Answer:
12.2 12.3 12.4 12.5
Step-by-step explanation:
Answer:
the 2nd answer (II)
Step-by-step explanation:
1 and 2 are not rational if that's what your asking
N/4 < -1 — we can multiply both sides with 4, so we dont have to deal with fractions.
N < -4
So, our N goes left from -4 on a number line.
-10x<-100 — divide both sides by 10
-x < -10
x > 10
X is from 10 rightwards.
5x>20 — divide both sides by 5
x > 4
X is rightwards from 4.
I'd say (a) = 52.5 minutes or 52 minutes and 30 second
(b) = 45 minutes
