Answer:
x = 11
Step-by-step explanation:
all angles in a triangle will add up to 180.
So we can start with the equation:
(19 + x) + (7 + 8x) + angle str = 180.
we are given the angle stv. This angle equals 125.
the angle of a straight line is 180. In order to find the angle next to another angle like angle stv and str are, all you have to do is subtract the angle from 180.
So to find str:
180 - 125 = 55
we already have one of our angles which is 55
so the equation is now:
(19 + x) + (7 + 8x) + 55 = 180
now do some simple simplification:
(19 + x) + (7 + 8x) + 55 = 180
______________ -55_-55
(19 + x) + (7 + 8x) = 125
26 + 9x = 125
-26_____-26
9x = 99
99/9 = 11
x = 11
Therefore, x = 11

An industrial machine made 1,629 cans of diet sodas and 6 times as many
regular sodas over the course of 46 minutes. The regular sodas were then
placed into 3 shipping boxes with each shipping box containing the same
number of sodas. How many regular sodas were in each shipping box.
Answers
Each of the shipping boxes contains 2172 cans of regular soda.
Ratios and fractions are the main bases on which proportion is explained. Two ratios are equal when they are expressed as a fraction in the form of a/b, ratio a:b, and then a proportion.
The industrial machine made a total of 1629 cans of diet soda which is 6 times as much regular soda in 46 minutes.
Then, the total number of regular sodas made will be:
R = 4 × Total number of diet soda
R = 4 × 1629 cans
R = 6516 cans
The regular sodas were packed in 3 shipping boxes with each having the same number of soda cans.
Therefore, the number of cans of regular sodas in each box will be:
N = 6516/3
N = 2172 cans
There are 2172 cans of regular sodas in each shipping box.

x - y = 0
EXPLANATION:
Given the coordinates:
A(-3,3)
B(3,3)
C(3,-3) and
D (-3,-3)
One diagonal is line AC.
Find the slope of AC:
[tex]m\text{ = }\frac{y2-y1}{x2-x1}=\text{ }\frac{-3-3}{3-(-3)}=\frac{-6}{6}=\text{ -1}[/tex]Solpe of AC = -1
Using the slope intercept form, y = mx+b, we have:
y = -1x + b
y = -x + b
The equation for AC:
y = -x
The other diagonal is BD.
find the slope of BD:
[tex]m\text{ = }\frac{y2-y1}{x2-x1}=\text{ }\frac{-3-3}{-3-3}=\frac{-6}{-6}=\text{ 1}[/tex]Slope of BD = 1
The equation of BD:
y = 1x
y = x
Therefore the equation of both lines in standard form will be:
AC ==> x + y = 0
BD ==> x - y = 0

B.__ angles form a straight line.
Answers
Complete the sentences
A. All right angles are 90 degrees (by definition)
B. supplemenatry angles form straight line (by definition)
C. If two angles form a linear pair, then the are supplementary (by definition)
D. When two lines intersect, the inverse angles are congruent.
In the given image of two intersecting lines, you have m∠1 = 67°
E. angle 2 and angle 1 are supplementary, then;
m∠2 + m∠1 = 180°
m∠2 = 180° - m∠1
m∠2 = 180° - 67°
m∠2 = 113°
F. angle 3 and angle 1 are congruent, then:
m∠3 = m∠1 = 67°
Due to the given image, you have the following expressions:
2x + x + 60° = 180° supplementary angles
3x + 60° = 180° subtract 60 both sides
3x = 180° - 60°
3x = 120° divide both sides by 3
x = 120/3
x = 40°
Furthermore, for y, you have:
x + y + y + 20° = 180° supplementary angles
x + 2y + 20° = 180° replace x = 40
40 + 2y + 20° = 180°
2y + 60° = 180° subtract 60 both sides
2y = 180° - 60°
2y = 120°
y = 120/2 divide by 2 both sides
y = 60°
Answer: 180 degree's make up a straight line.

This hutch is made up of two rectangular prisms. 1 7 ft 2 ft 2 127 ft 22 ft 4 ft What is the total volume of this hutch, in cubic feet?
Answers
Answer
40 cubic feet
Step-by-step explanation
The volume of a rectangular prism is calculated as follows:
[tex]V=whl[/tex]where w is the width, h is the height and l is the length of the prism.
The hutch is made up of two rectangular prisms, one with a width of 1 1/3 ft, a height of 2 1/2 ft, and a length of 4 ft. The other one has a width of 2 2/3 ft, a height of 2 1/2 ft, and a length of 4 ft.
To calculate the volume of the hutch, first, we need to calculate the volume of each prism, and then add them.
The volume of the smaller prism is:
[tex]\begin{gathered} V_1=1\frac{1}{3}\cdot2\frac{1}{2}\cdot4 \\ V_1=13\frac{1}{3}\text{ cubic feet} \end{gathered}[/tex]The volume of the bigger prism is:
