How do you solve Linear Equations?
A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables." A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.
Calculation7x=21 is the intermediate state.
x=3 is the given solution
Substitue x in the given solutions and find y from the given solutions.
9+2y=7 and 6-y=7
so y=-1 in both the cases.

[tex]\sqrt[3]{100}[/tex] is in between [tex]\sqrt[3]{64} \\[/tex] and [tex]\sqrt[3]{125}[/tex] so that means that the answer is between 4 and 5 so the best answer is 4.5.
The original price of a skateboard, not including tax, was $96. Charlie bought the skateboard on sale, and he saved 30% off of the original price.
What was the sale price of the skateboard?
Answer:
$67.20
Step-by-step explanation:
"30% off" translates into multiplying the original price by 1.00 - 0.30, or 0.70.
0.70($96) = $67.20 is the sales price

I've been crying about this question plz Help i'll give brainliest. Question 7
Step-by-step Answer/Explanation(answers are underlined and bolded):
okay, first you want to identify all the numbers and what they mean:
lawyers:235 (within the main number of lawyers: Criminal lawyers: 74)
Family doctors: 87
Sergeons: 30
From there, add up all of said numbers (ignore the Criminal lawyers for now):
235 + 87 + 30 = 352
(352 is going to be the denominator or the number that we are going to be dividing from.)
Next, we start answering the questions!
the first one is asking for the percent of sergeons.
To do this, we need to take the number of sergeons listed, 30, and divide 352 from it:
30/352 = .0852
then multiply this by 100:
.0852 x 100= 8.52%
So the percent of sergeons is 8.52%
Next question: the percent of Family Doctors
so like the last question, we identify the number of doctors, 87, and divide 352 from it, then multiplying it by 100 after:
87/352 = .2472
.2472 x 100 = 24.72%
Meaning the percent of family doctors is 24.72%
Criminal Law is next:
repeat the steps in the last couple of problems:
72/352 = .2045
.2045 x 100 = 20.45%
Family Law:
Okay, so now, we need to take that 235 from earlier and subtract it from 72 (the criminal law students) to get the number of students going into family law.
235 - 72 = 163
now repeat the steps from the earlier problems:
163/352 = .3864
.3864 x 100 = 38.64%
(I don't particularly understand what the rest is asking...I figure you can probably figure out from here...? I hope this helps!!)
Based on historical data in Oxnard college, we believe that 37% of freshmen do not visit their counselors regularly. For this year, you would like to obtain a new sample to estimate the proportiton of freshmen who do not visit their counselors regularly. You would like to be 98% confident that your estimate is within 3.5% of the true population proportion. How large of a sample size is required
Answer:
A sample size of 1031 is required.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is of:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
37% of freshmen do not visit their counselors regularly.
This means that [tex]\pi = 0.37[/tex]
98% confidence level
So [tex]\alpha = 0.02[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.02}{2} = 0.99[/tex], so [tex]Z = 2.327[/tex].
You would like to be 98% confident that your estimate is within 3.5% of the true population proportion. How large of a sample size is required?
A sample size of n is required.
n is found when M = 0.035. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.035 = 2.327\sqrt{\frac{0.37*0.63}{n}}[/tex]
[tex]0.035\sqrt{n} = 2.327\sqrt{0.37*0.63}[/tex]
[tex]\sqrt{n} = \frac{2.327\sqrt{0.37*0.63}}{0.035}[/tex]
[tex](\sqrt{n})^2 = (\frac{2.327\sqrt{0.37*0.63}}{0.035})^2[/tex]
[tex]n = 1030.4[/tex]
Rounding up:
A sample size of 1031 is required.
When do you use a solid line for graphing a linear inequality?
Answer: You use it to represent that the equation your graphing is either greater than or equal too or less than or equal too
Step-by-step explanation:
A dotted line is there to represent that the equation your graphing is either grater than or less than
So the solid line represents the same thing, except that they both have a possibility of being equal too which is why the line is solid.

Answer:
1st option (c = 15.00 + 3.50n)
Step-by-step explanation:
Answer:
A. c=15.00+3.50n
Step-by-step explanation:
We can find how much a single charm costs by taking the 2nd term and subtracting it by the first.
22.00-18.50=3.50
A charm is $3.50.
We can also find the initial price of the bracelet by taking the first term and subtracting off one charm.
18.50-3.50=15.00
The bracelet by itself is $15.00
Knowing n goes up by a rate of 3.50 and the initial price is 15.00, we can find the answer is
A. c=15.00+3.50n

A new road was built to reroute traffic around the park, as shown in the diagram below. About how many extra miles will the traffic travel?
9514 1404 393
Answer:
A. 20 miles
Step-by-step explanation:
You will recognize this right triangle as a 3-4-5 right triangle scaled by a factor of 10 miles. That means the "old road" length is 50 miles. The new road lenth is 40+30 = 70 miles, so the added distance is ...
70 miles - 50 miles = 20 miles . . . . extra travel distance
__
Maybe you've never heard of a 3-4-5 right triangle, so you need to use the Pythagorean theorem to compute the length of the old road. It tells you the square of that length is the sum of the squares of the new road segment:
OR² = 40² + 30²
OR² = 1600 +900 = 2500
OR = √2500 = 50 . . . . the length of the old road is 50 miles

=======================================================
Explanation:
Start in the first row. The stem here is 4, which forms the tens digit of the value. The first leaf of this row is 3, so it's the units digit.
A tens digit of 4 and units digit of 3 forms the value 43. The value 43 is the smallest value of this data set. We call this the minimum.
The max is 93 for similar reasons, but we look at the opposite endpoint of the spectrum. Locate the bottom row (stem = 9) and note the last leaf here is 3. So that's how we get 93 here.
Now compute the range:
range = max - min
range = 93 - 43
range = 50, answer is choice C
The May 1, 2009, issue of a certain publication reported the following home sale amounts for a sample of homes in Alameda, CA that were sold the previous month (1,000s of $). 591 820 575 607 349 1,288 412 543 557 676 A button hyperlink to the SALT program that reads: Use SALT. (a) Calculate and interpret the sample mean and median. The sample mean is x
The sample mean is $641.80 thousand and the sample median is $583 thousand.
This means that the average sale price for a home in this sample was $641.80 thousand and that half the sales were for less than the median price and price and half the sales were more than the median price.
Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number
Mean = sum of the numbers / total number
sum of the numbers = $ (591 + 820 + 575 + 607 + 349 + 1,288 + 412 + 543 + 557+ 676) = 6418
total number = 10
Mean = $6418 / 10 = $641.80
= $641.80 thousand
Median can be described as the number that occurs in the middle of a set of numbers that are arranged either in ascending or descending order
Arranging the prices in ascending order : 349, 412, 543, 557, 575, 591, 607, 676, 820, 1288
The two numbers in the middle of the set of numbers are 575 and 591
Median = (575 + 591) / 2 = $583
$583 thousand
