Given :
John can play 12 songs on his guitar but learns 1 new song every week. Aiden can play 4 songs but learns 2 every week.
To Find :
How many weeks will it be before Aiden knows as many songs as john?
Solution :
Let, after x weeks Aiden know a songs and John know j songs.
The linear equation for both the situation is :
a = x + 12 .....( For Aiden )
j = 2x + 4 ......( For John )
We need to find in which week Aiden knows as many songs as John.
For this , a = j
x + 12 = 2x + 4
x = 8
Therefore, in 8th week both of them know the same number of songs.
Answer:
2(j+2)
Step-by-step explanation:
Since 2 is the GCF, you should take out 2 to make the answer 2(j + 2).
Answer:
I think the answer is x = 13/3
Step-by-step explanation:
Answer:
You need to use the angles as a waypoint such as the one opposite b is equal to b then you need to use the angles on a straight line
Step-by-step explanation:
Answer: The experimental probability of 2/9
Step-by-step explanation:
2/18= 1/9 * 2= 2/9 so on the first try,she sold 2 out of 18 which means the experimental probability is 2/18 = 1/9 so since this is the second try, you will have to multiply 1/9 by 2 to find the next possible outcome.
