Select the equation that most accurately depicts the word problem. Mary Lou has 2 more nickels than pennies, and she has 30 coins all together. Use x for the number of pennies.

2x + 30 = 5
x + (x + 2) = 30
2(x + 2) = 30

The equation that most accurately depicts the word problem is:

x + (x + 2) = 30

This equation represents the fact that Mary Lou has 2 more nickels than pennies and 30 coins all together.

Let x be the number of pennies. Then, the number of nickels is x + 2. The total number of coins is the sum of pennies and nickels:

x + (x + 2) = 30

Simplifying the equation:

2x + 2 = 30

Subtracting 2 from both sides:

2x = 28

Dividing both sides by 2:

x = 14

Therefore, Mary Lou has 14 pennies and 16 nickels.
