dedylja [7]
Answer:
Rocco originally had $240

Explanation:
Before we begin, note that the price of the putter is given AFTER the discount. This means that the value of the discount doesn't affect the solution.

Assume that the amount Rocco had originally is x
Now, we are given that:
price of putter = $48
Price of putter represents 20% of what Rocco had

This means that:
price of putter = 20% * amount Rocco had
48 = 20% * x
48 = 0.2x
x = 48 / 0.2
x = $240

This means that Rocco originally had $240

Hope this helps :)

Yvonne is solving the quadratic equation 6x2 + 24x + 7 = 0 by completing the square. Her first four steps are shown in the table
zaharov [31]
Step 1 should be
Bring the constant to the other side and divide the whole equation with 6 resulting to
x2 + 4x = -7/6

Step 3 should be
Complete the square by dividing the coefficient of x by 2, squaring it and adding the result to both sides of the equation.
x2 + 4x + 4 = -7/6 + 4

Step 4 should be
Factor the quadratic equation and simplify
(x+2)2 = -17/6

Step should be
Get the square root of booth sides and solve for the values of x
x+2 = +-√(102) / 6
So,
x = -2 + √(102) / 6 and x = -2 - <span>√(102) /3
