How many kilograms are there in 45,456 mg?
2x-3 = -x+3 what does x equal
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
x = 2
Hope this helps! :)
Answer:
x = 2
Step-by-step explanation:
2x - 3 = - x + 3
First, combine the like terms
(Don't forget to change the signs with you bring a number or variable from one side to another.)
2x + x = 3 + 3
Then, add or subtract.
3x = 6
Divide.
x = 2

A statistics class with 40 students consists of 30 students with no income, 10 students with small incomes from part-time jobs, and a professor with a very large income that is well deserved. Which is better for describing the income of a typical person in this class: mean or median? Explain.
The median would be better for describing the income of a typical person in the class because the professor's large salary skews the data to the right while all the students are towards the left and center.
Find the perimeter of the polygon with the given vertices Round your answer to the nearest hundredth
Answer:
16.93 units
Step-by-step explanation:
Length of a segment having extreme ends [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,
d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
ML = [tex]\sqrt{(4-1)^2+(0-4)^2}[/tex]
= 5 units
LP = [tex]\sqrt{(1+1)^2+(4+2)^2}[/tex]
= [tex]\sqrt{40}[/tex] ≈ 6.32 units
PN = [tex]\sqrt{(-1-2)^2+(-2-0)^2}[/tex]
= [tex]\sqrt{13}[/tex]
≈ 3.61 units
NM = [tex]\sqrt{(4-2)^2+(0)^2}[/tex]
= 2 units
Perimeter of the polygon MLPN = ML + LP + PN + NM
= 5 + 6.32 + 3.61 + 2
= 16.93 units

Answer:
The median of her scores is 87
Step-by-step explanation:
What is median?
The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers) is called a median.
Arranging the data in ascending order.
56,72,87,89,93.
n=5
Median =[(n+1)/2]th observation.
=[(5+1)/2]th observation
=3rd observation

Write the equation g(x) of the transformation of the parent graph f(x) = |x| reflected over the x axis.
Answer:
g(x) = -|x|
Step-by-step explanation:
f(x) = |x|
y = −f(x) Reflects it about x-axis
g(x) = -|x|
We start off with: f(x) = |x|
Reflection across x-axis
y = -f(x)
After: g(x) = -|x|

\small \overrightarrow{QS} bisects \small \angle PQR. If \small m\angle PQS=5x-11 and \small m\angle RQS=3x+7, than what is \small m\angle PQR? \small m\angle PQR= 8x-4 degrees
Answer:
[tex] m\angle PQR =(8x - 4)\degree[/tex]
Step-by-step explanation:
Since, QS bisects angle PQR.
Therefore,
[tex]m\angle PQR = m\angle PQS = m\angle RQS\\
m\angle PQR =5x - 11 + 3x +7\\
m\angle PQR =5x + 3x + 7 - 11\\
\huge \red {\boxed {m\angle PQR =(8x - 4)\degree}} [/tex]
Write 0.12 as a fraction.
Let x = ?
100x = ?
100x - x = ? - ?
99x = ?
X = ?
Answer:
Let 0.12 be x.
Here, x is recurring in two decimal places so we'll multiply it by 10-
10x = 1.22Now, by subtracting them-
[tex] \\ \implies \sf \: 10x - x = 1.22 - 0.12 \\ \\ \\ \implies \sf \: 9x = 1.1 \\ [/tex]
Now, we'll divide both sides by 9 to get x as a fraction -
[tex] \\ \implies \sf \: x = \frac{1.1}{9} \\ \\ \\ \star \: \large{ \boxed{ \sf{x = \frac{11}{90} }}} \\ [/tex]

Regina is walking to school after 10 minutes, jen has walked 3/10 mile.Find her speed in miles per hour A 2.5 miles B 1.3 miles C 1.8 miles per hour D 3miles per hour
Answer:
B. 1.8miles/hour
Step-by-step explanation:
Speed = distance/time
Given parameters
Distance = 3/10 miles
Time = 10miuntes
Convert the time to hours
10minutes = (10/60)hour
10minutes = 1/6 hour
Substitute the parameters into the formula;
Distance = (3/10)/(1/6)
Distance = 3/10× 6/1
Distance = 18/10
DISTANCE = 1.8miles/hour

ANSWER THIS QUESTION WITH WORKING PLEASE :>!!!
Step-by-step explanation:
y + 65°= 180° (Being co-interior angle)
y = 180° - 65°
y = 115°
Next we will find of the next co-interior angle which is A and D
(2x - 10)° + (3x + 20)° = 180° ( Same reason)
Now we will keep the like ones together.
2x° + 3x° - 10° + 20° = 180°
5x° + 10° = 180°
5x = 180° - 10°
5x = 170°
x = 170°/5
x = 34°
Now we need to find (2x - 10)° and (3x + 20)°
(2x - 10)°
=(2×34-10)°
=(68-10)°
=58°
(3x + 20)°
=(3×34-20)°
=(102-10)°
=92°
