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:
B. 2(20 + w) < 57
Step-by-step explanation:
Only choices B and D show something "less than 57". Of those, only choice B shows a sum of length and width.
It should be A. Normal Distribution.
The answer is 1.52 because $6.08 divided by 4 = $1.52
If f(x) = 2x+1; Prove f(3+1) =f(3)+f(1)
Proof: 2(3+1)+1 = 2(3)+1 + 2(1)
6+2+1 = 6+1+2
9 = 9
<span>Therefore: f(3+1) =f(3)+f(1)
this is NOT the answer just a question i got on my test its a example</span>
