There are a total of 351 new animals that are being donated to a village. at the start of the year there are 3 cows and 42 ducks. these cows will provide 16 cups of milk each day and the ducks will lay 1 egg per day totaling to 88 servings of food each day. write a system of linear equations in standard form and solve using elimination.

i dont know sorry

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

a 90 degree rotation across the the origin followed by a reflection across the x-axis.
