Answer:
The carpenter used 2 7/4 feet of plank for the shelf
Step-by-step explanation:
Total length of plank =10 1/2 foot
He used
For Deck board=4 1/4 feet
Step=3 2/3 feet
Shelf=x feet
Total plank=deck board + step + shelf
10 1/2 = 4 1/4 + 3 2/3 + x
Change the fractions
21/2 = 17/4 + 11/3 + x
Add 17/4 + 11/3
21/2 =51+44/12 + x
21/2= 95/12 + x
Collect like terms
21/2 - 95/12 =x
126-95/12 = x
31/12=x
2 7/12 =x
Therefore, the carpenter used 2 7/4 feet of plank for the shelf

Answer:
$30
Step-by-step explanation:
Let the price of sweatshirt be $x.
Discount percentage = 30%
Discount in dollars = 30% of $x
Discount in dollars = 30/100 of $x = $ 30x/100
Given that discount in $ is 9
thus
30x/100 = 9
x = 9*100/30 = 30
Thus, the original price is $30
