There is not a difference between 12 and 12 R clothes. The size 12 R stands for 12 regular. A women's size 12 clothing item is typically wider than a regular size 12.
12r + 4 = 112, 12r = 108, r = 9
12r - 20
To simplify the expression (12r - 8 - 12), combine the constant terms (-8) and (-12). This results in (12r - 20). Therefore, the simplified answer is (12r - 20).
12r-20
It is 12r - 20 or 4*(3r - 5)
The expression is: 12r-20 when simplified
-6r-5 = 7-12r 12r-6r = 7+5 6r = 12 r = 2
12r - 15s - r + 3s = 11r -12s
-1
-1r
- 6r - 5 = 7 - 12r add 12r to both sides 12r - 6r - 5 = 7 - 12r + 12r 6r - 5 = 7 add 5 to both sides 6r - 5 + 5 = 7 + 5 6r = 12 divide both side integers by 6 r = 2 ---------- check in original equation -6(2) - 5 = 7 - 12(2) - 12 - 5 = 7 - 24 - 17 = - 17 checks
To simplify the expression (12r + 5 + 3r - 5), combine like terms. First, combine the (r) terms: (12r + 3r = 15r). Then, combine the constant terms: (5 - 5 = 0). Thus, the simplified expression is (15r).
