120
20% of 30 is 6 ; 20 percent = .20 30 x .20 = 6
20' x 6' = 120 square feet.
It's not clear whether the 6 in the question is 6 inches or 6 feet.If it's 6 inches: (20 x 20 x 1/2 foot) = 200 cubic feet = 7.41 cubic yardsIf it's 6 feet: (20 x 20 x 6) = 2,400 cubic feet = 88.9 cubic yards
x-6-x-4=10-x -10=10-x -20=-x x=20 check: 20-6-20-4=10-20 -10=-10√
Let number be x Then x - (-14) = 20 or x + 14 = 20 or x = 20 -14 or x = 6 Verification: 6 - (-14) = 6 + 14 = 20
The solution to the equation x - 6 - 20 is x - 26.
The answer depends on the units used for 6 x 20. It should be obvious to you that the answer for 6 inch x 20 inches will be very different to that for 6 yard x 20 yards, leave along 6 miles x 20 miles.,
(20!)/(14!) (6!) =(20 x 19 x 18 x 17 x 16 x 15)/(6 x 5 x 4 x 3 x 2) = 38,760
The solution to the equation x - 6 - 20 is x - 26.
138 - 20 x 6 = 18
It's not clear whether the 6 in the question is 6 inches or 6 feet.If it's 6 inches: (20 x 20 x 1/2 foot) = 200 cubic feet = 7.41 cubic yardsIf it's 6 feet: (20 x 20 x 6) = 2,400 cubic feet = 88.9 cubic yards
The LCM of 6, 12, and 20 is 60. 20 x 3 12 x 5 6 x 10
