Use the formula d = ( r − c ) t to find c if d = 6 , r = 4 , and t = 2 . c=
Minchanka [31]

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.

Evaluate 5+ (-11) - (-11)
SOVA2 [1]

Answer:

5

Step-by-step explanation:

To solve a problem with negatives, we use the following rule.

If it is like

x+(-y), it is equivalent to x-y

If the equation is like

(-x)-(-y), it is equivalent to (-x)+y

So,

5+(-11)=5-11=-6

(-6)-(-11)=(-6)+11=5

Your answer is 5.
