Working 8 hours a days,15 people can do a piece of work in 12 days. Working 9 hours a day how many people will complete the same work in 16 days?By making table.​

Step-by-step explanation:

12 days × 8 hours/day = 96 hours

15 workers × 96 hours = 1,440 worker-hours

16 days × 9 hours/day = 144 hours

10 workers can finish the job in 16 days, working 9 hours a day.

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false
