Answer:

Step-by-step explanation:

2) 8=n+3/-2

we cross multiply

n+3=8*(-2)

n+3= -16

n= -16 - 3

n= -19

lets check if we are correct

8=-19+3/-2

8= -16/-2

-16/-2=8

4) 9=x/2+6

we first calculate the fraction

x/2+6

L. c. m is 2

x/2+6/1=4x + 8/2=12x/2

2 times 2=4 plus x = 4x

2 times 1 =2 plus 6= 8

thats how i got 4x + 8/2

back to the question

9=12x/2

cross multiply

12x=9*2

12x=18

x=18/12

we will use 2 to divide it

9/2

3 will divide

3/2

x=3/2

Solve the Fahrenheit equation for Celsius

The first step you should do is subtract 32 from both sides so your answer will turn out like this -

F = (9/5) C + 32
-
F - 32 = (9/5)

Then we will multiply both sides by 5.

5 ( F - 32 ) = 9 C

Divide both sides by 9 to isolate C.

(5/9) ( F - 32 ) = C

So the answer is :

C = (5/9) ( F - 32 )

Hope this helps :)
