Answer:
$18
Step-by-step explanation:
- I multiply the tax by the pretax price of the meal, and I get 8% * x
- I multiply the tip by the pretax price of the meal, and I get 20% * x
- I make an equation, and make sure to add the original x
- 2/25x + 1/5x + x=23.04
- 32/25x=23.04
- x=18
- Therefore, the pretax price of the meal is $18
To convert a quadratic<span> from y = ax</span>2<span> + bx + c form to </span>vertex<span> form, y = a(x - h)</span>2+ k, you use the process of completing the square. Let's see an example. Convert y = 2x2<span>- 4x + 5 into </span>vertex<span> form, and state the </span>vertex<span>.</span>
I hope this helps you

Answer:
x = 8
Step-by-step explanation:
Corresponding segments are proportional.
(3x +1)/10 = (7x -1)/22
11(3x +1) = 5(7x -1) . . . . . . multiply by 110
33x + 11 = 35x -5 . . . . . . eliminate parentheses
16 = 2x . . . . . . . . . . . add 5-33x to both sides
8 = x . . . . . . . . . . divide by 2
