Answer:
3
Step-by-step explanation:
2(x + 1) = 3(5 - x) + 2
Distribute,
2(x + 1) = 3(5 - x) + 2
2x + 2 = 3(5 - x) + 2
Rearrange terms,
2x + 2 = 3(5 - x) + 2
2x + 2 = 3(-x + 5) + 2
Distribute,
2x + 2 = 3(-x + 5) + 2
2x + 2 = -3x + 15 + 2
Add the numbers,
2x + 2 = -3x + 15 + 2
2x + 2 = -3x + 17
Subtract 2 from both sides,
2x + 2 = -3x + 17
2x + 2 - 2 = -3x + 17 - 2
2x = -3x + 17 - 2
2x = -3x + 15
Add 3x to both sides,
2x = -3x + 15
2x + 3x = -3x + 3x + 15
5x = -3x + 3x + 15
5x = 15
Divide both sides by the same factor (15),
5x = 15
5x/5 = 15/5
x = 15/5
x = 3
Hence, the answer is 3.

Step-by-step explanation:
She forgot to multiply 14 with -13
It would be 1/3rd because your last number would be 4 in the equation of 12 sandwiches.
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
