Given :-
- 12 workers can do a piece of work in 20 days .
To Find :-
- How many workers should be added to complete the work in 16 days ?
Solution :-
According to the question ,
→ In 20days 12 workers can do a piece of work.
→ In 1day 12*20 workers can do that work
( Less days , more workers )
→ In 16 days 12*20/16 = 15 workers can do the work.
So 15 -12 = 3 workers should be added to complete the work.
<u>Hence</u><u> the</u><u> required</u><u> answer</u><u> is</u><u> </u><u>3 </u><u>.</u>

The graph of a proportional relationship passes through the origin, and as a constant slope
The given parameter is:
- Proportionality constant (k) = 10/7
<h3>Condition for a proportional relationship</h3>
For a proportional relationship, the equation of the graph is represented as:
Substitute 10/7 for k

Answer:
twice
Step-by-step explanation:
y = - 1 is a horizontal line parallel to the x- axis and passing through all points with a y- coordinate of - 1
Drawing this line on the graph, from (0, - 1 ) we can see that it will intersect the graph at 2 places between (0, 0 ) and (2, - 2 ) and between (2, - 2 ) and (4, 0 )
Multiply 18 * 3 and 20 * 3
18*3 = 54
20 * 3 = 60
Length = 54 cm ; Width = 60 cm
Area = L x W
54 * 60 = 3240
Area = 3240 cm
