Solve<br> F = C + 32 for C
muminat
To solve an equation for a variable, you must isolate the variable on either side of the equation. To do this, simply subtract 32 from both sides of the original equation:

F ( – 32 ) = C + 32 ( – 32 )
F – 32 = C

We have proven that C is equal to (F – 32). This equation (bold) is the answer to your problem.

I hope this helps!

Express in the form 1:n<br> 3:12
Troyanec [42]

Answer:

1:4

Step-by-step explanation:

Given

3: 12

To express in the form 1:n

Consider how to make 3 equal to 1, we simply divide 3 by 3 to get 1 as such, we would also divide 12 by 3

3:12

= 3/3:12/3

= 1:4

Comparing with 1:n, it is safe to say that n = 4
