Answer:
The initial value of 600 is larger and larger by 24.
Step-by-step explanation:
First of all a 20% decreased of 600.
So, the new value will be 
.
Now, then it is increased by 20% i.e. 480 will be increased by 20%.
So, the new value will be 
.
Therefore, the initial value of 600 is larger and larger by (600 - 576) = 24. (Answer)
9514 1404 393
Answer:
(3, 1)
Step-by-step explanation:
We assume you want the solution to the system ...
The second equation gives a nice expression for x, so we can use that in the first equation.
2(y+2) -3y = 3 . . . . substitute for x in the first equation
2y +4 -3y = 3 . . . . . eliminate parentheses
-y = -1 . . . . . . . . . . . collect terms, subtract 4
y = 1 . . . . . . . . . . . . multiply by -1
x = 1 +2 = 3 . . . . . . substitute for y in the second equation
The solution is (x, y) = (3, 1).
Answer:
13
Step-by-step explanation:
Substitute 3 into c --> 5(3)-2 = 15-2 = 13
