In a simple word, a line that is crooked, or slanted. Like this: /
6x + 9 < 63
Subtract 9 from both sides.
6x < 54
Divide 6 by both sides.
x < 9
To find the final cost you multiply 35.80 x .07 and you get 2.506 but since its money you round it to $2.51. $2.51 is your sales tax and now you need to add it to the cost of the shirt so 35.80+2.51= $38.31
6% because 0.06 is representing 6 so if you just add the sign of percent then u get your answer
8.) Area= 22 squared, Perimeter= 26
9.) Area= 44 squared, Perimeter= 30
