Answer:
Below in bold.
Step-by-step explanation:
x /18 = 12/10
10x = 18*12
x = 216/ 10
= 21.6.
10/w = 18/24
10/w = 3/4
3w = 40
w = 40/3 = 13 33 to the neaest hundredth.
Option B:
is the value of y
Explanation:
It is given that "Two times x is 8 more than y". Writing it as expression, we have,

It is also given that "The sum of x and two times y is 14". Writing it as expression, we have,

To find the value of y, let us solve the two equations using substitution method.
From the equation
, let us find the value of x.



Now, substituting
in the equation
, we get,





Thus, the value of y is 
Volume of Cylinder
= πr²h
= (3.14)(5)²(16)
= 1256 cm³
Volume of Cone
= 1/3πr²h
= 1/3(3.14)(4)²(12)
= 200.96 cm³
Volume of air space
= Volume of Cylinder - Volume of Cone
= 1256 - 200.96
= 1055.04 cm³
≈ 1055 cm³ (nearest whole number)
