Weekend just includes Saturdays and Sundays, so you don't have to count the earnings on Friday. You simply have to count the number of hours that passed from 7 am to 11 pm on Saturday. That would be a total of 16 hours. While on Sunday, the time from 9 am to 9 pm is a total of 12 hours. Hence, the total time would be 16 hours + 12 hours = 28 hours
Gross Wage = $20(28 hours) = $560
Answer: The numbers are -3 and - 6
Step-by-step explanation:
Let the first number be x and the second number be y , then from the first statement we have
x + 3 = y ............. equation 1
From the second statement
2y = 3x + 12 ............ equation 2
solving the resulting simultaneous equation by substitution method ,we have:
substitute x - 3= y into equation 2 , we have
2( x + 3) = 3x + 12
2x + 6 = 3x + 12
2x - 3x = 6
x = -6
substitute x = - 6 into equation 1 , that is
- 6 + 3 = y
Therefore ,
y = -3
2y = 3y + 3
Check:
x + 3 = y , implies
-6 + 3 = -3 = y
Also 2y = 3x + 12 , implies
2(-3) = -6
3(-6) + 12 = -6
Answer:
True
Step-by-step explanation:
system can be as small as two atoms colliding, as large as the entire universe.
System : it is the quantity of matter that is bounded by a boundary, of some fixed matter, which is under observation for changes.
We can fix anything to everything as our system, we want to observe and work on it.
The whole universe can also be considered as a system, which is isolated.
This is because, mass is always conserved and the entropy of this system(universe) is always increasing as there are a number of irreversible processes taking place in the universe.
Two atoms colliding can also make upto a system, if we want to observe the changes in the thermodynamical properties taking place in that system.
