Answer:
x = -4
Step-by-step explanation:
logs (8 - 3x) = log20
Since we are taking the log on each side
log a = log b then a = b
8 -3x = 20
Subtract 8 from each side
8 -3x-8 =20 -8
-3x = 12
Divide by -3
-3x/-3 = 12/-3
x = -4
So you start with 23
for every row up you have -3
equation is
# of boxes= 23- 3x
x representing the number of rows above the bottom
# of boxes= 23- 3x=
23-3(5)= 8
5 for the top row
bottom row has 23
1 row above 23-3(x)=20
2 row above 23-3(x)= 17
3....23-3(x)= 14
4....23-3(x)=11
5...23-3(x)= 8
therefore just add all boxes each row has
23+20+17+14+11+8= 83
I hope this helps

Step-by-step explanation:
Answer: The tailor made 8 complete hats
Step-by-step explanation:
Amount of fabrics available to make hat = 6 2/3 yards
1 hat requires = 5/6 yards
Number of hat to obtain from the available fabric = Amount of fabrics available to make hat / requirement of 1 hat
=(6 2/3) / (5/6)
(20/3) / (5/6)
20/3 x 6/5 = cancelling out, we are left with
4x2= 8 hats
or
(20/3) / (5/6)
6.6666 /0.83333
= 8.00002= 8 hats
