Answer:
280m
Step-by-step explanation:
Work rate would be (210m)/(45people)(60days)=7/90 m/(people)(day)
7/90 m/(people)(day) * 72people * 50days =280m
Since, the co-interior angles(55° and 125°) are supplementary(sum is 180), therefore the lines are parallel.
It will be 11v
If you rearrange it to 12v- v
Then it’ll look like 12v- 1v
Which equals 11v
Hey!
Let's write it,

Add

to both sides,


Subtract

from both sides.


Since we don't want a negative variable, we have to divide both sides by

.

Our answer would be,
