Answer:
2. Addition property of inequality. You're adding 6x to both sides.
3. 4x = 28
4. 4x/4 = 28/4 Justification: Division property of inequality
You're dividing both sides by 4.

Answer:
x = 15°
Step-by-step explanation:
7x + 28° = 133° { being vertically opposite angles }
7x = 133° - 28°
7x = 105°
x = 105° / 7
x = 15°
< WPZ = 133° {being vertically opposite angles }
OR
< WPZ = 7x + 28° = 7 * 15 + 28° = 133°

Answer:
A
Step-by-step explanation:
slope rise/run= -4/ 5
plugging it in we get
y= -4/5x+b
-3=-4/5x+b
-3= -4/5(0) +b
-3=0+b
b=-3
so we get y= -4/5x-3

Answer14. 6/0 15. 1/5 OR 5/1
Step-by-step explanation:
subtract and write the difference in simplest form 12 5/8 - 7 1/3
Answer:
5 7/24
Step-by-step explanation:
Given the following mathematical expression;
12 5/8 - 7 1/3
First of all, we would subtract the whole numbers;
12 5/8 - 7 1/3 = (12 - 7) 5/8 - 1/3
12 5/8 - 7 1/3 = 5 [5/8 - 1/3]
Next, we subtract the fractions from each other;
5/8 - 1/3
Lowest common multiple (lcm) = 24
5/8 - 1/3 = (15 - 8)/24
5/8 - 1/3 = 7/24
Combining the two parts, we have;
12 5/8 - 7 1/3 = 5 7/24

You are the manager of a restaurant that delivers pizza to college dormitory rooms. You have just changed your delivery process in an effort to reduce the mean time between the order and completion of delivery from the current 21 minutes. A sample of 36 orders using the new delivery process yields a sample mean of 22.4 minutes and a sample standard deviation of 6 minutes.
A.) Please compute the test statistic. Please round to four decimal places.
B.) Please determine the p-value. Please round to four decimal places.
C.) Using a 0.05 level of significance, please provide the critical value for the appropriate test. Please round to four decimal places.
D.) Using a 0.05 level of significance, is there evidence that the population mean delivery time has been reduced below the previous population mean value of 25 minutes?
Answer:
1.4000 ;
0.0807 ;
1.69 ;
Fail to reject the Null
Step-by-step explanation:
Given :
μ = 21 minutes
x = 22.4 minutes
Sample size, n = 36
Standard deviation, s = 6
H0: μ ≥ 21
H1: μ < 21
Test statistic : (x - μ) ÷ s/sqrt(n)
Test statistic : (22.4 - 21) ÷ 6/sqrt(36)
Test statistic : 1.4 ÷ 1
Test statistic = 1.4000
Pvalue : Using the Test statistic value at α = 0.05 ; One - tail test = 0.0807
The t critical value using a critical value calculator ; DF = (n - 1) = 36 - 1 = 35 ; α = 0.05 = 1.69
Decision region :
Reject H0 if
|Test statistic| > |critical value|
1.4 < 1.69
Hence, we fail to reject H0
There isn't enough evidence they delivery time has been reduced below previous mean

PLEASE HELP!!!!!!!!!!! A clown has two performances today, in cities A and B, which are 240 km apart. The clown drives from City A to City B at a certain speed and performs. On his way back to City A, he drives half the distance at the same speed as before, but then increases his speed by 10 km/h to be on time for his performance in City A. Thus, the drive from B to A takes 2/5 of an hour less than the drive from A to B. At what speed does the clown drive from A to B?
Answer: 50 km/hr
240 = rt
120 = rt1
120 = (r+10)t2
t1 + t2 = t - 2/5 ==> t2 = 1/2 t - 2/5
So you get
240 = rt
120 = (r + 10)(1/2 t - 2/5)
Solve the system
You het 50 km/hr
A figure is graphed in the coordinate plane. Which pair of transformations will NOT preserve the size and the shape of the figure?
A. Reflect the figure over the line y = x and then translate it 2 units up
B. Translate the figure 3 units to the left and then dilate by a scale factor of 4
C. Rotate 90 degrees counterclockwise and then dilate by a scale factor of 1
To state the figure 180 degrees counter-clockwise about the origin and then reflect it over the y-axis
The transformations which is NOT preserve the size and the shape of the figure is dilate by a scale factor of 4 (B) and dilate by a scale factor of 1 (C).
What is the dilation of the figure?Dilation of a figure, means the transformation of the figure. The factor by which the given figure dilated, called the scale factor of dilation.
When a figure is dilated, the size of the original figure is changed.
A figure is graphed in the coordinate plane. Let's check all the option for the transformation of original figure.
A. Reflect the figure over the line y = x and then translate it 2 units up- Reflection and translation of a figure does not changes its shape and size.B. Translate the figure 3 units to the left and then dilate by a scale factor of 4- With the scale factor of dilation, the size of the figure will be changed for this case.C. Rotate 90 degrees counterclockwise and then dilate by a scale factor of 1- In this case, there the figure is dilated with a scale factor of 1. This will change the size of the original figure.D. To state the figure 180 degrees counterclockwise about the origin and then reflect it over the y-axis- In this case the shape and size does not change.Hence, the transformations which is NOT preserve the size and the shape of the figure is dilate by a scale factor of 4 (B) and dilate by a scale factor of 1 (C).

Answer:
Octagon:
Sum = 1080
One interior angle = 135
14-gon:
Sum = 2160
One interior angle = 154.286
20-gon:
Sum = 3240
One interior angle = 162
Step-by-step explanation:
Sum of angles in a polygon -> sum of angles = (n – 2)180°
one interior angle = sum of angles/n
n = number of sides
one interior angle = sum of angles/n
Octagon:
Sum = 1080
One interior angle = 135
14-gon:
Sum = 2160
One interior angle = 154.286
20-gon:
Sum = 3240
One interior angle = 162
Find the measure of the supplement of a
16° angle.
Answer:
164
Step-by-step explanation:
Hey There!
If they are supplementary angles then they will add up to equal 180
So given one of the angles (16) we subtract that from 180 to find the value of the missing angle
180-16=164
Your answer is 164
