Elisa and Katy are both traveling to Europe. Elisa paid $820 for her plane ticket and $110.50 per night for her hotel. Katy paid $1,205 for her plane ticket and $75.50 per night for her hotel.

They each spent the same number of nights in their hotels. The two women each spent the same total amount for airfare and lodging during their trips.

Set up a system of equations to model the amount of money Elisa and Katy spend on airfare and lodging during their trips. Let x represent the number of nights spent in a hotel, let E represent the total amount Elisa spends, and let K represent the total amount Katy spends.

What is the solution to the system of equations found in Part A? Give your answer as an ordered pair.

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180

lol.

it's ok we all do this sometimes.

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
