Answer:
Two expressions are equivalent if they can be simplified to the same third expression or if one of the expressions can be written like the other. In addition, you can also determine if two expressions are equivalent when values are substituted in for the variable and both arrive at the same answer.

Hello:
Let's consider what the question asks for:
--> find the value of 'x'
The two angles given are supplementary
--> as together
--> they form a straight line which represents a total of 180 degrees
--> in mathematical form
[tex](x+19)+(7x+9)=180\\x+19+7x+9=180\\8x+28=180\\8x=152\\x=19[/tex]
Answer: 19
58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57
If a value of 60° is added to the data, how does the median change?
Answer:
The original data set:
57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105
Finding the median:
77 and 82 are the 2 middle numbers
57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105
Do 77 + 82 which equals 159
Then do 159 ÷ 2 which would be 79.5
The median for the original data set would be 79.5
Then adding the 60° would make a new data set:
57, 58, 60, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105
The middle number would be 77
57, 58, 60, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105
So the median for the second data set would be 77.

Explain how to determine whether two quantities are proportional.
Step-by-step explanation: Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio. That is, when you divide any pair of the two values, you always get the same number k.

Question #1: 17 Miles
Question #2: 10 units
Step-by-step explanation:
Question #1: Here we are using the Pythareom Theorem [tex]\sqrt{a^{2}+b^{2} } =c^{2}[/tex]
We must plug in the horizontal distance (x) from a to c (-4 to 4 = 8).
Then we take the vertical distance (y) from a to c (-6 to 9 = 15).
Plug it all into the Pythareom Theorem[tex]\sqrt{8^2+15^2} =17[/tex]
Question 2: We do the same thing just using the new values

Step-by-step explanation:
The diagonal of a television measures 27 inches. If the width is 22 inches, calculate its height to the nearest inch.
Answer:
16 inches
Step-by-step explanation:
We can use the Pythagorean theorem to find the height of the television. The Pythagorean theorem states that in a right triangle, the sum of the squares of the lengths of the two smaller sides is equal to the square of the length of the longest side (the hypotenuse). In this case, the diagonal of the television is the hypotenuse and the width and height are the other two sides.
So, we can set up the equation as follows:
a^2 + b^2 = c^2
where a is the width (22 inches), b is the height, and c is the diagonal (27 inches).
We can solve for b:
b^2 = c^2 - a^2
b^2 = 27^2 - 22^2
b^2 = 729 - 484
b^2 = 245
b = √245
b = 15.56 inches (rounded to two decimal places)
So, the height of the television to the nearest inch is 16 inches.

Answer:
X = 69
Step-by-step explanation:
You add the 11x and 58
Answer: hope this helps ♡ (i wont mind getting brainliest )
x = 3
Step-by-step explanation:
z° and 89° are two opposite angles.
z° = 89°
89° + 89° + (11x + 58)° + (11x + 58)° = 360° (adds up to 360° coz its a circle)
178° + (11x + 58)° + (11x + 58)° = 360°
178° + 58° + 58° + (11x + 11x)° = 360°
178° + 116° + 22x° = 360°
294° + 22x° = 360°
294° - 294° + 22x° = 360° - 294°
22x = 66
22x ÷ 22 = 66 ÷ 22
x = 3
(double check: 11×3 = 33 2×(33+58)+178=360° ✓)

Step 1: break down the compound shape into different components.
Step 2: determine the volume of each basic shape.
Step 3: combine the volumes of all the basic shapes
Step 4: write the solution in cubic units.
Also the volume of the three green rectangular prisms is 120 cubic units, I think.

Step-by-step explanation:
In February of 2006, there was a
record snowfall of 26.9 inches in one
day in New York City. The normal
snowfall for the month of February in
New York City is 8.5 inches and March
is 5.1 inches. How much more snow
fell in the one day storm in 2006 than
normally falls in February and March
combined
Answer:
40.5 inches
Step-by-step explanation:
I’m not sure if this is correct or not but my thinking is that you just add 26.9, 8.5, and 5.1 together since it says “How much more snow fell in the one day storm in 2006 than normal falls in February and March combined?” And combined basically means all together.
Answer: 13.3 more inches of snow fell in one day storm than normally falls in February and March combined.
February and March combined: 8.5+5.1 = 13.6
Since the question asked how much more, that means you subtract:
26.9 - 13.6 = 13.3
hope this helped =)
