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:
m^1/15
Step-by-step explanation:
Answer:
67,200 (please note you did not specify the currency this is figured in so that is important to include in your answer. If this answer is in dollars, then make sure you add a dollars sign and specify "dollars" in your answer. If it is in another currency then put that in).
Step-by-step explanation:
First, we need to figure out how much the doctor makes per hour. Since there are 4, 15 minute billing periods per hour, we multiple to find the hourly billing charges:
4
(this is the amount the doctor makes per hour)
Next, we have to take that hourly charge and multiply it by 2 because we know the doctor works two hours per day:
(this is the amount the doctor makes per day working two hours)
Finally, we know the doctor attends to the clinic two hours per day and seven days per week. We have to multiply the amount of money earned in two hours (9600) by 7 days:
(this is the amount the doctor makes in seven days, billing two hours per day)
