The equation that calculates the time taken to get to Springfield is x = 926/57
What is rate?Rate is used to establish the relationship between two quantities of different units. one of the quantity is usually expressed to unity in order to estimate the change in the other quantity.
If Hillwood and Springfield are 926 mile apart, and the speed taken to get to Springfield is 57miles per hour.
Let the time taken to get to Spring field be x.
Then if 57 miles is covered in an hour and it takes x hours to get to the destination
It means total distance covered is 57 × x
This distance is equal to the distance from Hillwood to Springfield which is 926 miles.
Equating both equations.
57x = 926
In conclusion, 57x = 926 is the equation that can be used to find out the time taken.

What is defined by the term linear pair?Linear pairs of angles are generated when two lines intersect at a single point. If the angles formed are adjacent to one another after the two lines intersect, the angles are referred to as linear. When two angles form a linear pair, their measures add up to 180°. As a result, a linear pair of angles everytime sum to 180°.From the given question;

The plot of the points on a coordinate plane is added as an attachment
How to plot the point on a coordinate plane?The coordinate of the point on a coordinate plane is given as
Point = (-3 1/2, -1 1/4)
As a general rule, we express the above coordinate as follows:
(x, y) = (-3 1/2, -1 1/4)
The next step is to remove the bracket
So, we have the coordinates into x and y coordinates
This is represented as
x = -3 1/2 and y = -1 1/4
The interpretation of the above equations is:
(-3 1/2, -1 1/4) is at a point that is 3 1/2 points to the left of the origin (-3 1/2, -1 1/4) is at a point that 1 1/4 points below the originNext, we plot the points

Find the equation of the line with slope m = - 1/3 and passing through the point (1, 1/3)
(Write the equation in standard form.)
answer has to be in the form ax+by=c
The equation of the line is x + 3y = 2
What are linear equations?Linear equations are equations that have constant average rates of change.
How to determine the equation of the line?The given parameters are
Slope, m = -1/3
Points (x, y) = (1, 1/3)
A linear equation is represented as
y = slope * (x - x₁) + y₁
Where
(x₁, y₁) = (1, 1/3)
Substitute (x₁, y₁) = (1, 1/3) and Slope, m = -1/3 in the equation y = slope * (x - x₁) + y₁
So, we have
y = -1/3* (x - 1) + 1/3
Multiply through by 4
So, we have
3y = -(x - 1) + 1
Remove the brackets
3y = -x + 1 + 1
So, we have
x + 3y = 2
Hence. the linear equation is x + 3y = 2

A house purchased for $265,100 gains 2% of its value every year. If this growth rate continues, in how many years will the house be worth twice its original value
The price of the house will double the original value in 35 years
How to determine the number of years?The given parameters from the question are
Initial value of the house = $265,100
Rate of gain = 2% of its value every year
An exponential function is represented as
y = a *(1 + r)^x
Where
y represents the current valuea represents the initial valuer represents the growth or decay ratex represents the number of years, in this caseThis means that
a = 265,100
r = 2%
So, we have
y = 265,100 *(1 +2%)^t
When the price doubles, we have
2 * 265,100 = 265,100 *(1 +2%)^t
Divide both sides by 265,100
So, we have
2 = (1 +2%)^t
Evaluate the sum
So, we have
2 = 1.02^t
Take the logarithm of both sides
t * log(1.02) = log(2)
Divide
t = log(2)/log(1.02)
Evaluate
t = 35
Hence, the number of years is 35

How to illustrate the information?It should be noted that because the normal distribution is symmetrical on both sides of the mean and is a continuous probability distribution, the right side of the center is the opposite of the left side.
The normal distribution was first termed by early statisticians who observed that the same shape repeatedly appeared in many distributions. The characteristics of normal distributions are as follows: Bell-like in its symmetry. The distribution's mean and median, which are both at its center, are equal.
The area will be illustrated as:

Jacob and Diego are racing to see who can get his community service hours for scouting completed first. Jacob, who has already completed 50 hours, plans to volunteer for 5 hours per week going forward. Diego hasn't started yet, but plans to dedicate 6 hours per week to his volunteer project from now on. Before too long, the boys will be tied, with the same number of volunteer hours. How long will that take?
Using system of equation, the solution shows that it will take 50 weeks before Jacob and Diego will be tied in the race to complete community service hours for scouting.
As given,
let us assign the unknown quantity (number of weeks) a variable x.
Jacob plans to devote 5 hours per week from now onwards. Hence his volunteer hours will cumulate to 5x+50 as he has already completed 50 weeks.
Diego plans to devote 6 hours per week from now onwards. Hence his volunteer hours will cumulate to 6x.
For Jacob and Diego to tie in the race, their volunteer hours should be equal.
Solution of the system of equation is given by:
6x = 5x+50
=> 6x-5x = 50
=> x = 50
Therefore, using system of equation, the solution shows that it will take 50 weeks before Jacob and Diego will be tied in the race to complete community service hours for scouting.

a group of students asked Pythagoras how many students were in his class. "One half study mathematics, one quarter study natural philosophy, one seventh observe silence and there are three others", How many students did he have?
the total number of students in class is given by the equation x - 1 / 2 x - 1 / 4 x - 1 / 7 x = 3 and is equal to 28.
Let the total number of students be x
Mathematics = 1 / 2 x
natural philosophy = 1 / 4 x
Silence = 1 / 7 x
Remaining = 3
So, we get the equation as:
x - 1 / 2 x - 1 / 4 x - 1 / 7 x = 3
(28 x - 14 x - 7 x - 4 x) / 28 = 3
3 x / 28
x = (3 × 28) / 3
x = 28
Number of students in class = 28.
