Let lowest possible score be x (66+ 80+ 88+ 82 +72+ x)/6=80 on solving we get ans as 92
Answer:
<h2>x = -8/3</h2>
Step-by-step explanation:
6x + 20 = -4
subtract 20 from both sides
6x = -16
divide by 2
3x = -8
<h2>x = -8/3</h2>
4+5s+6-2s = 0 Combine Like Terms
10+3s = 0 Subtract 10 from both sides
3s =- 10 Divide both sides by 3
s = (-10/3)
