Answer:
Step-by-step explanation:
Solve for x;
2x - ( x - 2 ) = 4x
distribute minus sign through parantheses
combine like terms
subtract x from both side
- x - x + 2 = 4x - x
- 2 = 3 x
Divide each side by 3

30% of 30
Well, when doing a percentage you first turn the percentage into a decimal (move the % two units to the left). So 30% = 0.3
In math, the word of means multiplication, so: 0.3 x 30
Which equal 9.
You can also turn the percentage into a fraction, it's really up to preference.
30/100 of 30 = 3/10 of 30 = 3/10 x 30 = 3/10 x 30/1 = 9/1 or 9
Answer:
57.6 pages
Step-by-step explanation:
First, you need to identify how many minutes are in 3/5 of an hour:
1 hour = 60 minutes
3/5 of an hour = 3/5 of 60 minutes
= 3/5(60)
= 36
So, you need to find out how many pages can be printed in 36 minutes. To figure this out, a ratio can be used:
15 : 24
36 : p
p represents pages in 36 minutes.
Now, you need to solve the ratio by figuring out what you need to multiply 15 by to get 36 and then multiplying that by 24:
15 * 36/15 = 36
36/15 = 2.4
24*2.4
= 57.6 pages
