Answer:
a
Step-by-step explanation:
they are right
60 days / 8 workers = 7.5
60 days - 12 days of work done = 48
48 x 7.5 = 360
360/ 12 workers = 30 days to finish rest of the house.
Step-by-step explanation:
10X+ 180= 500
10X= 500-180
10X= 320. .....divine both sides by 10 to solve for X
X = 32.
check
10(32)+180 = 500
320+180 =500
500 =500...confirmed
