The number you are looking for is 12. Reversing the digits gives you 21 75% of 12 is 9 12 + 9 = 21
6(n+12) + 3(n+6) = 58.5 6n + 72 + 3n + 18 = 58.5 9n + 90 = 58.5 9n = 58.5 - 90 9n = -31.5 n = -3.5
26 + 12*n
-12 + 75 = 63 So if minus 12 is increased by 75 the new number is 63 If the question was 75 percent, the number would be 36.
26+12n
x + (-12) = 28 So x = 28 + 12 = 40
If 8 is increased to 12, the increase is what percentage of the original number?
There are two possible (and different) answers: 2x + 3y = 12 or 2*(x + 3y)= 12 The first one is (twice a number) increased by (three times another) The second is twice (a number increased by (three times another)).
39
22 12+2x = 33 2x = 33-22 = 11
28.5 increased by 12 is 40.5. 28.5 increased by 12% of itself is 31.92.
Call the number I am thinking of W ( for WikiAnswers) 2W+12=30 So 2W=18 W is 9 The number is 9
86 which upside down looks like 98. Difference between them is 12
