5x - 4y + 2z :
5 (-8) - 4 (3) + 2 (-4)
-40 - 12 - 8
- 60
3x + 2 (x - 4) = 6x - 8 - x
3x + 2x -8 = 6x - 8 - x
5x - 8 = 5x - 8
Since both sides are equal, it has infinitely many solutions.

A. 3 = 37
B. 1 = 37
C. 2 = 37
Answers
Answer:
C. 2 = 37
Step-by-step explanation:
<2 and 37 are vertical angles and vertical angles are equal
Angle 1 and 37 form a straight line so they add to 180
<1 + 37 = 180
<1 = 180-37 = 143
Angle 3 and 37 form a straight line so they add to 180
<3 + 37 = 180
<3= 180-37 = 143

Answer:
3 inches
Step-by-step explanation:
Volume of a hemisphere = [tex]\frac{2}{3}[/tex]π[tex]r^{3}[/tex]
=> 18π = [tex]\frac{2}{3}[/tex]π[tex]r^{3}[/tex]
=> 18 = [tex]\frac{2}{3}[/tex][tex]r^{3}[/tex]
=> [tex]r^{3}[/tex] = 18 × [tex]\frac{3}{2}[/tex]
=> [tex]r^{3}[/tex] = 27
=> r = [tex]\sqrt[3]{27}[/tex]
=> r = 3 inches
Therefore, the radius of the hemisphere in inches is 3 inches.

Find the mean, median, and mode of the data set. Round to the nearest tenth.
5, 7, 2, 6, 7, 10, 12, 7, 9, 13, 5
Answers
Answer:
The mean is 7.5.
The median is 7.
The mode is 7.
Step-by-step explanation:
To find the mean, add up all the numbers in the data set and then divide the sum by the total number of values.
5 + 7 + 2 + 6 + 7 + 10 + 12 + 7 + 9 + 13 + 5 = 83
83 divided 11 equals 7.5.
To find the median, arrange all the numbers in the data set from smallest to largest and then find the number that is in the middle of the set.
To find the mode, put the numbers in order from least to greatest and count how many times each number occurs. The number that occurs the most is the mode.
