A video merchant sold 24 cases of tapes, which was 20% of what he had left. What percent of tapes did he sell?
Naddika [18.5K]

Answer:

16.67% of cases of tapes were sold.

Step-by-step explanation:

We are given the following in the question:

Number of cases of tapes sold = 24

Thus is 20% of tapes left.

Let x be the total number of tapes left.

Thus, we can write:

20\%\rimes x = 24\\\\\dfrac{20}{100}\times x = 24\\\\x = 24\times 5 = 120

Thus, total number of tapes =

=24 + 120 = 144

Percentage of tapes sold  =

=\dfrac{24}{144}\times 100\% = 16.67\%

Thus, 16.67% of cases of tapes were sold.

yanalaym [24]

Answer: x = 7

Step-by-step explanation: In order for a parallelogram to be a square, the angles at the corners must be 90 degrees, and the diagonals that bisect the corner angles must be 45 degrees.

4x + 17 = 45  Subtract 17 from both sides.

4x = 28   Divide both sides by 4

x = 7
