x + y +z = 6..........(1)

z = x + y...............(2)

x = z + 1................(3)

from  equation (2) :-

x + y = -z

Subtracting this from equation (1) :-

z = -z  + 6

2z =  6  so z = 3

From equation (3) :-

x = 3 + 1 =  4

And from equation (1):-

4 + y + 3 = 6

y = 6 - 7 = -1

Answer  x = 4, y = -1 and z = 3.

How should I solve this to get the elapsed time
8090 [49]

Answer:

Subtract the hours to get 12-3 = 9

Or you could start at 3 PM, and count your way up one hour at a time, until you get to 12 AM. You should count out 9 hours in total.

An alternative is you could note from 3 PM to 3 AM is a span of 12 hours. Take 3 hours away from 3 AM, and you'll rewind the clock back to 12 AM. So 12-3 = 9. :-)

plz brainlist plz ;-)

Please help me, I’ll mark your answer as brainliest! <br> Find g(x)
KengaRu [80]

Answer:

|x-3|-5

Step-by-step explanation:

f(x) = |x|

These lines are lines of absolute value equations. g(x) is shifted 3 units left so we subtract 3 from within the bars, and shifted down 5 units so we subtract 5 from the absolute value which leaves us with |x-3|-5
