Switch up the equation by subtracting.

9-(8*n)=0

Solve : -8n+9 = 0

Subtract 9 from both sides of the equation :

-8n = -9

Multiply both sides of the equation by (-1) : 8n = 9

Divide both sides of the equation by 8:

n = 9/8 = 1.125

Subtract 9 from both sides

9=8n
-9 -9

So the 9 cancels itself out

Then do 8-9=-1

-1n

Then -1/-1 to cancel out the -1 and get the n alone

n=1 or leave it as -1/-1

Answer

8.5

Step-by-step explanation:

43 - 3d = d + 9

43 = d + 3d + 9

43 - 9 = 3d + d

34 = 4d

34/4 = 4d/4

8.5 = d

btw its a bit rude just to delete my answer you shouldve just asked for me to show an explanation

Jane Marko buys a car for $43,900.00. in three years, the car depreciates 48% in value. How much is the car worth in three years

Oduvanchick [21]

<span>So we want to know what is the value of the car after three years if the car depricates in value for 48% and we know that the initial value of the car is 43900$. So if the price depricates for 48%, that means the new value is 52% of the initial value so: 43900$*0.52=22828$. So C is the correct answer.</span>

1/4 - 3/5 write your answer is simplest form

blsea [12.9K]

First, you put each fraction into its greatest common denominator:
5/20 - 12/20. This then gives you the answer - 7/20.
