2.7/6=x/18
2.7 x 18 = 6x
48.6 = 6x
8.1= x

A is correct:
Let volume v, length l, and h height.
v= (l²h)/3
v=(x²9)/3
v=3x²
2 1/2 = 2.5
12 1/2 = 12.5
This means you can calculate how may times it goes in by dividing it and rounding the number down:
12.5 / 2.5 = 5
*5 can not be rounded down so it stays the same
This means that 2 1/2 goes into 12 1/2 5 times. Hope this helps! :)
19x - 11 = 10x + 7
9x = 18
x = 2
19x - 11 = 19(2) - 11 = 27
3y + 27 = 180
3y = 153
y = 51
answer
x = 2 and y = 51
