GEOMETRY The sum of the measures of angles X and Y is 180°. The measure of angle X is 24° greater than the measure of angle Y. a. Define the variables, and write equations for this situation. b. Find the measure of each angle.
Use substitution to solve each system of equations.
14. y = −3x + 4 −6x − 2y = −8
16.x =y −1 −x + y = −1
18. y = −3x + 1 2x + y = 1
Please help my teacher gave me homework on a Sunday ;(

Someone answer this asap for gabriella uses the current exchange rate to write the function, h(x), where x is the number of u.s. dollars and h(x) is the number of euros, the european union currency. she checks the rate and finds that h(100) = 7.5. which statement best describes what h(100) = 75 signifies? a. gabriella averages 7.5 u.s. dollars for every 100 euros. b. gabriella averages 100 u.s. dollars for every 25 euros. c. gabriella can exchange 75 u.s. dollars for 100 euros. d. gabriella can exchange 100 u.s. dollars for 75 euros.
