If consider the Pythagorean Theorem and its converse. A, C, D, and E are correct statements.
What is Pythagoras's theorem?Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.
In this case, statement A is correct because 6, 8, and 10 are possible side lengths for a right triangle.
Statement B is incorrect because 10, 15, and 20 are not possible side lengths for a right triangle.
Statement C is correct because the Pythagorean Theorem works only for sides of a right triangle.
Statement D is correct because if the sides of a right triangle are of lengths 8 and 15, its hypotenuse is 17.
Statement E is correct because the converse of the Pythagorean Theorem allows us to calculate the side lengths of right triangles.
Thus, the correct statements would be options A, C, D, and E.

A used book store also started selling used CDs and DVDs. In the first week, the store sold 40 used CDs and DVDs, at
$6.00 per CD and $4.00 per DVD. The sales for both CDs and DVDs totaled $180.00. Write a system of equations to
represent this situation
Answer:
6c + 4d = 180
c + d = 40
c represents the CDs and d represents the DVDs.

The slope is -1/2 and the y intercept is 1
Step-by-step explanation:
Please explain how to solve this and the answer
Looking at the letter arrangement in the problem B is similar to W
Set those equal to each other and solve.
X + 24 = 2x -2
Subtract x from both sides:
24 = x -2
Add 2 to both sides:
X = 26
Now replace x in the equation for B
2x -2 = 2(26)-2 = 52-2 = 50
B = 50 degrees
The 3rd choice is the answer.

Hometown Gym charges a $200 membership fee and $45 per month. Local Gym charges a $50 membership fee and $55 per month. Write an equation to represent the situation. After how many months will the total amount of money paid to both gyms be the same?
Answer:
=> membership fee = $50
=> monthly fee = $55
=> First month = 105$
=> 50 + 55(x)
=> 50 + 55 (15)
=> 50 + 825
=> 875
Workout gym
=> membership fee = $200
=> monthly fee = $45
=> First month = 245$
=> 200 + 45(x)
=> 200 + 45(15)
=> 200 + 675
=> 875

Answer:
Variable x in first equationStep-by-step explanation:
Given system
x = 5y - 1x + 2y = 13Variables in this system are x and y.
Isolating a variable means rearranging the equation so that a variable of our interest is on its own in one side of the equal sign.
We see variable x is isolated in the first equation.
In the second equation both of the variables are on the same side so they are not isolated.
Answer:
x
Step-by-step explanation:
x=5y-1--(1)The x variable is isolated here as it's solo on left side
Solve the equations
x+2y=13x=-2y+13--(2)Equate
5y-1=-2y+137y=14y=2x=10-1=9

Hope it helps.
Have a nice day noona/hyung ￣▽￣
Answer:
y=4, n=16
Step-by-step explanation:
4y+3=19
4y=19-3
4y=16
y=16/4
y=4
1/2n-3=5
1/2n=5+3
1/2n=8
n=8÷1/2
n=8/1×2/1
n=16

Answer:
I think the answer is 8.
Step-by-step explanation:
The lengths of the sides of a triangle are given below. Classify the triangle as acute, obtuse, or right.
13, 14, 17
A. Acute Triangle
B. Obtuse Triangle
C. Right Triangle
Answer:
A. Acute TriangleStep-by-step explanation:
Lets verify with Pythagorean:
17² = 28913² + 14² = 169 + 196 = 365289 < 365The angle opposite to a greater side is less than 90° and the sum of the squares are close.
It means all three angles are less than 90°.
With this the triangle is acute.
Correct choice is A.
HELP WILL GIVE YOU Brainiest!!!
Answer:
Step-by-step explanation:
So there we have it, <A=135° and <B=45°. This should check when you add them together ("<A and <B are supplementary which means that together their angles equal 180°"). Does 135°+45=180°? YES!

Answer:
this is the answer!
Step-by-step explanation:
Solve the equation 18+a= -50
Answer:
-68
Step-by-step explanation:
Subtract 18 from each side of the equation.
a + 18 = -50
-18 -18
Turn -50 - 18 into -50 + (-18) because you need to add the opposite.
a = -50 + (-18)
a = 68

What is the value of x?
40"
X
55
O A. 85°
O B. 105°
O c. 75°
D. 95°
Answer:
A. 85°
Step-by-step explanation:
By interior angle sum theorem of a triangle.
x = 180° - ( 40° + 55°)
x = 180° - 95°
x = 85°
Answer:
A. 85
Step-by-step explanation:
Youd do 40+55 and that equals 95 and then since a triangle qdds up to 180 degrees, 180-95=85

what is the leading coefficient ? 6x+2x(3)-5
Answer:
2
Step-by-step explanation:
The correct order in which the equation is written would be:
[tex]2x^{3} + 6x - 5[/tex]
So, when ordered correctly the leading coefficient is the first number, so with this equation that would be 2.
Solve the one step inequality.
x − 3 ≥ 6
options:
x ≥ 9
x ≤ 9
x ≥ 3
x ≤ 3
Answer:
x≥9
Step-by-step explanation:
I hope this helps you
Answer:
A. x ≥ 9
Step-by-step explanation:
To get the answer you first move all of the terms not containing a variable, to the right side of the inequality. This would cause you to add 3 and 6, giving you 9. To get your answer of x ≥ 9. Hope this helps... have a great day! :))
