Answer:
Option D is correct.
Value of x is in the solution set of given equation is., 4
Step-by-step explanation:
Given that: .....[1]
Find the value of x is in the solution set;
Add 5x to both sides of equation [1];
Simplify:
Add 3 to both sides we get;
Divide both sides by 7 we get;
x > 2.
Then, we have the solution set for x is:
Therefore, the value of x is in the solution set is, 4

2.1 m
Step-by-step explanation:
The gutter is in the shape of a cylinder.
Its volume is 20 liters and its diameter is 11 cm (0.11 m).
Its radius is half of its diameter => r = 0.055 m.
The volume in cubic metres:
1 litre = 0.001 cubic metres
20 litres = 20 * 0.001 = 0.02 cubic metres
The volume of a section of guttering is given as:
where h = length of the guttering
Therefore:
The length of the section of guttering is 2.1 m long.
