Question

Using the formula y=ab/2c, express: the variable c in terms of a, b, and y.

Answer 1

c=ab/2y

Explanation:

y=ab/2c

to get rid of the denominator we divide by 2c.

(y=ab/2c)2c

2cy=ab

now we need to get rid of the 2y from the c to isolate it. in order to do this, we must divide by 2y.

Doing this we get c=ab/2y

Answer 2

9514 1404 393

Answer:

c = (ab)/(2y)

Explanation:

The given equation can be multiplied by c/y to solve for c.

`y=(ab)/(2c)\\\\y\cdot(c)/(y)=(ab)/(2c)\cdot(c)/(y)\\\\\boxed{c=(ab)/(2y)}`

Comment on the form of the answer

When the answer is written in plain text, the fraction bar no longer serves as a grouping symbol. Hence, parentheses are needed around the denominator:

c = ab/(2y)
