1) 40-25= 15
2) 15/3=5
3) each gift costs $5
Then to check:
1) 5x3=15
2) 25+15=40
Therefore p=5
Answer:
The number is 6
Step-by-step explanation:
Let the number be x
3 times a number plus 5 = 3x +5
Same number increased by 17 = x + 17
3x + 5 = x + 17
3x -x + 5 = 17
2x + 5 = 17
2x = 17 - 5
2x = 12
x = 12/2
x = 6
Alright, so it would be helpful to think about this question in terms of units. You're given a distance (meters) and speed (meters per second). You're asked for time (which is in seconds).
If you do

, your answer will be in seconds. So divide your distance (2.28 x 10^11 meters) by your speed (3.00 x 10^8 meters/second), and you should get your time!
17 years
Step-by-step explanation:
1200/3z = 8
400=8/3 year for each building
they take 8
1600 is 2/3 year for each building
2/3 times 25 is 16.666
