If a = -15, b = 5 and c = -2 a - b - c = -15 - 5 - (-2) = -20 + 2 = -18
18 times 20 equals 360.
-15 plus 20 is 5.
Nope> One is two thirds while the other is nine tenths.
138 - 20 x 6 = 18
18 + 10 + 20 + 30 + 15 + 50= 143
If a = -15, b = 5 and c = -2 a - b - c = -15 - 5 - (-2) = -20 + 2 = -18
Option D *Rounding 18 to 20, and 20x20=400
18 times 20 equals 360.
Negative 15 plus positive 20 equals 20 minus 15, which equals 5.
20 = 400
-15 plus 20 is 5.
-20
Nope> One is two thirds while the other is nine tenths.
138 - 20 x 6 = 18
If: m = 20 Then: 3m+18 = 78
If: x+18 = 20 Then: x = 2
