When I have walked 20% of the way to school, I have 1200 metres more to walk than when I have 20% of the walk remaining.
How far, in metres, is it from my home to my school?
Given:
I have walked 20% of the way to school.
I have 1200 metres more to walk than when I have 20% of the walk remaining.
To find:
The distance from home to school.
Solution:
Let x be the distance from home to school.
I have already walked 20% of the way to school and i have 1200 metres more to walk than when I have 20% of the walk remaining.
It means 1200 is [tex]100\%-20\%-20\%=60\%[/tex] of the total distance from home to school.
[tex]1200=\dfrac{60}{100}x[/tex]
[tex]1200=0.6x[/tex]
[tex]\dfrac{1200}{0.6}=x[/tex]
[tex]2000=x[/tex]
Therefore, the distance from home to school is 2000 metres.
How far, in metres, is it from my home to my school is 2,000 metres.
First step is to formulate
1200/(1-2×20%)
Second step is to find how far in metres
Distance=1200/(1-0.4)
Distance=1200/0.6
Distance=2,000
Inconclusion how far, in metres, is it from my home to my school is 2,000 metres.

Answer:
18
Step-by-step explanation:
A left skewed data is one which it's tail is to the left of the distribution. This means the data is negatively skewed. One of the difference various characteristics of a left skewed data wh in could help find an answer to the question is that, for a left skewed distribution, the mean of the data is lower lesser than other measures of center and the mean falls to the left side of de of the peak. Hence, to create a data that is left skewed, we add the value from the options which will decrease the initial value of Mean.
From. The options ; adding 34 and 32 will increase the value the mean.
However, adding 18 will decrease the value value of the initial mean and hence, shift to the left of the peak.

multiply. write your answer as a fraction in simplest form: 4 x 5/14
Answer:
Most simplified version is 1 3/7
Step-by-step explanation:
First step is turn everything into a fraction 4 into a fraction is 4/1
4/1 times 5/14 is 20/14 or 1 and 6/14 or 1 and 3/7
Here we have a problem with the multiplication of fractions.
We will find that:
[tex]4 \cdot\frac{5}{14} = \frac{10}{7}[/tex]
First, two things we need to remember:
[tex]\frac{x}{y} \cdot\frac{a}{b} = \frac{x \cdot a}{y \cdot b}[/tex]
Also, an integer number N can be written as:
[tex]N = \frac{N}{1}[/tex]
Now we want to solve:
[tex]4 \cdot\frac{5}{14}[/tex]
Using the above relations we get:
[tex]4 \cdot\frac{5}{14} = \frac{4}{1} \cdot\frac{5}{14} = \frac{4 \cdot5}{1 \cdot14} = \frac{20}{14}[/tex]
Now we need to simplify this, to do it, we need to divide both numerator and denominator by the same number.
We can see that both are multiples of 2, so if we divide both by 2 we get:
20/2 = 10
14/2 = 7
Then we have:
[tex]\frac{20}{14} = \frac{10}{7}[/tex]
Now 7 and 10 do not have common factors, so we can't simplify it anymore.
Concluding, we get:
[tex]4 \cdot\frac{5}{14} = \frac{10}{7}[/tex]

Determine the equation of the line that passes through the given points. (If you have a graphing calculator, you can use the table feature to confirm that the coordinates of both points satisfy your equation.)
(10, 2) and (-3, 2)
a.
y = 2 x
b.
y = 2 x minus 3
c.
y = 2
d.
y = 2 x + 10
Please select the best answer from the choices provided
A
B
C
D
Answer:
c). y = 2
Step-by-step explanation:
We can check a line by inputting the x and y from (x, y) into the equation.
For a. y = 2x we get
2 = 2*10 and 2 = 2*(-3), both of those are false
For b. y = 2x - 3 we get
2 = 2*10 - 3 and 2 = 2*(-3) + 10, both of those are false again
For c. y = 2 we get
2 = 2 and 2 = 2, both of those are true, so this is the right answer.
For d. y = 2x + 10 we get
2 = 2*10 + 10 and 2 = 2*(-3) + 10, both of those are false
Alternatively, we can solve the equation y = ax + b (this gives a single answer for any two points with different x's).
y = ax + b
We input (x, y) as (10, 2) and (-3, 2)
2 = a*10 + b = 10a + b
2 = a*(-3) + b = b - 3a
so we have
10a + b = b - 3a
13a = b - b
13a = 0
a = 0
Now we ca use a = 0 to solve either of the equations above:
2 = 10a + b
2 = 10*0 + b
2 = b
so with a=0 and b=2 we get the answer
y = 0*x + 2
y = 2
Which brings us to answer c. again.

C. −60
D. −2
part a

The y - intercept is the graph corresponds to the rate at which Mia spends the quarters.
And, The value of slope will be 2.
What is Equation of line?The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
She spends them at a rate of two every minute until she runs out.
Now,
Since, She spends them at a rate of two every minute until she runs out.
And, The number of quarters Mia has is graphed over time.
We know that;
Usually we represent the independent variable (time) by x and dependent variable (quarters) by y.
Hence, The y - intercept is the graph corresponds to the rate at which Mia spends the quarters.
So, The slope = 2/1
= 2
Thus, The y - intercept is the graph corresponds to the rate at which Mia spends the quarters. And, The value of slope will be 2.

for $35.19 each.
What is the greatest number of outfits Elizabeth can buy with the money that's left
over?
Answer: 5 outfits
Step-by-step explanation: 17.63x2=35.26
437.63+35.26+18.11=491
