x21
Step-by-step explanation:
(-2/3)x+13≥ -1

x-14*(-3/2) (I divided by -2/3 on both sides)
x21
51 minutes---------------------7 people------------------7 walls
x---------------------------------15 people-----------------15 walls

51 minutes * 7 people=x*15 people.
number of walls paint and minutes are directly proportional magnitudes.
51 minutes*15 walls=x * 7 walls.
therefore:
51 minutes*7 peoples*15 walls=x*15 people*7 walls
x=(<span>51 minutes*7 peoples*15 walls) / (15 people*7 walls)=51 minutes.
answer : 51 minutes. </span>
