447 = -6 + 3(n - 1)

Irina-Kira [14]

After solving the equation: $447 = -6 + 3(n - 1)$ the value of n is $n=152$

Step-by-step explanation:

We need to solve the equation: $447 = -6 + 3(n - 1)$ and find value of n

Solving:

$447 = -6 + 3(n - 1)$

Multiply 3 with terms inside the bracket

$447 = -6 + 3n -3\\447=3n-9$

Adding 9 on both sides

$447+9 =3n-9+9\\456=3n\\=> 3n=456$

Divide both sides by 3

$n=456/3\\n=152$

So, after solving the equation: $447 = -6 + 3(n - 1)$ the value of n is $n=152$

Helppppppppp??? Pls !!!

castortr0y [4]

Answer:

a. 19

Step-by-step explanation:

5/6x-1/5x=19

5/6(30)-1/5(30)=19

25-6=19

19=19

?/30(30)=19

19/30(30)=19

19=19

I'm not sure if this is exactly what you're looking for, but 19=19 if you plug in 19 for the box (and x=30 because of the first section, I'm guessing)
