Question

Use the formula d = ( r − c ) t to find c if d = 6 , r = 4 , and t = 2 . c=

Answer 1

First, we are going to want to plug in the values we are given. In this case, we will end up with the equation:

`6 = (4 - c) 2`

From here, we can solve the equation to find
`c`:

`6 = 2(4 - c)`

• Apply the commutative property to rearrange the terms on the right-side of the equation to make the distributive property more apparent

`6 = 8 -2c`

• Apply the distributive property

`-2 = -2c`

• Subtract 8 from both sides of the equation

`1 = c`

• Divide both sides of the equation by -2

We have found that c = 1.
