<u><em>Explanation:-</em></u>
Given that a× 70 = b
Dividing 'a' into both sides, we get
⇒
we have to find the value
= 3× 70
= 210
Answer:11-4x5 = 11-20 = -9 or you could treat the "difference" as always positive, the absolute value of -9, or 9

Step-by-step explanation:
Representing inequalities on number line:
First of all we write the inequalities that are to be represented.
Let x represent the elevation of the miner at any time of the day.
The minimum elevation is 6 ft below the sea level. If we consider the sea level as 0 on the number line, the lower limit is -6.
The maximum elevation is 6 ft above the sea level. Hence the upper limit is 6.
The elevation throughout the day is represented by the inequality:
-6 ≤ x ≤ 6 and represented on the line as shown in the picture attached.
Note: The solid end points of the line at 6 and -6 means that 6 and -6 are included in the inequalities.
V = ¹/₃Bh
V = ¹/₃(27)(15)
V = ¹/₃(405)
V = 135m³
