Conceptually, you are asking for the additive inverse of 8. By definition, in fact, the additive inverse of a number 
is a number 
such that 
You obtain the additive inverse of a number by switching its sign, so the additive inverse of 8 is -8. In fact, you have
1) Sample space of the spinner={Green, Blue, Purple, Yellow, Red}=5
2) Sample space of the cards={Red, Yellow, Blue, Pink }=4
1) P(spinner stops at purple) = 1/5
2) P(pink card selected) = 1/4
1) AND 2) are conditional probabilities:
P(spinner stops at purple ∩ pink card selected ) = (1/5)(1/4) = 1/20 =0.05
Brianna's thinking is incorrect.
Expessions A, and C. are equivalent.
For C, you add 5x and x together (because they have the same variable) to get 6x - 4.
For A, you subtract 9x and 3x (because they have the same variable) to get 6x- 4.
Answer:
Multiply 107 and 1 and then multiply 106 and 8 and then subtract them...
