Answer: Part one (NEGATIVE) Part two is C (EVEN DEGREES OF FOUR OR GREATER)
Step-by-step explanation:
(So “/” will basically mean divide)
450/3000=0.15
0.15*100=15% rate
The third one because its the only one decreasing
Step-by-step explanation:
7+2x-2 = 4x -3
5= 2x -3
2x = 8
x = 4
Answer:
R290.1
Step-by-step explanation:
Let
x = charge before he put his prices up
New charge = R320
Percentage increase in price = 7%
x + 7% of x = 320
x + 0.07 * x = 320
x + 0.07x = 320
1.07x = 320
x = 320/1.07
x = 299.06542056074
Approximately
x = R290.1
Charge before he put his prices up = R290.1
