Since we see that sides AD and DC are equal, as well as sides BE and EC, we can use this information to conclude that the value of 2x-7 is equal to double the value of DE.

2x - 7 = 4(2)

2x - 7 = 8

2x - 7 + 7 = 8 + 7

2x = 15

x = 7.5

Answer: Step 4

<u>Step-by-step explanation:</u>

1. Define variable x as student signatures still needed (Correct)

$2)\ \dfrac{x+82}{426}$ (Correct)

3. 25% = 0.25 (Correct)

$4)\ \dfrac{x+82}{426}\leq 0.25$ (Error)!
