Hi there!
18 is 20% of 90. Why, you may ask?
To solve we just divide both sides by 0.2
We would start off with 0.2x = 18.
NOW divide.
x = 90.
We can check this by seeing that 20% of 90 is equal to 18.
Hope this helps!

Answer:
D -13
Step-by-step explanation:
5x - 3y - z if x = -2, y = 2, and z = -3
5x - 3y - z =
= 5(-2) - 3(2) - (-3)
= -10 - 6 + 3
= -16 + 3
= -13
