Answer:
4. 120
5. 20
6. 55
Step-by-step explanation:
All straight lines have a degree of 180, so the angle measures all have to add up to 180 degrees.
Answer:
4) 120°
5) 20°
6) 55°
Step-by-step explanation:
4) 180°-60°=120°
5) 180°-160°=20°
6) 90°+35 = 125°
180°-125°=55°

What is the value of 58 ? (1 point)
Answers
Answer:
1/25
Step-by-step explanation:
Answer:
Step-by-step explanation: The absolute value of 58 is the distance between 58 and 0 on a number line. See illustration below where x is 58: Since the distance between 58 and 0 on a number line is 58, we get the answer as follows: |58| = 58. Note that the absolute value of 58 can also be written as abs (58) which may be useful to know if you have a good calculator.

Mira and Sasha observed two points, P and Q, on a number line.
A number line is shown from negative 2 to positive 2 with increments of 2 over 8. A point P is shown at the seventh tick mark to the left of 0, and a point Q is shown at the seventh tick mark to the right of 0.
Sasha said that the absolute values of the numbers represented by the two points are different.
Mira said that the absolute values of the numbers represented by the two points are the same.
Which of the following explains who is correct?
A Sasha, because the points are of different signs
B Sasha, because the points are at different locations
C Mira, because each of the two points is 14 over 8 units from 0

Answers
Answer:
5.6
Step-by-step explanation:
Sheryl got the following scores on her spelling tests.
95, 89, 99, 85, 82
Mean = sum of all observations/ Number of observations
Sum of all observations [tex]=95+89+99+85+82=450[/tex]
Number of observations = 5
So,
Mean [tex]=\frac{450}{5}=90[/tex]
Let M denotes the mean
Mean absolute deviation [tex]=\frac{\sum_{i=1}^{n}\left | x_i-M \right |}{n}[/tex]
Put [tex]n=5[/tex]
So,
Mean absolute deviation [tex]=\frac{\sum_{i=1}^{5}\left | x_i-M \right |}{5}=\frac{|95-90|+|89-90|+|99-90|+|85-90|+|82-90|}{5}=\frac{5+1+9+5+8}{5} =\frac{28}{5}=5.6[/tex]

Alex bar and Carl are brothers Alex is the oldest and Carl is the youngest the some of the ages of the three brothers is 42 Alex his age is three more than twice Carl's age the difference between Barts in Carl's ages is seven years how old is each brother
Answers
Answer:
Alex = 19 years
Bart's = 15 years
Carl = 8 years
Step-by-step explanation:
Let us represent their ages as
Alex = x
Bart's = y
Carl = z
the sum of the ages of the three brothers is 42
x + y + z = 42
Alex his age is three more than twice Carl's age
x = 2z + 3
The difference between Barts in Carl's ages is seven years
y - z = 7
y = 7 + z
Hence: we Substitute
x + y + z = 42
2z + 3 + 7 + z + z = 42
Collect like terms
2z + z + z + 10 = 42
4z = 42 - 10
4z = 32
z = 32/4
z = 8 years
Hence, Carl = 8 years old
a) y = 7 + z
y = 7 + 8
y = 15 years.
Hence, Bart's is 15 years old
b)x = 2z + 3
x = 2(8) + 3
= 16 + 3
= 19 years
Therefore, Alex is 19 years old.

When lava is expelled from a volcano, it temperature may vary from 700 degrees Celsius to 1200 degrees Celsius. Write an absolute value equation that represents the minimum and maximum temperatures of lava. Use x to represent the temperature.
Equation:__
Answers
Answer:
Ix - 950°C I ≤ 250°C
Step-by-step explanation:
We are told that the temperature may vary from 700 degrees Celsius to 1200 degrees Celsius.
And that this temperature is x.
This means that the minimum value of x is 700°C while maximum of x is 1200 °C
Let's find the average of the two temperature limits given:
x_avg = (700 + 1200)/2 =
x_avg = 1900/2
x_avg = 950 °C
Now let's find the distance between the average and either maximum or minimum.
d_avg = (1200 - 700)/2
d_avg = 500/2
d_avg = 250°C.
Now absolute value equation will be in the form of;
Ix - x_avgI ≤ d_avg
Thus;
Ix - 950°C I ≤ 250°C

Answers
Answer:
x = 30
Step-by-step explanation:
x + 2x + 3x = 180 (Add like terms)
6x = 180 (Divide both sides by 6)
x = 30
Therefore;
x = 30
2x = 60
3x = 90
3x=90
2x=60
If you are referring m as x then first we need to understand and realize how a triangle will ALWAYS equate to 180°.
With that being said a triangle will always have 3 angles, along with them all being able to be added up at equating 180. In this case all of our angles are related to x. We want to first add up all of our angles to equal 180 (x+2x+3x=180 OR 6x+180.) now that we have our equation, we want to solve for x so we need to isolate x first, in order to get 6 out of 6x we must divide by 6 on both sides of the equation which will then give us 180/6=30.
With x equating to 30 then we simply plug in our values for the angle. 3(30)= 90, 2(30)= 60 and x=30

y=3x+9
Explanation:
To answer this question, we first have to understand a few key concepts.
1) The equation given (y=3x+9) is written in slope-intercept form, which is y=mx+b.
Heres what the variables mean:
Y=the coordinate
M=the slope
X=the x coordinate
B=the y-intercept (the point on the line that intercepts the y-axis)
2) Parallel lines have the same slope. Using the given equation, we now know that the slope of line s is 3. Therefore, the slope of line t is also 3 (because they are parallel).
So now, this is our equation so far:
y=3x+b
All we need to do now is find b, which we can do by plugging in the coordinate (-6,-9) as the x and y variables.
y=3x+b
-9=3(-6)+b
-9=-18+b
Add 18 to both sides
-9+18=-18+b+18
9=b
And when we plug 9 into y=3x+b, we get:
y=3x+9
(And yes, they are pretty much the same line)

What is a linear equation?
A linear equation is in the form:
y = mx + b
Where m is the slope and b is the y intercept.
Line V W goes through (-1, 5) and (1, 5). Line R S goes through (-5, 3) and (5, 1). Line T U goes through (-1,-2) and (4, -3).
Slope of VW = (5 - 5)/(1- (-1)) = 0
Slope of RS = (1 - 3) / (5 -(-5)) = -1/5
Slope of TU = (-3 - (-2))/(4 - (-1)) = -1/5
Line TU is parallel to line RS and has a slope of -1/5

Brandon bought 6 less than Lance and payed $75 dollars shoes.
That means that 6 shirts cost $75.
We need to divide 6 from 75
75/6 = 12.5
So each shirt costs $12.50.
