M is the midpoint of LN. If LM = 3x - 7, and MN = x - 3, find x
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

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°
Esmeralda draws a scale drawing of a rectangular community garden she helps manage. The scale factor from the drawing to the garden is 20. Based on the measurements of Esmeralda's drawing, what is the perimeter of the community garden?
Answer:
20
Step-by-step explanation:
The perimeter of the community garden is 130 unit.
What is Scale Factor?A scale factor is a numerical value that can be used to alter the size of any geometric figure or object in relation to its original size. It is used to find the missing length, area, or volume of an enlarged or reduced figure as well as to draw the enlarged or reduced shape of any given figure. It should be remembered that the scale factor only affects how big a figure is, not how it looks.
Given:
Scale factor = 20
After Scale factor the Dimension are
l = 2 1/4 x 20 = 9/4 x 20
l = 45
and, w = 1 x 20 = 20
So, Perimeter of rectangular Garden = 2( l +w)
= 2 ( 45+20)
= 2 ( 65)
= 130 unit.
Hence, the Perimeter is 130 unit.

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?
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

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]

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?
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)
What is the value of s in the equation 4(2s - 1) = 75 + 12?
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

I WILL GAVE BRAINLIEST!!!!!!!!!!!!!!!!!!!
Answer:
31
Step-by-step explanation:
Recognize that all angles of a triangle add up to 180 degrees, so your equation would be x + 16 + x + 24 + 78 = 180.
Step 1: Combine like-terms.
2x + 118 = 180
Step 2: Subtract 118 from both sides to isolate the variable.
2x = 62
Step 3: Simplify
x = 31
Find the measures of all four angles if m∠2 − m∠1=30°
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°
