Olivia measured several rooms in her house in feet. she wants to express the measurements in inches. write an equation relating feet x and inches y. tell whether the equation is linear or non-linear

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

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

-9
