Which equation represents this number sentence? Three less than one-fifth of a number is 28. 3-1/5n=28
(3-1/5)n=28
(1/5-3)n=28
1/5n-3=28

i would say c is the best answer, hope it's right!

good luck! =)

step-by-step explanation:

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
