The answer is 19 just draw a line with negative and positive values and you could count how much -8 is from 11
Step-by-step explanation:
RS = 11
R = -8
-8S = 11
Divide both sides by -8
8S/8 = 11/8
S = 11/8
S = 1.375
S = 1.4 to 1.dp
Depending on the number line, use to any decimal place you want to from the full answer(1.375)
