Triangles are in total 180 degrees. The two triangles are basically 1 triangle split in half. If the triangle share the same side, has similar angles (shown by the curves on both sides at the top(Angle BAC and CAB), and has similar sides(shown by the hashes made in the lines AC & AB), you can conclude 'x' as a 90 degree angle.
To find y:
The measurment of the angle DCA is 47 degrees. For x, we concluded the answer to be 90 degrees, making the other side of the line 90 degrees as well.Since a triangle is 180 degrees, we can add 47 and 90 to get 137. Taking that answer, we subtract it from the value of 180 degrees to get 43 degrees. So y equals 43.
solve the system of equation-5x+2y=9 y=7x
Answers
y = 5x/2 + 9/2
(I don't know if this is correct)
Hope this helps!
The system of equations -5x + 2y = 9 and y = 7x is solved using substitution, yielding the solution x = 1 and y = 7.
To solve the system of equations -5x + 2y = 9 and y = 7x, we can use substitution since the second equation gives us 'y' in terms of 'x' directly. We substitute 7x in for y in the first equation:
-5x + 2(7x) = 9
-5x + 14x = 9
9x = 9
x = 1
Now that we have the value for x, we can find y using the second equation:
y = 7(1)
y = 7
Therefore, the solution to the system of equations is x = 1 and y = 7.

Your answer is true
True, 50 tens times 4 hundreds equals 40 tens times 5 hundreds.
50 tens times 4 hundreds will equals 40 tens times 5 hundreds reason been if you multiply 50 by 4 hundred it will give us 20,000 and if you multiply 40 tens by 5 hundreds it will still give us 20,000.
Hence:

how do you solve this 200 are in a race 20 drop out 16 take a break 40 were added how many people areni the race now
Answers
The 16 isn’t in the equation because they are coming back.
So your answer is 220.
You have 200 people in a race, and 20 drop out. Meaning, you must subtract:
200 - 20 = 180
Next, 16 take a break, so you must subtract again:
180 - 16 = 164
Finally, 40 people are added back, so, you must add:
164 + 40 = 204
And that's how you will get your answer! ^

Answer:
The result of the subtraction is [tex]\(57\).[/tex]
Explanation:
To subtract the numbers given, we need to add all the positive numbers and then subtract the sum of the negative numbers.
Positive numbers: [tex]\(6 + 4 + 6 + 4 + 5 + 5 + 6 = 36\)[/tex]
Negative numbers: [tex]\(-6 - 6 - 4 - 1 - 4 = -21\)[/tex]
Subtracting the sum of the negative numbers from the sum of the positive numbers:
[tex]\(36 - (-21) = 36 + 21 = 57\)[/tex]
So, the result of the subtraction is [tex]\(57\).[/tex]

Solve using distributive property 6 x 4.4
Answers
Final answer:
To solve the equation 6 x 4.4 with the distributive property, multiply 6 by each part of 4.4 (which is divided into 4 and 0.4) separately and then add the results together. This yields 24 + 2.4, which equals 26.4.
Explanation:
To solve the multiplication problem 6 x 4.4 using the distributive property, we can break down the number 4.4 into 4 and 0.4. Then we distribute the multiplication over these two addends separately.
This can be written as:
6 x (4 + 0.4) = (6 x 4) + (6 x 0.4)
Next, we solve each part of the equation:
6 x 4 = 24
6 x 0.4 = 2.4
Finally, we combine these two results to get the final answer:
24 + 2.4 = 26.4
Thus, 6 multiplied by 4.4 equals 26.4.

Unit 4 Review & Sample Work Inequalities Solving and Graphing Inequalities Graph the solution sets to the inequalities on the number lines below.
https://gyazo.com/00a920c17b5ad39849d47d70484cca0c
Answers
Graphing the solution sets to inequalities involves using open or closed circles to represent non-inclusive or inclusive endpoints and shading the number line to indicate the direction of the inequality.
Explanation:To graph the solution sets to the inequalities on number lines, we need to understand and apply the concepts of inequalities and number line graphing. If an inequality has a 'less than' (<) or a 'greater than' (>) symbol, we use an open circle on the number line to indicate that the endpoint is not included in the solution. Conversely, if an inequality includes 'less than or equal to' (\u2264) or 'greater than or equal to' (\u2265), we use a closed circle to show that the endpoint is part of the solution set. The inequality symbol will also determine the direction in which we shade the number line: to the left for 'less than' and to the right for 'greater than'.
For example, if we have an inequality x > 3, we place an open circle at 3 and shade the number line to the right of 3, indicating all numbers greater than 3 are included in the solution set. If the inequality is x \u2265 5, we place a closed circle at 5 and shade to the right, including 5 and all numbers greater than it. Similarly, with x < -2, an open circle would be placed at -2 and the line shaded to the left. Lastly, for x \u2264 -4, a closed circle at -4 with the line shaded to the left indicates the solution set.

_________________________________
Explanation:
_________________________________
Choice [A]: "whole number only" ; is incorrect; since any decimal value/ decimal-containing value — including this given value: "8.2" — is not a "whole number" ; and NOT an integer.
Thus, we can eliminate Choices: [D]: and [B] ; and we are left with:
"Choice: [C]: "Rational numbers only".
Note: "8.2" is a rational number; since the number is real; and since the number is not "irrational". An "irrational number" would mean that the resulting decimal form would be "non-terminating" AND "non-repeating".

Choice: [B]: is: "integers and rational numbers". Yes; "5" is both an "integer"; AND a "rational number"; and there is no word, such as "only" in this answer choice. So, this answer could be correct; and arguably is a better answer than "Choice: [A]" .
→ So; at this point, let us "tentatively eliminate": "Answer choice: [A] " .
_________________________________
Choice: [C]: is: "rational numbers only". Note that: "5" ; is, in fact, a "rational number"; however, take note of the word: "only"; (as mentioned in: "Answer choice: [A]" .
→ At this point, "Answer choice: [B]: is arguably a better answer than choices: [A} & [C].
→ So; we can tentatively eliminate choices: [A] & [C].
_________________________________
Choice [D]: is: "integers, whole numbers, and rational numbers" .

We are left with: "Choices: [B] and [C] " .

The problem deals with the segment addition postulate. By setting up and solving the relevant equation (2x + 7 = 6x - 5), we find that x = 3. Therefore, the length of AB = 6.
Explanation:The subject of this question is segment addition postulate in mathematics. Given that B is between A and C, it implies that AB + BC = AC. From the problem, it's given that AB = 2x, AC = 6x - 5 and BC = 7. Setting up the equation would yield 2x + 7 = 6x - 5. Solving this equation gives us x = 3. Therefore, by substituting x=3 in AB = 2x we find that AB = 6.

A common mistake made on problems like these is to say the answer is 1/12.
The only roll that really matters in this problem is the second one. This is because the first role only determines what the second role must be. Therefore, you only take the probability of rolling one fixed number in one roll, which would be one in six.

Answers
Percent: 6% = 0.06
Now we will multiply the cost of the house by the percentage to find the commission amount:
