90%

Step-by-step explanation:

So Sally gets 18/20 of the questions correct then you need to make the denominator of the fraction to 100 which makes a percent. So you multiply both the numerator and denominator by 5:

90/100

which is equal to 90%

Extract common factor "a":

a(b + 3c) = -2

Divide by the term (b + 3c):

$a = \dfrac{-2}{b+3c}$
