180/20=9
9*20=180
a + 3a + 5a = 180 9a =180 a = 20
Algebraically, with X = ' what. '30X = 180X = 180/30X = 6=====

100+80, 99+81, 98+82....
As a product of its prime factors: 2*163 = 326
20 times 3 equals 60
2 times 90 equals 180
To solve this one, subtract 50 from 180 and you'll have your answer.
15 times 12 = 180
4x45 = 180
20 times 9 is 180.
It is 30 times 6 equals 180
4 x 45 = 180
5 x 36 = 180
7.2 x 25 = 180
180/40 which is 4.5
10 x 18 = 180
