This question is incomplete, the complete question is;

Nine pieces of 8-in. × 12-in. duct that is 2 $\frac{2}{3}$ ft in length is needed for a building. What is the total length (in ft) needed?

Answer:

the total length needed is 24 ft

Step-by-step explanation:

Given the data in the question;

the length of one piece of 8-in. × 12-in. duct is 2 $\frac{2}{3}$ ft

Now to find the total length for nine pieces of the duct;

we simple multiply 2 $\frac{2}{3}$ ft by nine

Total length = 9 × 2 $\frac{2}{3}$

we convert the mixed fraction to improper fraction

2 $\frac{2}{3}$ = 8/3

Total length = 9 × (8/3) ft

Total length = 24 ft

Therefore, the total length needed is 24 ft

Answer:

x = 31.2

Step-by-step explanation:

$\frac{1}{2}$ x - 19.7 = -4.1

$\frac{1}{2}$ x = 15.6 --- add 19.7 to both sides to get rid of -19.7

x = 31.2 --- multiply both sides by 2 to get rid of $\frac{1}{2}$
