Answer:
D.
Bob should use the mean to make his selling price look like it's the greatest.
Let that certain number be 'n'
50% (n) = 39
50% ⇒ 0.5
0.5 (n) = 39
Divide both sides by 0.5
0.5n = 39
/0.5 /0.5
n = 78.
So that certain number is actually <em><u>78! :)</u></em>
CROSS CHECK:
50% of 78
0.5 × 78
= 39
Hope this helps! :)

Answer:
{x | x∈ R, x < 2}
Step-by-step explanation:
Given
Open circle on 2
Arrow pointing left
Required
Determine the inequality
An open circle on 2 means represents either < or >
The arrow points to the left of -2 means that the number line represents numbers less than 2. i.e. < 2
Represent the numbers with x.
The inequality is: x < -2
Using proper notation, the inequality is: {x | x∈ R, x < 2}
