Answer:
x = 21
Step-by-step explanation:
The 2 angles form a straight angle and are supplementary, thus
7x + 9 + 2x - 18 = 180, that is
9x - 9 = 180 ( add 9 to both sides )
9x = 189 ( divide both sides by 9 )
x = 21
Y=8x-9

Answer is $963.43
Step by step.
The computer is $890. Sales tax is 8.25%.
Multiply $890 x 8.25% (or .0825) and add that tax to the cost.
