17-20. Which numbers will come out of the machine?
12, 20, 30, 22 [×3] [-5] _, _, _, _.
To determine the numbers that will come out of the machine, we need to follow the given operations: multiplying by 3 and then subtracting 5.
Starting with the given numbers:
12 * 3 = 36 - 5 = 31
20 * 3 = 60 - 5 = 55
30 * 3 = 90 - 5 = 85
22 * 3 = 66 - 5 = 61
So the numbers that will come out of the machine are:
31, 55, 85, and 61.
