This doesn’t make any sense
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
The correct answer is: -2x - 5y + 7z=?
The main formula is integr U^p du = (1/1+p)U^p+1
let be U=<span>(25 - 16x^2)^-1/2,
</span>1/sqrt(25 - 16x^2) = (25 - 16x^2)^-1/2
du= -1/2)(-32x)(25 - 16x^2)^-1/2dx
integ du/-1/2)(-32x)= integ(25 - 16x^2)^-1/2dx
nteg du/16x)=1/16xu+c=integ(25 - 16x^2)^-1/2dx
finally
integ 1 / sqrt(25 - 16x^2) dx = 1/16xu+c= (1/16x)(<span>(25 - 16x^2)^-1/2) +c
</span>
Answer:
x=7
Step-by-step explanation:
10+4x=5(x-6)+33
10+4x=5x-30+33
10+4x=5x+3
10=5x-4x+3
10=x+3
x=10-3
x=7
