M is the midpoint of LN. If LM = 3x - 7, and MN = x - 3, find x
Answers
Answer:
x = 2.5 or 5/2
Step-by-step explanation:
If M is the midpoint it separates the line segment into 2 equal parts so....
3x - 7 = x - 3 ----> + 3 on each side ----> 3x -5 = x ---> - 3x on each side ---> -5 = -2x ----> divide by -2 on each side to get. 2.5

What is the value of s in the equation 4(2s - 1) = 75 + 12?
Answers
Answer:
s=91/8
Step-by-step explanation:
4(2s-1)=75+128s-4=878s=91s=91/8Answer: s=91/8
Step-by-step explanation:
To find the value of s, you want ot use your algebraic properties to isolate s.
4(2s - 1) = 75 + 12 [distribute by FOIL]
8s-4=75+12 [add]
8s-4=87 [add both sides by 4]
8s=91 [divide both sides by 8]
s=91/8
Molly and James tracked the average temperature in their city for the past 8 days. They recorded their temperature findings in this list. 74°F , 79°F , 76°F, 85°F, 87°F, 83°F, 86°F, 78°F What is the mean absolute deviation of this data set?
Answers
Answer:
Mean = 81°F.
S. dev. = 5°F.
Step-by-step explanation:
When we have a set of data:
{x₁, x₂, ..., xₙ}
The mean can be calculated as:
M = (x₁ + x₂ ... + xₙ)/N
Where N is the number of data points that we have:
in this case the set is:
{ 74°F , 79°F , 76°F, 85°F, 87°F, 83°F, 86°F, 78°F }
So N = 8.
Then the mean is:
M = ( 74°F + 79°F + 76°F + 85°F + 87°F + 83°F + 86°F + 78°F )/8
M = 81°F.
Now, the standard deviation can be calculated as.
Sd = √ ( (1/N)*∑(xₐ - M)^2)
where the summation is over xₐ, which represents a summation over all the points in the data set.
Then we can write the standard deviation as:
Sd = √(1/8)*√( (74°F - 81°F)^2 + (79°F - 81°F)^2 + (76°F - 81°F)^2 + (85°F - 81°F)^2 + (87°F - 81°F)^2 + (83°F - 81°F)^2 + (86°F - 81°F)^2 + (78°F - 81°F)^2)
Sd = 4.58°F.
That we should round up to 5°F (because our mean has no digits after the decimal point)

Answer:29° because the angle in between x and 105 is 54(alternate angles) in theory angles on a straight line add upto 180° so therefore x+105+54=180 thus x+159=180 as a result the remaining angle (x) would be 180-159=29° therefore x=29°

Find the measures of all four angles if m∠2 − m∠1=30°
Answers
Answer:
m∠1 = m∠3 = 75°
m∠2 = m∠4 = 105°
Step-by-step explanation:
From the figure attached,
m∠1 + m∠2 = 180° [Supplementary angles]------(1)
Since, m∠2 - m∠1 = 30°
m∠2 = 30° + m∠1 -----(2)
By substituting the value of ∠2 from equation (2) to equation (1),
m∠1 + (m∠1 + 30°) = 180°
2(m∠1) + 30° = 180°
2(m∠1) = 150°
m∠1 = 75°
Therefore, m∠2 = 180°- m∠1 = 180° - 75°
m∠2 = 105°
Since, ∠ 2 ≅ ∠4 [Vertical angles]
m∠2 = m∠4 = 105°
Similarly, ∠1 ≅ ∠3 [Vertical angles]
m∠1 = m∠3 = 75°

Answers
Answer:
Step-by-step explanation:
the pizza come in slices that are 1/8 each.
there are 36 slices, which means [tex]\frac{36}{288}[/tex]. so the simplest form is 1/8 as well. Maria bought 4 pizzas
The total amount of pizza Maria bought as a fraction is [tex]\frac{36}{4}[/tex] and 8 [tex]\frac{1}{2}[/tex] as a mixed number
Total amount bought = fraction of a slice x total slices bought
[tex]\frac{1}{4}[/tex] x 36 = [tex]\frac{36}{4}[/tex]
The above expression is an improper fraction
An improper fraction is a fraction in which the numerator is greater in value than the denominator
36 is greater than 4
A mixed number is a number that is made up of a whole a whole number and a proper fraction.
To convert to an improper fraction to a mixed number:
Divide the numerator by the denominator. The whole number is written down The remainder is the numerator and the denominator in retained[tex]\frac{36}{4}[/tex] = 8[tex]\frac{2}{4}[/tex]
When it is simplified it becomes 8 [tex]\frac{1}{2}[/tex]

Gavin was thinking of a number. Gavin adds 9 to it, then doubles it and gets an answer of 83.2. What was the original number?
Answers
Answer: it is 32.6
Step-by-step explanation:
The orginal number that Gavin was thinking of is 32.60.
What is the original number?
Let the orginal number be represented with y
Gavin adds 9 to the original number: 9 + y
The answer is doubled: 2(9 + y)
The answer is 83.2: 2(9+y) = 83.2
In order to determine the value of y, take the following steps:
Divide both sides of the equation by 2
9 + y = 41.60
Subtract 9 from both sides of the equation
y = 41.60 - 9
y = 32.60
