Ms. Adelle polled her students to find out how long they studied for their last math test. She then recorded the number of questions answered correctly by each student based on those results.

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925

table 3 represents a direct variation function. : )

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
