Paula weeded 40% of her garden in 8 minutes. how many minutes will it take her to weed all of her garden?

It would take her 20 minutes to weed her entire garden

Step-by-step explanation:

We can find this by taking the amount of time it took and dividing that by the percentage of the total garden that got weeded in that time.

8mins/40% = 20 mins

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
