Fill the array using doubling and halving
Question is incomplete, as the array is not given.
However, the solution is as follows:
Double 25 and half 68
Double 50 and half 34
The above is now easy to solve
It is 9. You have to add 33y, then divide by 11 and you get x = 3y + 9
Answer:
2l + 2w = 96 ..... eqn1
lw = 504 ...... eqn2
Step-by-step explanation:
To model this case where we have two unknowns l and w, we need two equations.
Firstly, the perimeter of a rectangle is given by
2l + 2w = p
Where l,w and p are length, width and perimeter of the rectangle respectively.
Hence,
2l + 2w = 96 ... eqn1
Secondly, the area of a rectangle is given by
Length × width = Area
Hence,
l × w = 504
lw = 504 ... eqn2
With these two equations the solutions to the length and width of the rectangular pool can be derived.
Answer:
1.65
Step-by-step explanation:
He pays 5 dollars for the magizine which is valued at 3.35 and receives 1.65
Answer: Divide the total displacement by the total time.
In order to find the velocity of the moving object, you will need to divide the change in position by the change in time. Specify the direction moved, and you have the average velocity. Example 1 (cont.): The car changed its position by 36 meters over 8 seconds.
