Answer: 4.500
Step-by-step explanation:
4x - 18 = 2 • (2x - 9)
2 = 0
2x-9 = 0
2x = 9
x = 9/2 = 4.500
Answer:
42
6x7=42
That would be option A as the angles and sides ( the AS) have already been stated.
200 copies must be sold
n= number od newsletters
0,50*n+300=2,00*n
300=1,5*n
Divide both sides by 1,5
200=n
0,50*200+300=2*200
100+300=400
400=400
