Answer:

x = 8

Step-by-step explanation:

remember:

When two triangles are congruent they will have exactly the same three sides and exactly the same three angles.

The equal sides and angles may not be in the same position (if there is a turn or a flip), but they are there.

based on the figure given:

AB=8 is also equal to BC=x=8

therefore, your x value would be 8

m∠ABD = 90°

Answers

Answer:

a and e

Step-by-step explanation:

All the given option are true.

m∠ABC = 45° (true)

m∠CBD = 45° (true)

m∠ABD = 90° (true)

What is angle bisector ?

angle bisector is the line which divides the given angle into two equal parts.

Here, it is given that the angle [tex]\angle ABD[/tex] is a right angle triangle that is it will make an angle of 90 degree and the angle bisrector BC will divide the angle into two equal part that is [tex]\angle ABC = \angle BCD = 45^{o}[/tex].

Therefore, all the given conditions are true.

Answer:

(1, -1)

Step-by-step explanation:

Given lines

y = -3x + 2y = 5x - 6

They cross at:

-3x + 2 = 5x - 65x + 3x = 2 + 68x = 8x = 1

The y coordinate is:

y = -3*1 + 2 = -1

So the lines cross at point (1, -1)

The sum of one-third a number and twenty-five is as much as twice the number

Answers

Answer:

The number is 15

Step-by-step explanation:

1/3(number) + 25 = 2(number)

subtract 1/3(number) from each side

25 = 2(number) - 1/3(number)

25 = 6/3(number) - 1/3(number)

25 = 5/3(number)

multiple each side by 3/5, which is the reciprocal of 5/3

25(3/5) = number

15 = number

What the answer to this math problem 6x-8=4(x+2)-7 ?

Answers

Answer:

x = 9/2

Step-by-step explanation:

6x - 8 = 4(x + 2) - 7

Distribute on the right side.

6x - 8 = 4x + 8 - 7

Combine like terms on the right side.

6x - 8 = 4x + 1

Add 8 to both sides. Subtract 4x from both sides.

2x = 9

Divide both sides by 2.

x = 9/2

Identify the property used in each step of solving the inequality 3x – 2 > -4.
Step Justification
3x - 2-4 Given

3x > -2

X>-2/3

Answers

Answer:

2) is addition property

3) is multiplication property

Step-by-step explanation:

The addition property and division properties are used to solve the inequality.

What is Inequality?

A relationship between two expressions or values that are not equal to each other is called 'inequality.

The given inequality is 3x – 2 > -4.

Three times of x minus two is greater than minus four

By using addition property we add +2 on both the sides

3x – 2 +2 > -4+2

3x>-2

By using division property we divide +3 on both the sides

x>-2/3

Hence, the addition property and division propertys are used to solve the inequality.

Find the mean, median, and mode of 13, 30, 16, 19, 20, 22, 25, 31

Answers

Answer:

Mean: 22

Median: 21

Mode: No mode

Step-by-step explanation:

Mean:

The sum is the value of all the values divided by the number of values:

[tex]13+30+16+19+20+22+25+31/8[/tex] which is 22.

Median:

The median is the middle-most value of the data set when arranged from lowest to highest:

13, 16, 19, 20, 22, 25, 30, 31

Here, since there are two middle-most terms, the median would be the average of 20 and 22 (20+22/2), which is 21.

Mode:

The mode is the most occurring value in the data set.

13, 16, 19, 20, 22, 25, 30, 31

Since, in this data set, there is do value that occurs twice, we can say that there is no mode for this data set.

For a triangle, m<1 =75 and m<3 =40 what does m<2 =?

Answers

Answer:

m<2 = 65

Step-by-step explanation:

The measures of angles 1 and 3 should be added together resulting in 115 degrees, and all triangles equal 180 degrees. Therefore, to find m<2, you have to subtract 115 from 180 resulting in a measure of 65 degrees.

Step-by-step explanation:

Price assuming he bought all large flags: [tex]20*8=160[/tex]

Amount of money more: [tex]160-112=48[/tex]

Difference of price in both flags: [tex]20-12=8[/tex]

Medium Flags: [tex]48\div8=6[/tex]

Large Flags: [tex]8-6=2[/tex]

----------------------------------

The reason why this works, is because the amount of money more comes from the difference between both flags.

What is an expression?

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The price of the ring before the tax was added is,

106.7% ( x ) = 1707.20

( x ) = 1707.20/106.7

( x ) = 16

( x ) = 16x100 = $1,600

Step-by-step explanation:

A function is discontinuous if the limit of the function value approaching the point from the left is different than the limit approaching from the right.

Here, the left limit is 2 and the right limit is 1/2. The limits are different, which is why the function is discontinuous at x=-1.
