Answer: 1.6 N/cm^2
Step-by-step explanation:
3x - y = 10 . . . (1)
-x + y = 12 . . . (2)
(1) + (2) => 2x = 22 => x = 22/2 = 11
From 2, -11 + y = 12 => y = 12 + 11 = 23
150 minutes : 3 1/2 hours
3 1/2 hours = 3.5 hours = 3.5 * 60 = 210 minutes
150 minutes : 3 1/2 hours = <span>150 minutes : 210 minutes
</span>
= 150:210
= 15 : 21
= 5 : 7
