Suppose y varies directly with x. write a direct variation equation that relates x and y .y=7 1/2 when x=3

Step-by-step explanation:

We know that y varies directly with: ∝ .

To convert this proportionality into an equality, we need a constant .

=

We know that when so we can write it as:

=

=

Now that we know the value of the constant is equal to   , we can write the this relation as:

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
