The new price is 52.50
30x2=60
30/4=7.5
7.5x3=22.5
22.50+30= 52.50
The correct answer is C. A linear equation is written in y=mx+b, which this equation can be. y=3-4x is the same as y=-4x+3, which is a linear function.
Answer:
Step-by-step explanation:
1. sin 30 = x/16
x= 16 sin 30
x = 8
2. cos 60 = 22/x
x = 22/cos 60
x = 44
3. tan 45 = x/19
x = 19 tan 45
x= 19
4. tan 16 = x/13
x = 13 tan 16
x= 3.73
5. sin 54 = x/45
x = 45 sin 54
x= 36.41
6. sin 35 = z/23
z = 23 sin 35
z = 13.19
