Step-by-step explanation:
Your first step would be to rewrite the numbers into an easier to understand form like fractions, 45/3 and 27/3. Then you divide both numbers by 3, so you get comparable numbers. 45/3= 15, 27/3=9.
Answer:
D) 50+31.5x
Step-by-step explanation:
10% of 35 is 3.5
35-3.5=31.5
Answer:
x=−5/2,6
Step-by-step explanation:
So if the printer can print 27 pages in 4.5 minutes, then how much time does it need to print 324 pages?
The equation looks like this:
4.5/27 = ?/324
To find the value of ? divide 324 divided by 27 which equals 12. Then multiply 12 x 4.5 because to keep the equivalent, you must do the same to the top as you did the bottom. 12 x 4.5= 54
Answer: So, to print 324 pages, 54 minutes is needed.
4.5/27 = 54/324
I hope this helps:)
