Answer:
18 * 7.95 = $143.10
238.50 - 143.10 = 95.40
95.40/7.95 = 12
12 hours
3(3y+2)(y-2)
hope this helps
Step-by-step explanation:
X=e+r/d
swap both sides
e+r/d=x
subtract e from both sides
e-e+r/d=x-e
r/d=x-e
multiply d to both sides
d×r/d=x-e×d
r=x-e×d
sin b = 0.8
Since a and b are complementary angles , then
sin b = cos a = 0.8
