The Spanish Club is selling plates of food as a fundraiser. A plate with 2 tacos, 2 cheese enchiladas, and 1 tamale costs $8.50. A plate with 3 tacos, 2 cheese enchiladas, and 2 tamales costs $13.00. A plate with 1 taco, 3 cheese enchiladas, and 2 tamales costs $11.25. If x represents the costs of a taco, y represents the cost of an enchilada, and z represents the costs of a tamale, which formulated system of three equations in three variables correctly represents the cost for each taco, enchilada, and tamale?

days of the week

step-by-step explanation:

javier earned more money then kyle, so that won't always be a constant term, but the days of the week do not change so that term is always constant.

edit: i meant

45

step-by-step explanation:

what is the rest of the question? ?

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
