The value of d is 12 of the given equation.
What is the equation?
The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
What are Arithmetic operations?
Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
* Multiplication operation: Multiplies values on either side of the operator
For example 12×2 = 24
Given that the equation as:
⇒ 1/8 (3d - 2) = 1/4 (d + 5)
Open the parentheses and apply the multiplication property
⇒ 1/8 × 3d - 1/8 × 2 = 1/4 × d + 1/4 × 5
⇒ (3/8)d - 1/4 = (1/4)d + 5/4
Rearrange the terms of likewise and apply the arithmetic operations,
⇒ (3/8)d - (1/4)d = 1/4 + 5/4
Multiply by 8 both sides of the equation,
⇒ 3d - 2d = 2 + 10
⇒ d = 12
Therefore, the value of d is 12 of the given equation.

8(1/8(3d-2)=1/4(d+5))
The equation then turns into this because the 8 and 4 cancelled out with the 8.
1(3d-2)=2(d+5)
Now, we need to distribute the left over numbers into the parenthesis.
3d-2=2d+10
And finally, we need to get the d's on one side, and the numbers on the other, so we subtract 2d from both sides and add the 2 to both sides. They then cancel out to make
d=12

Answer:
D
Step-by-step explanation:
We need the formula for arc length (in radians) to solve this problem. The formula is:
Where
s is the arc length
r is the radius of the circle
is the intercepted angle
In this diagram, we can see that is beign intercepted by the big arc with measure 20 cm. So arc length, s, is 20
Also, if we look, we see that the radius is 5 cm, so r = 5
Now, we substitute into formula and find :
This is given in radians, so is 4 radians
D is the correct answer choice.
1. a=c
2.
3. b-a=c-b
4. a
5. if a=b, then b=c

b : c
Imagine if the ratio is as follows :
3 : 6
6 : 12
Yes, only number 2 is correct.
Your number 4 seems to only consist of a. Hence, I can't make any assumptions based on that.
So yes, only number 2 is correct.

Shallowest part of the swimming pool = 3 feet deep
Thus the ratio of both swimming pool depth is:
=> 12 : 3
12 – 3 = 9
The deepest part of swimming pool is 9 feet deeper compare to the shallowestpart of the swimming pool.
Ratio is simply mean the number of x is to the number of y
=> x : y
