7n - 2p
The value of the unknown variable "x" given that -6x + 3= 45 is -7
Equations are expressions separated by an equal sign. They can contain one or more variables.
The equation given in question is a linear equation containing one unknown variable "x".
The equation is expressed as -6x + 3 = 45
To get the value of x, we will follow the steps below:
Step 1: Subtract 3 from both sides of the equation
-6x + 3 - 3 = 45 - 3
-6x = 42
Step 2: Divide both sides of the expression by -6
-6x/-6 =42/-6
x = -7
This shows that the value of the unknown variable "x" is -7.

Answer:
It should take 3.43 days for the two of them to paint the house if they work together.
Step-by-step explanation:
The together rate is the sum of each separate rate.
In this problem:
Together rate: 1/x
Adam's rate: 1/8
Judy's rate: 1/6.
So
Together rate = Adam's rate + Judy's rate
It should take 3.43 days for the two of them to paint the house if they work together.
In a symmetric distribution, better known as the Gaussian or normal distribution, two thirds of the observations or 66.67% of the observation belongs to the area between the -3∅ to +3∅ where ∅ is the standard deviation of the group. it is assumed here that the mean is 1 and the area under the curve is also 1.
