Answer:

645320

Step-by-step explanation:

Given: 6_5_2_

If a multiplication sign is placed between the second and third digit, and an equal sign is placed between the third and fourth digit, then

6_ × 5 = _2_

The passcode contains 6 DIFFERENT digits, so we know the missing numbers cannot be 6, 5, or 2.

So, do a trial and error session of multiplying 5 by numbers it could possibly be (60, 61, 63, 64, 67, 68, 69).

64 × 5 = 320. It is the only equation that is both correct and matches the digits given, so the missing digits are 4, 3, and 0. Barry's passcode is 645320.

Answer: In the exact order up to down: 80, 74, 110, 96, 80

Step-by-step explanation:

Do the equation

360=(x-6)+(x+30)+1.2x+x

we can simplify by doing

360=(x-6)+(x+30)+2.2x

=360=x-6+x+30+2.2x

=360=4.2x+24

=336=4.2x

=80=x

x=80
