Which expression can be used to convert 22 Austrailian dollars to US dollars? Assume 1.2 Austrailian dollars equals 1 US dollar. $22 AUD x 1.2USD/1 AUD

$22 AUD x 1 USD/1.2 AUD

$1.20 AUD x 1 USD/1.2 AUD

$1.20 AUD x 1.2 USD/1 AUD​

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

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
