
Given:
Cylinder: height = 16 cm ; radius = 5 cm
cone: height = 12 cm ; radius = 4 cm

Volume of cylinder = 3.14 * (5cm)² * 16cm = 1,256 cm³
Volume of cone = 3.14 * (4cm)² * 12cm/3 = 200.96 cm³

Volume of air space = 1256 cm³ - 200.96 cm³ = 1,055.04 cm³

A ferry traveled 1/6 of the distance between two ports in 3/7 hour at this rate what fraction of the distance between the two po
Masja [62]
First, we determine the speed of the ferry by dividing the distance by the time it took to cover that certain distance. 
                                 speed = (1/6) / (3/7)
                                   speed = 7/18
Then, the distance it will travel for an hour is calculated through the procedure below. 
                         distance = (7/18hour) x (1 hour)
                           distance = 7/18
Therefore, after an hour, the ferry will be able to travel 7/18 of the distance between two ports.
