Distributive property from what I recall,
I’d just say that you cannot know a method they have not thought you because they are your teachers and are expected to teach you this not to teach yourself
Answer:
100
Step-by-step explanation:
She wants to average 85, so adding ALL three of her scores, divided by 3 needs to equal 85.
(75 + 80 + x)/3 = 85
Times by 3.
75 + 80 + x = 255
155 + x = 255
subtract 155.
x = 100
She needs 100 on the third test.
