We have that
tan x=5
we know that
tan x =sin x/ cos x
sin x/ cos x=5------> squaring-----> sin² x/cos² x=25
remember that
sin² x+cos² x=1-----> cos² x=1-sin² x
substitute
sin² x/[1-sin² x]=25
sin² x=25-25*sin² x
26*sin² x=25
sin² x=25/26
sin x=5/√26
cos² x=1-(5/√26)²----> 1-(25/26)----> 1/26
cos x=1/√26
the answers are
sin x=5/√26
cos x=1/√26
$25 per item sold + $100 per week = 700 total goal in 1 week
X is our items sold variable. We only use 100 since our goal is for only one week.
25x + 100 = 700
Subtract 100 from each side.
25x = 600
Divide by 25.
x = 24

Answer:
x+16y
Step-by-step explanation:
4x-2(4x-6y) + 1/2(10x +8y)
4x-8x+12y+5x+4y
