(x-7)/12 = x/15 x-7 = 0.8x 0.8x-x = -7 -0.2x = -7 x = 7/0.2 >x = 35<
3 - 8 + 12 = x -5 + 12 = x 7 = x Answer : 7
lcm(7, 12, 14) = 84 Using prime factorization: 7 = 7 12 = 2² x 3 14 = 2 x 7 lcm = 2² x 3 x 7 = 84
7 multiplied by 12 (7 x 12) = 84
84/7 = 12, so 12 x 7 = 84
7 x 7 x 7 = 343 12 x 12 x 12 = 1,728 7/12 x 7/12 x 7/12 = 343/1,728
X plus 7-12?
2:7::12:x Divide the '12' by '2' and multiply by '7' Hence 12 x 7 / 2 6 x 7 = 42 Hence 2:7::12:42

The same way you divide positive exponents like ( x^-7 ) / ( x^-12) = x^( -7 - - 12) = x^( -7+12) = x^5
The same way you divide positive exponents like ( x^-7 ) / ( x^-12) = x^( -7 - - 12) = x^( -7+12) = x^5
(46 x 12) x 7 = 46 x (12 x 7)
(x-7)/12 = x/15 x-7 = 0.8x 0.8x-x = -7 -0.2x = -7 x = 7/0.2 >x = 35<

-12 x 7 = -84.
You write exponents by multiplying a number by itself. Some examples: 75 = 7 to the 5th power, which means 7 multiplied by itself 5 times: 7 x 7 x 7 x 7 x 7 = 16,807 83 = 8 to the 3rd power, which means 8 multiplied by itself 3 times: 8 x 8 x 8 = 512 126 = 12 to the 6th power, which means 12 multiplied by itself 6 times: 12 x 12 x 12 x 12 x 12 x 12 = 2,985,984
3 - 8 + 12 = x -5 + 12 = x 7 = x Answer : 7
