Help me pls subtract 28.9 -9.25

19.65

Step-by-step explanation:

you line 28.9 with 9.25 below it and then you subtract it. take it one column at a time.

28.9

-  9.25

the imaginative zero becomes 10 and then the 9 becomes an 8 so 10-5=5 and 8-2=6

then you subtract 9 from 28 and get 19

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

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.
