50 points and brainliest to first correct answer :/

The figure below shows a quadrilateral ABCD. Sides AB and DC are congruent and parallel:

A quadrilateral ABCD is shown with the opposite sides AB and DC shown parallel and equal.

A student wrote the following sentences to prove that quadrilateral ABCD is a parallelogram:

Side AB is parallel to side DC, so the alternate interior angles, angle ABD and angle CDB, are congruent. Side AB is equal to side DC, and DB is the side common to triangles ABD and BCD. Therefore, the triangles ABD and CDB are congruent by SSS postulate. By CPCTC, angles DBC and BDA are congruent and sides AD and BC are congruent. Angle DBC and angle BDA form a pair of alternate interior angles. Therefore, AD is congruent and parallel to BC. Quadrilateral ABCD is a parallelogram because its opposite sides are equal and parallel.

Which statement best describes a flaw in the student's proof?

Question 11 options:

Angle DBC and angle BDA form a pair of vertical angles, not a pair of alternate interior angles, which are congruent.


Triangles ABD and CDB are congruent by the SAS postulate instead of the SSS postulate.


Triangles ABD and BCD are congruent by the AAS postulate instead of the SSS postulate.


Angle DBC and angle BDA form a pair of corresponding angles, not a pair of alternate interior angles, which are congruent.

solve for x -2x+4=3

Answers

Answer:

x = 0.5 or -1/-2

Step-by-step explanation:

-2x + 4 = 3

Subtract 4 on both sides to leave the -2x alone

-2x = -1

Divide by -2 on both sides to isolate the x

x = [tex]\frac{-1}{-2}[/tex]

x = 0.5

Answer:

x = 1

Step-by-step explanation:

x - 2x +4 = 3

x - 2x + 1 = 0

(x - 1 ) (x - 1) = 0

This means that one of the brackets must equal to zero which means that x -  1

Step-by-step explanation:

420/6=70 mins

Answer: 70 minutes

Step-by-step explanation: simply do 420/6 to find out the number of minutes it will take.

You could also do this as a ratio of minutes to cartons 1:6 and find out how many times you must multiply 6 cartons to get to 420 cartons. That number is 70 so just multiply the 1 for the number of minutes because in ratios you must multiply by the same value for each number in the ratio.

Step-by-step explanation:

[tex]\frac{83 in}{\frac{12 in}{3 in} } =2.3[/tex]

Answer:

See below:

Step-by-step explanation:

Hello! My name is Galaxy and I'll be helping you with your problem! Feel free to ask me any questions in the comments if you need it!

We can solve the problem by knowing the following: Conversions and Solving. I'll start off with Conversions.

Conversions

We can convert the inches to yards by knowing our conversion rates, they are the following:

1 yard = 3 feet.

1 feet = 12 inches.

We can use these factors to solve the problem.

Solving

We can solve the problem by using our base value, inches, and building up from it, to get to yards, we can split 83 into groups of 36 as there are 36 inches in one yard.

[tex]1yd=3ft=36in[/tex]

Now that we know that, 83 is equal to 36+36+11

We have two groups of 36 so we know right now it is 2 yards and 11 inches.

If we don't want it to be precise and not in decimals, that would be our answer, but, if we want it in precise terms, we have to go deeper.

Since we know its 2 yards and 11 inches, we can convert our 11 inches to yards by dividing it by 36.

Leading to that gives us:

[tex]2\frac{11}{36}[/tex] yards is equal to 83 inches.

If we want it as a decimal, it keeps on going but its ~ 2.305556 or rounded down to 2.3 yards!

Answer:

x = 1

y = 4

Step-by-step explanation:

Divide the second equation by 2

2x/2 + 2y/2 = 6/2

x + y = 3

Subtract the new equation from the first equation you were given

3x + y = 1

x   +  y = 3                       Subtract

2x = - 2                            Divide by 2

2x/2 = -2/2

x = - 1

x + y = 3

-1 + y = 3                             Add 1 to both sides

-1 + 1 + y = 3+ 1                   Combine

y = 4

Answers

Answer:

One Solution

x= -7

Step-by-step explanation:

2 times 7x is 14x

2 times 13 is 26

3 times x is 3x

3 times 11 is 33

Now the equation looks like this:

14x+26-16x=3x+33-4x

Now Simplify:

-2x+26=-x+33

Add x on both sides and subtract 26 on both sides:

-x=7

Divide by -1 on both sides:

x=-7

So one solution and the one solution is -7
