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:
9 1/3
Step-by-step explanation:
1. Make 4 2/3 into a improper fraction
4 2/3= 14/3
2. Keep, change, flip
14/3 x 2/1
3. Multiply
14/3 x 2/1= 28/3
4. Simplify
28/3= 9 1/3
(btw keep, change, flip basically means to keep the first fraction the way it is, change the division sign to a multiplication sign, then flip the second fraction so the original denominator is the new numerator, and vise versa.)

Answer:
More than 250 miles
Step-by-step explanation:
Rental cost of company A is $80 + $0.6 per mile driven and company B also has a rental cost of $30 + $0.8 per mile driven.
To find the moment when company A rental cost matches that of company B,we have to create an equation that is ideal for both parties.
80 +0.6x = 30 + 0.8x
Where x is the number of miles traveled by both trucks.
Simplifying the above equation, we have
0.2x = 50 divide both sides by 0.2
= 250 miles is when both rental cost matches .
Therefore, the number of miles needed to be driven so as the rental cost of company A to better company B should be more than 250 miles
If u put a figure it will be more clear
