given 
= 
( cross- multiply )
10j = 54 ( divide both sides by 10 )
j = 
= 
← in simplest form
(9)
let h be the hours worked daily , then
3h = 20 
= 
( divide both sides by 3 )
h = ÷ 3
= × 
= 
= 6 
She worked 6 hours each day

Answer:
<h2>The cable measures 180 meters.</h2>
Step-by-step explanation:
To solve this problem, we need to find the Least Common Factor between 15 and 9.
15 9 | 3
5 3 | 3
5 1 | 5
1
So, the Least Common Factor would be 3x3x5 = 45. But, we need a multiple of this number which must be between 150 and 200. So,
45 x 4 = 180.
Therefore, the cable measures 180 meters.
Answer: 16.31 L
22.108 L - 5.80 L = 16.308 L
The reason that the answer is only precise up to 2 decimals is because our least precise measurement goes as far as 2 decimals and you can only be as precise as your least precise measurement
