8 nickels

Step-by-step explanation:

To find the amount of nickels, we can use system of equations. Let's use n for nickel and d for dimes.

Equation 1

n+d=30

This equation comes from the total amount of coins.

Equation 2

0.05n+0.1d=2.6

This equation comes from the worth of the nickels and dimes added together.

To the amount of nickels, we can use elimination method.

0.1n+0.1d=3

0.05n+0.1d=2.6

Now that the dimes are equal, we can subtrace the equations.

0.05n=0.4

n=8

There are a total number of 8 nickels.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
