Brandon is running errands for his mother.
It is

1/4
mile from his house to the library and
2/3
mile from the library to the grocery store.
Brandon claims that he walks a total of
11/12
mile if he goes from his house to the library to the grocery store.
Which of the following shows whether Brandon is correct and why?

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

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

i dont know what you want me to answer for this but im guessing 2: 11?
