Answer:
Step-by-step explanation:
Let the number of hours Nick does the job alone to be x - 3 hours
Hence, in 1 hour, Nick has done 1/x - 3
Together they complete the job in 9 hours
Hence, let's represent the job as 1
9/x + 9/x - 3 = 1
Multiply through by (x)(x-3)
9(x- 3) + 9(x) = 1
9x - 27 + 9x = (x)(x-3)
-27 = x² - 3x
x² - 3x +27 = 0
Answer:
5 31/30 or 181/30
Step-by-step explanation:
Answer:
(a) 11.
(b) 5.
Step-by-step explanation:
(a)√124:
11*11 = 121 so an estimate is 11.
(b) ∛124
5*5*5 = 125
So an estimate is 5.
125-45=M would be a simple way of writing the amount taken from the original
Answer:
The definition of adjacent in math can mean a couple of different things. For angles, adjacent angles would be any two angles that share a side. In other words, two angles right next to each other.
A more broad meaning is just any two geometric shapes that are next to each other in a figure.
