Answer:
70 ft
Step-by-step explanation:
You want the actual width of a gym that is represented as 7 inches on a drawing with a scale of 1 in : 10 ft.
<h3>Scale factor</h3>
Each inch represents 10 feet, so 7 inches will represent ...
7 × 10 ft = 70 ft
The gym is 70 ft wide.
__
<em>Additional comment</em>
You can also write and solve an equation that shows the measures are proportional:
actual width / drawing width = (10 ft) / (1 in) = (gym width) / (7 in)
Multiplying both sides of this proportion by 7 in, we have ...
gym width = (7 in) × (10 ft)/(1 in) = 7 × 10 ft = 70 ft

Answer:
C
Step-by-step explanation:
When you cross multiply by denominator expressions that share a zero, you are effectively making that zero a solution of the resulting equation. That zero cannot be part of the domain of the original equation, and so must be an extraneous solution.
This condition is seen in choice C.
The solutions to this equation are x=1/5 and x=3. Of these, x=3 is extraneous.

A better solution method is multiplying by the least common denominator:
Answer:
A
Step-by-step explanation:
Given x < - 6
Since less than, then looking for an open circle at - 6 on the number line
If ≤ then closed circle at - 6
Also since less than - 6 we are looking for the arrow pointing to the left indicating values less than - 6 , arrow right indicates greater than - 6
The option is therefore A
