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

Option 2 is correct.i.e., Equation that most accurately depicts the word problem is x + ( x + 2 ) = 30

Step-by-step explanation:

let x be no of pennies and y be no of nickles.

Mary Lou has total 30 coins all together means,

x + y = 30

⇒ y = 30 - x (1)

Mary Lou has 2 more nickles than pennies means,

y = x + 2

30 - x = x + 2    (from eqn (1))

30 = x + x + 2

x + ( x + 2 ) = 30

Therefore, Option 2 is correct.i.e., Equation that most accurately depicts the word problem is x + ( x + 2 ) = 30
