Help me please- Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks.

Step-by-step explanation:

We know that:

Work:

        4x + y = 73 cards

        9(4x + y = 73 cards)

        36x + 9y = 73 x 9 cards

This means that 1 premade deck is worth 37 cards. Now, let's substitute the value of y into the first equation to find x.

Hence, one booster pack is worth 9 cards and one premade deck is worth 37 cards.

Hoped this helped.

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
