33x7=231
7560 945 = 33 x 5 x 7 1512 = 23 x 33 x 7 lcm = 23 x 33 x 5 x 7 = 7560
33 x 7 = 231
1512. 54 = 2 x 33 56 = 23 x 7 lcm = 23 x 33 x 7 = 1512
Yes. Prime factorization: 189 = 33*7. This means: a) The above equation is true. b) Only prime numbers are used (except in exponents).
x + 7y = 33 (1) --> x = 33 - 7y (1a) 3x - 2y = 7 (2) To solve the simultaneous equations, starts by substituting the value for x found in (1a) into (2): 3(33 - 7y) - 2y = 7 99 - 21y - 2y = 7 -23y = -92 y = 4 Now substitute this value for y into (1a) and solve for x: x = 33 - 7(4) x = 33 - 28 x = 5 Therefore these equations have the solution x = 5, y = 4
135 = 33 x 5 189 = 33 x 7 135/189 = 5/7
33 x 7 = 231
x=y/7
2x + 7 = 33 2x = 33 - 7 2x = 26 X = 26/2 X = 13
In index form, 378 = 2 x 3 x 3 x 3 x 7 = 2 x 33 x 7
1 x 231, 3 x 77, 7 x 33, 11 x 21, 21 x 11, 33 x 7, 77 x 3, 231 x 1.
