So let's take a look at the answers they give. A is 2.5 - 2.2 and all that is is switching the numbers so that isn't right. B they do addition instead of subtraction so that can't be right. C they do 2.2 + (-2.5) and when you add a negative number it's like subtraction because a negative number is under 0 and so your adding a number under 0 so you go down. So the answer is C.
If you need me to explain it different let me know. Hope this helps!
The origional expression would equate to -0.3
The reason A is incorrect is that you can not change the order of subtraction. This answer equates to 0.3.
The reason B is incorrect is that adding is not the same as subtracting. This answer equates to 4.7.
The reason D is incorrect is that subtracting a negative is the same as adding. This would equate to 4.7
The reason C is correct is that adding negative is the same as subtracting. This would equate to -0.3.

Final answer:
To find the equation of a line that is perpendicular to 5x-3y=12 and passes through (3,1), we first identify the slope of the given line, find the negative reciprocal to determine the perpendicular slope, and then use the point-slope form to derive the equation, resulting in y = -3/5x + 14/5.
Explanation:
The question asks us to write the equation of a line that is perpendicular to the given line 5x-3y=12 and passes through the point (3,1). Perpendicular lines have slopes that are negative reciprocals of each other. First, we find the slope of the given line by rearranging it into slope-intercept form:
5x - 3y = 12
-3y = -5x + 12
[tex]y = \(\frac{5}{3}x - 4\)[/tex]
This reveals the slope of the given line is [tex]\(\frac{5}{3}\).[/tex] The slope of the line perpendicular to it would therefore be [tex]\(-\frac{3}{5}\)[/tex]since [tex]\(-\frac{3}{5}\)[/tex]is the negative reciprocal of [tex]\(\frac{5}{3}\).[/tex] Next, we use the point-slope form for the equation of a line with the known point (3,1):
y - y1 = m(x - x1)
[tex]y - 1 = \(-\frac{3}{5}\)(x - 3)[/tex]
Multiplying out, we get:
[tex]y - 1 = \(-\frac{3}{5}\)x + \(\frac{9}{5}\)[/tex]
Finally, adding 1 to both sides to solve for y:
[tex]y = \(-\frac{3}{5}\)x + \(\frac{9}{5}\) + 1[/tex]
[tex]y = \(-\frac{3}{5}\)x + \(\frac{14}{5}\)[/tex]
This is the equation of the line that is perpendicular to 5x-3y=12 and passes through (3,1).

Answers
(14x+4)+(16x-4)=180
After you solve for x, you should look to solve for y. How can we figure out what y is? If you're familiar with the vertical angle theorem, you'll know that all vertical angles (angles that are directly across from each other diagonally) are equal. So we know that 14x+4=4y-8. You can use the value of x you solved for before to solve this one fairly easily, and then you'll have both values.

what is the price of a remote control helicopter is $34.40. A remote control boat cost 4/5 the price of the helicopter. Sales tax on the remote control boat is 8%. What is the price of the remote control boat, including sales tax? Round your answer to the nearest penny
Answers
34.4 x 0.01 = 0.344
Then, let’s multiply that 1% by 80 to get the price of the remote controlled boat, since it’s 4/5 the price of the helicopter.
0.344 x 80 = 27.52
$27.52 is the regular price of the boat.
Now, let’s find the 8% of that price. We’ll first first 1% and then multiply our answer by 8 to get 8%.
27.52 x 0.01 = 0.2752
0.2752 x 8 = 2.2016
Sales tax will be $2.20
The total will add the sales tax to the regular total of the boat.
$27.52 + $2.20 = $29.72
$29.72 is your answer.

Ned has scored 84 points in the first 6 games of the basketball season. How many points per game has Ned scored?
Answers
84 points : 6 games = 14 points : 1 game
SCALE FACTOR: To figure out the scale factor divide the information that is matched. In this case it would be 6 games divided by 1 game. Your scale factor is 6. Multiply the information that matches the information that is missing. So, in this case it would be 84 points divided by 6. You are dividing because you want to know how much Ned scored in one game, now if you wanted to know how much Ned made in 12 games you would multiply 84 by 6. 84 divided by 6 = 14

To one decimal point, how many millimeters are there in 57 inches?
Answers
There are 1447.8 millimeters in 57 inches. which is determined by multiplying 57 by 25.4.
How to convert Inches to millimeters?The methodology to convert inches to mm is relatively simple. To convert inches to millimeters, you must multiply the unit by 25.4.
For example, if you have to convert 5 inches to millimeters, you need to multiply 5 by 25.4.
Therefore, 5 inches = 5 × 25.4 = 127 millimeters
We determine the number of millimeters there in 57 inches.
We have to convert 57 inches to millimeters,
We need to multiply 57 by 25.4.
So, 5 inches = 57 × 25.4 = 1447.8 millimeters
Therefore, there are 1447.8 millimeters in 57 inches.

Amy is in a craft store looking at packages of Pom-poms. Amy sees packages of four red pom-poms. Amy says she can buy seven packages of four pom-poms or four packages of seven pom-poms because she will get the same total of pom-poms. Is Amy correct? Show all mathematical thinking.
Answers
Multiply each number to get the value.
7 x 4 = 28
Shell get 28 pom poms.
Now let's calculate the number of pom pom if she gets 4 packages of 7.
4 x 7 = 28
She gets 28 pom poms.
Therefore, both of these options gets the same amount of pom poms, which is 28, therefore Amy is correct.
Amy is incorrect because both options will give her the same total number of pom-poms.
Explanation:Amy is incorrect in her statement. Let's calculate the total number of pom-poms in each scenario. If she buys 7 packages of 4 pom-poms, she would have 7 * 4 = 28 pom-poms. On the other hand, if she buys 4 packages of 7 pom-poms, she would have 4 * 7 = 28 pom-poms as well. So, both options result in the same total number of pom-poms.

Police set up an auto checkpoint at which drivers are stopped and their cars inspected for safety problems. They find that 14 of the 134 cars stopped have at least one safety violation. They want to estimate the percentage of all cars that may be unsafe.
Answers
To estimate the percentage of all cars that may be unsafe, divide the number of cars with safety violations by the total number of cars stopped, and then multiply by 100. Based on the data from the auto checkpoint, approximately 10.45% of all cars may be unsafe.
Explanation:To estimate the percentage of all cars that may be unsafe, we can use the proportion of cars with safety violations found at the auto checkpoint. We can calculate the percentage by dividing the number of cars with safety violations by the total number of cars stopped, and then multiplying by 100.
In this case, 14 of the 134 cars stopped had safety violations. So, the percentage of cars that may be unsafe is (14/134) x 100 = 10.45% (rounded to two decimal places).
Therefore, we can estimate that approximately 10.45% of all cars may be unsafe based on the data from the auto checkpoint.
