Answer:

<h3><u>5x</u> is the right answer.</h3>
subtract 3 from both sides to isolate the variable
Z + 3 -3 = -6 -3
Z + 0 = -9
Z = -9
Answer:
4 17/18
Step-by-step explanation:
you make the mixed numbers into improper fractions then you subtract them
Volume (V) of a cylinder is the area of circular base (pi×r^2) times it's length/height (h):

h = 20.5 ft
diameter (d) = 1 1/5 × h, 1 1/5 = 6/5 = 1.20
d = 1.20 × 20.5 = 24.6 ft
radius (r) = 1/2 d = 24.6/2 = 12.3 ft
