23 x 20 x 30 = 13,800
(2/3) x (-30) = -20
20% of 30 is 6 ; 20 percent = .20 30 x .20 = 6
20 x 30 = 600 square cm
20/30 = (2 x 10)/(3 x 10) = 2/3
Surface area = 2 x area_triangular_ends + areas_of_3_rectangular_faces Surface area = 2 x (15 x 20)/2 + 30 x 15 + 30 x 20 + 30 x 25 = 15 x 20 + 30 x (15 + 20 + 25) = 300 + 30 x 60 = 2100 in2
When multiplying with zeros you just remove the zeros and multiply the other digits then add the amount of zeros you removed to the answer. 30 x 20 = 3x2 =6 then add two decimal to the right with zeros. 600 30 x 20 = 600
20% of $30 = 0.2 x $30 = $6
20
Assume your age=x x+30=2.5x 1.5x=30 x=20 I am 20.
30 feet x 20 feet = 600 square feet.
For example ?x+20=50x then solve: 50x-20=30x 30x/x=30 then the answer is 30 you just have to dived the answer by x
