The pack of pencils weighs 21.6 grams because 0.9 times 24 is 21.6
(-3,7)(9,5)
midpoint formula : (x1 + x2)/2 , (y1 + y1)/2
(-3 + 9)/2 , (7 + 5)/2 = (6/2, 12/2) = (3,6) <==
Answer:
<h2>x = 4, y = 3 → (4, 3)</h2>
Step-by-step explanation:

2(4z-3-21)=166-46
Combine like terms
2(4z-24)= 120
Distribute
8z-48= 120
Add 48 to both sides
8z= 168
Divide both sides by 8
z=21
Final answer: z=21
