Decimal
To convert a percentage to decimal, you move the decimal point 2 places to the left. 600% - 6.0
Fraction
To convert a percentage to a fraction, divide the percentage by 100. 600/100 = 6/1 = 6
The matrices are
S =(4 11 T= ( -8 11
-3 -8) 3 4 )
Inverse of a matrix is a matrix derived from another matrix such that if you pre- multiply it with the original matrix you get a unit matrix.
if we multiply S and T
ST will be
( 4 11 × (-8 11 = ( 1 0
-3 -8) -3 -4) 0 1)
and also TS
( -8 11 × (4 11 = ( 1 0
-3 -4) -3 -8) 0 1)
therefore, matrices S and T are inverses of each other because ST = TS= I

Answer:
5 hours
Step-by-step explanation:
75 + 55x = 350
75 - 75 + 55x = 350 - 75
55x = 275
x = 5
The answer is 7.3. Hope that helps.
