Answer: The answer is B
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
- (4n+5)-n/20=1
- cross multiply:(4n+5)-n=20
- 4n+5=20+n
- 4n-n=20-5
- 3n=15
- Divide both sides by coefficient of n
- n=5
Answer:
2400 pages
Step-by-step explanation:
Printer 1 : 50+ 1.50/30 x where x is the number of pages
Printer 2 : 10 + 2/30 x where x is the number of pages
Set them equal
50+ 1.50/30 x = 10 + 2/30 x
50 + 1/20x = 10 +1/15 x
Subtract 1/20x from each side
50 + 1/20x -1/20x= 10 +1/15 x-1/20x
50 = 10 +1/15x - 1/20x
Subtract 10 from each side
40 = 1/15x - 1/20x
Get a common denominator
40 = 4/60x - 3/60x
40 =1/60x
Multiply by 60
40 *60 = 1/60x *60
2400 =x
