Plug 2 in for n and then solve.

anonymous · Answer

so its 20-5x2

anonymous · Answer

Yep. Now just simplify that expression.

anonymous · Answer

15

hero · Answer

Let n be the number of quizzes. If n = 2, then

20 - 5n = 20 - 5(2) = 20 - 10 = 10

Therefore, if Brandon takes two quizzes, he will accumulate 10 incorrect answers.

how its ten doe if half of 30 is 15

hero · Answer

What kind of math are you doing? You have to apply order of operations. There's a minus sign between the 20 and the 5n

hero · Answer

20 - 5n 
= 20 - 5(2)
= 20 - 10
= 10
