Answer:
a=1, b=-2,c=-1
Step-by-step explanation:
1*(x)+(-2)*y+(-1)*1. a=1, b=-2,c=-1
So, we have the percentage she gets which is, 90% and the number of questions she answers correctly, which is 27
To find the number of questions in the exam, make an equation
(90% =

= 0.9)

=

cross multiply and equate them
90x = 27 x 100
90x = 2700
divide by 90 on either sides to isolate x in order to find the answer

90 and 90 cancels out
x = 30So your final answer will be,
there were 30 questions in the exam paper.
The distance between -10 and 9 is 19 and the distance between 2 and -7 is 9
