orkers joined the crew. together they completed the remaining job in 2 days. how many new workers joined the crew?
1 answer:
Answer:
12 people
Step-by-step explanation:
On the morning of the 3rd day, there are 4 working days (of the 6 days) left for 12-person crew, or 4*12 = 48 man.days
The team completed the remaining job in 2 days. This means 48 / 2 = 24 people helped complete the task.
So the number of new workers who joined the crew is
24 - 12 = 12 people

Answer: 250 hamburgers
Step-by-step explanation: x= hamburgers
If there are 72 more cheeseburgers than hamburgers there are:
x+72
The number of cheeseburgers and hamburgers=572 so:
572= x+72+x
Then solve
572=x+72+x
572=2x+72
-72 -72
———————
500=2x
500/2=2x/2
250=x
Earlier snow depth = 2 feet
later snow depth = 1.6 feet
change
2 - 1.6
0.4 feet
percentage change
(0.4 / 2) * 100
20 %
y-y1 = m(x-x1)
y-1 = 4/5 (x+2)
y-1 = 4/5x +14/5
y = 4/5x +9/5
