Answer:
The value of x , y using substitution method is 2 , 5
Step-by-step explanation:
Given as :
The two linear equation as
6 y - 4 x = 22 .......1
y + 2 x = 9
Let y = 9 - 2 x .......2
Now, using substitution method
Substitute the value of y from eq 2 into eq 1
i.e 6 × (9 - 2 x) - 4 x = 22
Or, 54 - 12 x - 4 x = 22
Or, 12 x + 4 x = 54 - 22
Or, 16 x = 32
∴ x =
i.e x = 2
Now, Put the value of x into eq 2
∴ y = 9 - 2 x
So, y = 9 - 2 × 2
Or, y = 9 - 4
i.e y = 5
So, The value of x , y = 2 , 5
Hence, The value of x , y using substitution method is 2 , 5 Answer
15 performances can be accommodated
<em><u>Solution:</u></em>
Given that,
Each performer for the talent show has 7 minutes for his or her performance
The introduction for the talent show is 25 minutes long
The entire show including the introduction, will last 130 minutes
Thus the remaining time for performances is:
Performance time = 130 minutes - 25 minutes
Performance time = 105 minutes
To find, the number of performances, divide the 105 by 7 minutes
Thus 15 performances can be accommodated
