The difference in the dogs weight from 2 years ago is -0.83
6x-3 is the answer because you multiply an invisible 1 by bothering the -6x and 3
The second result is more precise because it's in millilitre,so if the first were to be fully precise,it should have been 78.6 cm.
Hope this helps!
Answer:
2513.27 inches
Step-by-step explanation:
Given that:
Diameter = 20 inches
Number of revolutions = 40
For a complete revolution :
Distance traveled = Circumference = 2πr
2 * π * 20/2 = 62.831853 inches
Distance per revolution * number of revolutions
62.831853 * 40
= 2513.2741 inches
= 2513.27 inches
Answer:
The answer to your question is 3 tickets for students and 5 tickets for adults
Step-by-step explanation:
Data
Adults = a = $7.25
Students = s = $5.50
total tickets = 8
total cost = $52.75
Process
1.- Write equations for the problem
a + s = 8 --------------- l
7.25a + 5.50s = 52.75 --------------- ll
2.- Solve equation l for a
a = 8 - s
3.- Solve equation by substitution
7.25(8 - s) + 5.50s = 52.75
58 - 7.25s + 5.50s = 52.75
- 1.75s = 52.75 - 58
- 1.75s = - 5.25
s = -5.25/-1.75
s = 3
4.- Find a
a = 8 - 3
a = 5
5.- Result
3 tickets for students and 5 tickets for adults
