Mike bought lunch for himself and two of his friends. Each of the meals cost $10.95 and the drinks were $1.95 each. He left a 15% tip on the table, based ONLY on the bill BEFORE tax, and then paid the bill at the cash register which included the 7% sales tax. How much did the meal end up costing him?

step-by-step explanation:

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
