For basketball tryouts, Lia ran two laps in a total of 27.5 seconds. In the second lap, she beat her first lap by 3 seconds. How long did it take Lia to run the first lap? How long does it take to run the second lap? (Algebra 1, use BUB way. AKA equations. EX: “2x-7=8” but the questioned numbers)

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

2x + 8
