The solution of - t/18 ≥ 10 is t ≤ -180 true or false?

True

Step-by-step explanation:

given - ≥ 10 (multiply both sides by 18 )

- t ≥ 180 ( multiply both sides by - 1)

Remembering to reverse the symbol as a consequence of multiplying by a negative quantity, hence

t ≤ - 180

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
