What is the answer to this question? The difference of x and 22 is equal to 8
Answer:
If the difference of x and 22=8
then equation is
X -22=8
X=22+8
X=30
therefore now we put the value of x in the equation
30-22=8
8=8
Answer:
x would be 30
Step-by-step explanation:
x-22=8
x=8+22
x=30

If 5 men can do a piece of work in 20 days, in how many days could 10 men
do the same work?
Answer:
10
Step-by-step explanation:
(U can do mental calculation and guess it will be 10 ..) or else ....
Constant(k) = xy
k= 5 x 20
k= 100
Constant(k) = xy
100 = xy
100 = 10y
y= 100/10 = 10
= 10
I hope im right!!

The scale on a map reads 2 inches = 125 miles.
If two cities are 4 inches apart on the map.
what is their actual distance?
Answer:
500 miles
Step-by-step Explanation:
We are told that
1 inch = 125 miles meaning if the distance between two points on the map is 1l inch, then it's 125 miles in real life. However, the map distance between the two cities is 4
inches, therefore it is 4 inches
×
125 miles
1 inch
=
500 miles

Answer:
(5, 1) or maybe (h, k)
Step-by-step explanation:
The given form has no letters other than the variable. The vertex in this vertex-form equation can be read from the expression as (5, 1).
In the generic vertex form ...
f(x) = a(x -h)² +k
the letters (h, k) are used to represent the vertex.
__
You would need to consult your curriculum materials to see what letters your author uses for the vertex in vertex form.

What is the simple interest rate on a $2300 investment paying $906.20 interest in 19.7 years?
Answer:
2%
Step-by-step explanation:
Given data
Principal=$2300
Simple interest=$906.20
Time= 19.7years
Required
The rate in percentage
We know that
SI=PRT/100
substitute
906.20=2300*R*19.7/100
906.20=45310R/100
cross multiply
906.20*100= 45310R
90620= 45310R
R= 90620/45310
R=2%
Hence the rate is 2%
please help me with these two problems
Problem 1
With mean = median, the data set is symmetrical. Well it's more accurate to say "roughly symmetrical" due to the phrasing "mean is approximately equal to the median". Using the median as its center is fairly common with many distributions, so there isn't an issue here.
The error is from the phrasing "the quartiles should be used to measure the spread". The quartiles themselves don't measure spread. They are simply single data points and do not tell us the spread. If Ralph said Q3 = 75 is a measure of spread, then he would be incorrect. However, the difference between the third and first quartile will help get the IQR (interquartile range), as described by this equation below
IQR = Q3 - Q1
and this is one tool to measure how spread out data is. The larger the IQR is, the more spread out the data will be.
The IQR is how far of a gap it is from Q1 to Q3. Another tool to measure spread is the standard deviation. Ralph was probably thinking about the IQR when he mentioned the quartiles, but he should be more specific about what he means.
=======================================================
Problem 2
Answer: Skewed left
This is the same as saying "negatively skewed"
---------------
Explanation:
The main cluster of values is on the right side, while a small portion of values are to the left. We consider this the left tail and the left tail is pulled longer compared to the right tail. The further left we go, the shorter the bar and eventually we hit outliers. These much smaller outliers compared to the main cluster pull on the mean to make it smaller than it should be.
One example could be that this curve represents test scores. The majority of the class could get in the range of say 70 to 90. Then there's the unfortunate few outliers who scored much lower (possibly 40 through 60); those outlier scores pull down the mean grade of the class overall.
In short, negatively skewed data indicates that mean < median.
Which of these is an example of a literal equation?

[tex]L_{1}[/tex] ⊥ [tex]L_{2}[/tex] ; [tex]L_{3}[/tex] ⊥ [tex]L_{2}[/tex] ; [tex]L_{1}[/tex] ║ [tex]L_{3}[/tex]
Step-by-step explanation:
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
y = mx + b
"m" is slope
"b" is y-intercept (coordinates are (0, b)
Parallel lines have the same slopes and different y-intercepts.
Slopes of perpendicular lines are opposite reciprocals: [tex]m_{1}[/tex] × [tex]m_{2}[/tex] = - 1
~~~~~~~~~~~~~~~~~~~~~~
[tex]L_{1}[/tex] : y = x + 5 , [tex]m_{L_{1} }[/tex] = 1 , b = 5
[tex]L_{2}[/tex] : y = - x + 7 , [tex]m_{L_{2} }[/tex] = - 1 , b = 7

Give l m n find the value of x
Answer:
x=13
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
9x+17 + 3x+7 = 180
Combine like terms
12x +24 =180
Subtract 12 from each side
12x+24-24 =180-24
12x =156
Divide each side by 12
12x/12 =156/12
x=13
