Stan wants to put a rectangular garden in his backyard. He has sketched out a plan for the garden on a grid of his rectangular backyard. The scale for the grid is 1 unit equals 3 f

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

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it

it would be c. 25 units
