I had to do several calculations to get the answer.
First I calculated how many points each incorrect answer decreased:
6 questions * x = 30 points => x = 30 points / 6 questions = 5 points / question.
Then I converted it in an equation of the kind:
( ) ( ) = 5
And concluded it was 1/6 * 30 = 5
So, the numbers must be placed on either of these two forms:
( 1/6 ) ( 30) = 5, or
( 30 ) ( 1/ 6) = 5.
Of course, both of them are correct answers.

Answer:
35°+95°= 130°
a triangle equals 180° so,
180°-130°=50°
and to solve for the next triangle you would have to use 50° therefore,
50°+85°= 135°
since you are now solving for the next triangle you would do 180°-135°= 45°
so your missing angle is 45°
hope that made sense
Answer:
A) 0.26
B) 0.42
Step-by-step explanation:
No. of cars which needed both:
92 + 136 - (200 - 24)
52
P(both) = 52/200 = 0.26
No. of cars that need an alternator, but not new brakes:
136 - 52
84
P = 84/200 = 0.42
