To find the correct answer, you have to simplify the equation.
Multiply -1/2 by everything in the parenthesis.
3/4x - 3x - 1/2 - 3x. Combine like terms.
-21/4x - 1/2. Turn -21/4x into a mixed number.
-5 1/4x - 1/2.
Your answer is D
Answer:
C. 125 : 1
Step-by-step explanation:
V(A) : V(B) = [r(a)]³ : [r(b)]³ = 15³ : 3³ = (5*3)³: 3³ = (5³*3³) : 3³ = 5³ : 1 = 125:1
First step is breaking down the word problem.
I think of a number.
U don’t know the number so called it x
The number add 3.
X + 3
Then it says multiply the outcome by 7
You are not sure what what the outcome could be so you put it in brackets
(X+3) times it by 7
(X+3) 7
The solution is 24.5
Solution means equal
(X+3) 7 = 24.5
Now you have the equation
To solve for x
By the BOMDAS method
You times 7 by what is inside the brackets
7x + 21 = 24.5
Now transpose
7x = 24.5 - 21
7x = 3.5
Divide both sides by 7
7x/7 = 3.5/7
Which cancel out 7 and leave x
So the original number is
Or u could say x = 0.5
