Answer:
The value of x when f(x) equals 6 is 3/5.
Step-by-step explanation:
In order to solve this problem, we shall start by inputting what we know.
Since the problem provides you with the value of f(x), we will input the value in the given equation.
Original Equation: f(x) = 5x + 3
New Equation: 6 = 5x + 3
Now that all known values of variables have been added to the equation, we will begin to solve.
Start by subtracting both sides of the equation by 3. This step is necessary to isolate x in order to find it's value.
6 = 5x + 3
6 - 3 = 5x + 3 - 3
3 = 5x
Next, we shall divide both side of the equation by 5. This step will allow us to isolate x and finally solve its value.
3 = 5x
3/5 = 5x/5
3/5 = x
Thus, the value of x in f(x) = 5x + 3 is 3/5.
---
To be sure your answer is correct, insert the values of both f(x) and x into the equation provided and solve like so...
f(x) = 5x + 3
6 = 5(3/5) + 3
6 = 3 + 3
6 = 6 ✅

Answer:
The answer to your question is 0.83 or 83%
Step-by-step explanation:
Data
5 red marbles
10 blue marbles
14 yellow marbles
Process
1.- Calculate the total amount of marbles
Total amount = 5 red + 10 blue + 14 yellow
Total amount = 29 marbles
2.- Calculate the amount of marbles that are not red
No red marbles = 10 + 14
= 24 marbles
3.- Calculate the probability
Probability of not pulling a red marble = 
Probability of not pulling a red marble = 
Answer:
The value of x = -13
Step-by-step explanation:
Given the expression

Multiply both sides by 2

simplify

Subtract 1 from both sides

Simplify

Divide both sides by 0.2

Simplify

Therefore, the value of x = -13
