Answer:
225 = 266 - D
Step-by-step explanation:
the equation is written as the sentence is expressed
is means equal and minus is subtract
225 = 266 - D
Answer:
There are no solutions.
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4x/5+2/3+1x/5=x
4/5x+2/3+1/5x=x
(4/5x+1/5x)+(2/3)=x(Combine Like Terms)
x+23=x
x+23=x
Step 2: Subtract x from both sides.
x+2/3−x=x−x
2/3=0
Step 3: Subtract 2/3 from both sides.
2/3−2/3=0−2/3
0=−2/3
Answer:
There are no solutions.
Answer:
n and (n - 1) are consecutive integers.
Step-by-step explanation:
We are given 'n', a positive integer.
This 'n' can either be odd or even.
Case I:
When 'n' is odd
The n - 1 is even.
Note that the product of odd and even is always even. That is the product of n and (n - 1) is even.
Case II:
when 'n' is even
Then n - 1 is odd.
Again, using the similar logic we can say that the product of n and n - 1 should be even because here, 'n - 1' is even and 'n' is odd.
Answer:
21 ft by 66 ft
Step-by-step explanation:
From the question,
P = 2(L+W)............... Equation 1
Where P = Perimeter of the playing Field, L = Length of the playing Field, W = width of the playing Field.
If the Length of the Field is 45 ft longer than the width,
L = 45+W............ Equation 2
Substitute Equation 2 into equation 1
P = 2(45+W+W)
P = 90+4W............. Equation 3
Given: P = 174 ft.
Substitute into equation 3
174 = 90+4W
4W = 174-90
4W = 84
W = 84/4
W = 21 ft.
Substituting the value of W into equation 2
L = 45+21
L = 66 ft.
Hence the dimensions of the playing field is 21 ft by 66 ft
