Marco's mom has sent him to the store to buy apples and oranges. She has given Marco instructions to buy 4 pounds of apples and as many
pounds of oranges as possible. He also has to spend exactly $9.11. If one
pound of apples costs $1.29 and one pound of oranges costs $0.79, how
many pounds of oranges will Marco be able to buy? Use the equation
1.29(4) + 0.79X = 9.11 to help you solve the problem.

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
