To find the weight of 1 load of stone, divide 2/3 by 4.
To divide fractions, use keep change flip.
Keep the first fraction the same, change the division sign into a multiplication sign, and flip the second fraction.
I attached the work and answer for this problem. If you have any questions please feel free to ask.
Hope this helps.
Step-by-step explanation:
length of a rectangle = (3x+4)
breadth of a rectangle =(2x-1)
perimeter of a rectangle =?
we know that,
perimeter of a rectangle=2 (length+breadth)
2 (3x+4)+(2x-1)
(6x+8)+(4x-4)
(6x+4x)+(4+8)
10x+12
x=12-10=2
x=2#

Step-by-step explanation:
Answer:
4 units
Step-by-step explanation:
Create an equation where w is the width of the rectangle
Use the area formula, A = lw.
Since the length is the sum of the width and 1, it can be represented by w + 1
Plug in this and the area into the formula, and solve for w
A = lw
20 = (w + 1)(w)
20 = w² + w
w² + w - 20
(w + 5)(w - 4)
Solve for w:
w + 5 = 0
w = -5
w - 4 = 0
w = 4
Since the width cannot be negative, the answer must be 4.
So, the width of the rectangle is 4 units.
Answer: The other dimension can be expressed as
(50 - 2L)/2
Step-by-step explanation: First and foremost, we would let the other dimension be represented by B. Then, the perimeter of a rectangle is measured as L+L+B+B or better put;
Perimeter = 2L + 2B
Where L is the measurement of the longer side and B is the measurement of the shorter side.
In this case the perimeter of the rectangle measures 50m, and this can now be written as
50 = 2L + 2B
Subtract 2L from both sides of the equation
50 - 2L = 2L - 2L + 2B
50 -2L = 2B
Divide both sides of the equation by 2
(50 - 2L)/2 = B
