The expression "12 minus r" represents the subtraction of the variable "r" from the constant 12. This operation can be simplified as 12 - r. The result is a difference, where the value of "r" is subtracted from 12.
-5 = 7 + 3r | subtract 7 -12 = 3r | divide by 3 -4 = r
If 100-r=99.52, r=100-99.52 and r=.48.
It is y - 12.
It is 1 - r/7
2/3 - 12 = -11 1/3 or minus eleven and one third.
r - 12 ≥ 5r - 12 + 12 ≥ 5 + 12r ≥ 17
-y minus 12 is 12.
3 - (-12) = 3 + 12 = 15.
12 minus -5 is 17.
-22 - 12 = -8
minus 21 think of it as 12+9 which equals 21 then just whack a minus sign infront
-5 = 7 + 3r | subtract 7 -12 = 3r | divide by 3 -4 = r
-18
It is 3/4 minus 1/3 is the same as 9/12 minus 4/12 = 5/12
That factors to 3(r - 5)(r + 1) r = 5, -1
11/12 minus 7/12 is 1/3
-12 minus -6 is -6
