6. homer and bart plan to buy one computer for $499.00 strictly for gam purposes. games cost $49.99 each. part a: define each variable and write an algebraic expression to describe how much they will spend before sales tax, based purchasing the computer and the number of games.

The required algebraic expression is where x is the number of games and y is the total cost.

Step-by-step explanation:

Consider the provided information.

It is given that the cost price of computer is $499.00

Let x represents the number of games Homer and Bart bought and y is the total purchasing cost of the computer (before sales tax).

It is given that the cost of each game is 49.99.

If they bought x games, then the total cost will be:

Therefore, the algebraic expression is where x is the number of games they bought and y be the total cost.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.
