We are required to write an inequality for the expression and also solve it
The number y is at least 10.9
let
the unknown number = y
The sum of a number y and 6.2 = y + 6.2
y + 6.2 ≤ -4.7
y ≤ -4.7 - 6.2
y ≤ 10.9
Therefore,
The expression is represented by the inequality y + 6.2 ≤ -4.7 and y ≤ 10.9

Answer:
12,500 units
Step-by-step explanation:
Given:
Selling cost of the pump = $10
Variable cost of producing each unit = 60% of selling cost
or
Variable cost of producing each unit = 0.60 × $10 = $6
Monthly fixed cost = $50,000
Now,
The profit per unit = Selling cost - Variable cost
or
The profit per unit = $10 - $6 = $4
Therefore,
The breakeven point = 
or
the breakeven point = 
or
the breakeven point = 12,500 units
Answer:
Explained below.
Step-by-step explanation:
The formula for the interior angle of any regular polygon is given as;
Interior Angle = 180(n - 2)/n
Where n is number of sides
We are told the interior angle is 40°
Thus;
180(n - 2)/n = 40
Cross multiply to get;
180n - 360 = 40n
180n - 40n = 360
140n = 360
n = 360/140
n = 2.57
Number of sides of a regular polygon cannot be in decimal nor can it have less than 3 sides.
Thus, a shape with interior angle of 40 cannot be a polygon.
Answer:
Plug x-7 in for y, in the bottom equation.
x - 7 = 2 + 2x - 4
x - 7 = 2x - 2
x = 2x + 5
-x = 5
x = -5

Determine the percentage of the shaded cubes
First, we calculate the number of boxes:
Express as multiplication
This implies that there are 20 cubes in the box.
The percentage of the shaded cubes is:
<em>30% were shaded</em>
