The solutions of the equations for x are given as follows:
a. x = 36.
b. x = 15.
<h3>What is the solution for item a?</h3>
The equation for item a is given by:
x/3 - 5 = 7
Isolating x, we have that:
x/3 = 12
x = 3 x 12
x = 36.
<h3>What is the solution for item b?</h3>
The equation for item b is given by:
x/2 - 5 = 2.5
Isolating x, we have that:
x/2 = 7.5
x = 7.5 x 2
x = 15.
Hence the solutions are:
a. x = 36.
b. x = 15.

Answer:
$X = $12y
Step-by-step explanation:
In this question, we are asked to give an expression to represent the amount of money charged to a man who stayed in a motel for a particular number of days.
Firstly, we need to know the amount of money charged per day. This is visible from
the question and it is equal to $y.
Secondly, the number of days/night stayed is 12 days. This means that the amount of money he was charged is 12 * y = $12y
Since the amount of money charged is equal to $x, the amount to pay can be expressed in terms of y and x to be
$X = $12y
The 99 percent confidence interval for the true mean length of the bolt is CI = (2.8712, 3.1288)
<h3>How to find the confidence interval?</h3>
Confidence Interval is used to tell us the degree of certainty or uncertainty that is existent in a sampling method.
The general formula for confidence interval is;
CI = x' ± z(s/√n)
where;
x' is sample mean
z is z-score at confidence level
s is sample standard deviation
n is sample size
We are given;
sample size; n = 36
Sample mean; x' = 3 inches
standard deviation; s = 0.3 inches
confidence level = 99%
z at 99% CL = 2.576
Thus;
CI = 3 ± 2.576(0.3/√36)
CI = 3 ± 0.1288
CI = (2.8712, 3.1288)
