Before school, she earns$11.25/hour, and after school she earns $11..75/hour. Last week, she earned a total of $278. She works twice as many hours after school. How many hours did she work at each job last week?
Last week, Ella worked 16 hours after school and 8 hours before school using the concept of algebraic equations.
What is a mathematical equation?The equality of two mathematical expressions is demonstrated by a mathematical statement called an equation.
Algebraic equations in mathematics frequently have one or more variables.
Given: Ella makes $11.25 per hour before school and $11.75 per hour after.
Total earnings of Ella from = $278
Let x be the number of hours Ella worked before school.
Let y be the number of hours Ella worked after school.
11.25x + 11.75y = 278
Given that she works twice as long after school, it follows that
y = 2x
Substituting in the equation, we get
11.25x + 11.75(2x) = 278
11.25x + 23.5x = 278
34.75x = 278
x = 8
Similarly, y= 2x
y = 16
Ella accordingly worked 16 hours after school and 8 hours before school.

The arithmetic mean of a given data is the sum of all observations divided by the number of observations.
For example, a cricketer's scores in five ODI matches are as follows: 12, 34, 45, 50, 24. To find his average score in a match, we calculate the arithmetic mean of data using the mean formula:
Mean = Sum of all observations/Number of observations
Mean = Sum of all observations/Number of observations
Mean = (12 + 34 + 45 + 50 + 24)/5
Mean = 165/5 = 33
The value of the middlemost observation, obtained after arranging the data in ascending or descending order, is called the median of the data.For example, consider the data: 4, 4, 6, 3, 2. Let's arrange this data in ascending order: 2, 3, 4, 4, 6. There are 5 observations. Thus
median = middle value i.e. 4.
suppose Given data:
0, 40, 60, 70, 75, 80, 85, 95, 95, 100
a)Mean without '0' = 40+ 60+ 70+ 75+ 80+ 85+ 95+ 95+ 100/9

Median without '0' = 80
Mean with ' 0' = 0+ 40+ 60+ 70+ 75+ 80+ 85+ 95+ 95+ 100/10 = 70

what amount of a 60% acid solution must be mixed with a 35% solution to produce 600 mL of a 55% solution? Algebra
2400mL is the amount of 60%acid solution to mix.
Let the amount of acid be mixed be x.
From the question, we get an equation that,
60%x + 35% × 600/ x + 600 = 55%
(Here x ≠ -600, as the denominator can never be 0.)
60%× x + 35% ×600 = 55%(x + 600)
Now we have to find the value of x to know the amount of acid that is mixed in a solution.
0.60x + 0.35 × 600 = 0.55(x+600)
0.60x + 210 = 0.55 + 330
0.05x = 120
x = 120/0.05
= 2400
Therefore we get an amount of acid to be mixed is 2400mL.

Which is an equation of the line that is parallel to y = 2x -8
and passes through the point (0,-3)?
The equation of a straight line that is parallel to y = 2x -8 and passes through the point (0,-3) is y=2x-3 .
The general equation of straight line is of the form y=mx+c where m is the slope of the equation and c is the y-intercept of the equation.
The slope is defined as the tangent of the angle made by the line with the positive direction of x axis.
he y-intercept of a straight line is the point where the graph passes the y-axis.
The given equation of the line is y=2x-8. Comparing the given equation with the general equation of a straight line we can conclude that the slope of the line is 2.
Two parallel lines have the same slope . Therefore the slope of the line parallel to y = 2x -8 is also 2.
We know that if a line with slope m passes through(x₁, y₁) then the equation of the line is given by
y-y₁=m(x-x₁)
The required line passes through (0,-3)
∴putting the values we get:
y-(-3)=2(x-0)
or, y+3=2x
or, y=2x-3
Therefore the line parallel to y = 2x -8 and passing through the point (0,-3) is y=2x-3.

Samuel's test score if he got 9 questions wrong=55
Samuel's test score if he got x questions wrong=45
What is mean scale score?Mean score: A mean scale score is the average performance of a group of students on an assessment. Specifically, a mean scale score is calculated by adding all individual student scores and dividing by the number of total scores. It can also be referred to as an average.
let y equal the number of questions
let's find how many total questions are there,
100=5y
divide by the coefficient of y which in the case is 5
20=y
so we have total of 20 questions each are worth 5 points
now, Samuel got 9 questions wrong and if we know they are 20 total questions
20-9=11
so, we know Samuel got 11 questions correct
let's use an expression to figure out his score
let x be the number of questions
5x
substitute
5(11)=55
his score if he got x questions wrong
20-11=9

How much of an 80% salt solution must
be mixed with 50 gallons of a 13% salt
solution to obtain a solution that is
70% salt?
By means of weighted averages, we conclude that an amount of 285 gallons are needed to prepare a 70 % salt solution.
What quantities of two solutions with different concentrations are needed to obtain a new solution with a expected concentration?
In this problem we find two salt solutions with distinct concentrations, one with 80 % and another with 13 %, the latter in a quantity of 50 gallons. The required quantity of 80 % salt solution is determined by using weighted averages:
(80 / 100) · x + (13 / 100) · 50 = (70 / 100) · (x + 50)
0.8 · x + 13 / 2 = 0.7 · x + 35

Determine whether the equation below has a one solutions, no solutions, or an infinite number of solutions. Afterwards, determine two values of x that support your conclusion.
x+10=5
we conclude that the equation x + 10 = 5 has only one solution, which is x = -5
How many solutions has the given equation?Here we have the linear equation:
x + 10 = 5
In general, linear equations have only one solution, but let's solve this to see how many solutions it has.
If we subtract 10 in both sides of the linear equation, we will get:
x + 10 - 10 = 5 - 10
x = -5
So there is a single solution, which is x = -5.
