Answer: PD = 6

Step-by-step explanation:

PD = PB + AB = 12

When two secant lines intersect each other outside a circle, the products of their segments are equal. This is:

PB x PA = PD x PC

7 x 12 = PD x 14

PD = 7 x 12 / 14

PD = 6

Jesse uses this expression to determine how much to pay, including tax and tip, when he goes out to a restaurant:
lana66690 [7]

Answer:

x is the price of the meal

(1+0.0825 + 0.18) is the total percentage on top of the price he pays with sales tax and tip.

Step-by-step explanation:

The factor x is the price of the meal. The factor (1 + 0.0825 + 0.18) is the 100% of the price, the sales tax on that price and the tip on the total. 1 + 0.0825 + 0.18 = 1.2625 is the total percentage he pays on the price. He pays 26.25% in addition of the price of the meal to cover tax and tip.
