s = 6 + e
s + e = 28
We can use this system of equations to find the exact values of s and e.
We have a current value of s, so we can find the exact value of e now.
e + e + 6 = 28
Combine like terms.
2e + 6 = 28
Subtract both sides by 6.
2e = 22
Divide both sides by 2.
e = 11
Now we have an exact value of e, and can solve for the value of s.
s = 6 + 11
s = 17

The age of Sophia is 17 years and Eric is 11 years.
what is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Sophia is 6 years older than her brother eric.
The sum of their ages is 28.
let the age of Eric be x.
So, Sophia's age will be x+ 6
Then, x+ x +6 = 28
2x + 6= 28
2x= 22
x= 11
Hence, the age of Sophia is 17 years and Eric is 11 years.

Answer and explain (No its not the lower extreme etc. Its the values and the actual numbers)
There are 5 parts of a box-and-whisker plot.
Lowest Value (Minimum)= that's the left end of the graph, and shows what the minimum value is. Here, the minimum is 46.
Lower Quartile (Q₁)= This is the left edge of the "box" in a box-and-whisker plot. Here it is 55.
Median (Q₂)= This is the line in the middle of the box, and represents the very center of minimum and maximum values. Here it is 58.
Upper Quartile (Q₃)= This is the right edge of the box in a box-and-whisker plot. Here it is 63.
Highest Value (Maximum)= This is the farthest right point on your plot. Here it is 66.

The term 'lower extremes' in mathematics typically refers to the minimum value of a data set, but in this case, the student is asking for the values that represent the lower extremes.
Explanation:In mathematics, the term 'lower extremes' usually refers to the lower limit of a data set, also known as the minimum value. However, since the question specifically asks for 'values and actual numbers', we can assume that the student is referring to the values that represent the lower extremes in the data set. For example, if the data set is {3, 5, 1, 2, 7}, the lower extremes would be the values 1 and 2.

(2, 2 ), (- 2, 18 ), (0, 10 )
substitute the x-coordinate of each point into f(x) and if the value is equal to the y-coordinate then it is on the graph of f(x)
(- 18, 2 ) ⇒ y = 10 + 72= 82 ≠ 2
(- 10, 0 ) ⇔ y = 10 + 40 = 50 ≠ 0
(- 2, - 2 )⇒ y = 10 + 8 = 18 ≠ 2

jacklyn's employer matches 30% of Jacklyn's contributions to her 401(k) plan if her employer contributed $300 to the plan last year, how much did Jacklyn contribute to the plan last year?
A) $1300
B) $1000
C) $700
D) $900
B because 30% of 1000 is 300
Answer:
Option B) $1000 would be correct.
Step-by-step explanation:
Jacklyn's employer matches 30% of Jacklyn's contributions to her 401(k) plan.
Let Jacklyn's contribution = x
Her employer's contribution = 30% of x = 300
= [tex]\frac{30x}{100}[/tex] = 300
= 30x = 300 × 100
= x = 30000 ÷ 30 = $1000
Jacklyn contributed $1000 to the 401(k) plan last year.
there are 4 planets. the first planet has an orbit of 3 years. The second planet has an orbit of 5 years. The third planet has an orbit of 8 years. The fourth planet has an orbit of 12 years. if there in conjunction how long till they're in conjunction again? math problem answer
Find the LCM of the four numbers (3, 5, 8, 12)
3: 3
5: 5
8: 2 * 2 * 2
12: 2 * 2 * 3
LCM = 2 * 2 * 2 * 3 * 5
= 120
Answer: 120 years
Final answer:
The planets will be in conjunction again after 15 years.
Explanation:
To determine when the planets will be in conjunction again, we need to find the least common multiple (LCM) of their orbital periods.
The orbital periods of the four planets are: 3 years, 5 years, 8 years, and 12 years.
To find the LCM, we can list the multiples of each of the numbers and identify the smallest number that appears in each list.
The multiples of 3 are: 3, 6, 9, 12, 15, ...
The multiples of 5 are: 5, 10, 15, 20, 25, ...
The multiples of 8 are: 8, 16, 24, 32, ...
The multiples of 12 are: 12, 24, 36, ...
The smallest number that appears in all lists is 15, so the planets will be in conjunction again after 15 years.

Jackson drinks 0.44 liters of water, which was 55% of the water in the bottle. How much water was in the bottle to start?
Answer:
He had 0.8 liters to start with...
Step-by-step explanation:
0.44 is 55% of what? (what = x)
Equation: Y = P% * X
X = Y/P%
X = 0.44/55%
55% = 0.55
X = 0.44/0.55
X = 0.8
Answer:
ans is 0.8 liters
Step-by-step explanation:
Jackson drinks 0.44 liters of water, which was 55% of the water in the bottle.
Let X be the volume of water in the bottle to start.
55% of X = 0.44L
X = 0.44/55% = 0.44/55*100=44/55=4/5=0.8 liters

If f(x) = 10 + 50x, solve for x when f(x) = 310.
x = 6
given f(x) = 310, we obtain the equation

50x = 300 ( divide both sides by 50 )
x = [tex]\frac{300}{50}[/tex] = 6

if 5/8 yards of fabric costs 3.75 dollars what does one yard cost
The cost of one yard of fabric, based on given prices, is 6 dollars. This is calculated by taking the total cost and dividing by the total quantity, using the concept of ratio and proportion in mathematics.
Explanation:This problem revolves around the concept of unit rates in mathematics, especially ratio and proportion. If 5/8 yards of fabric costs 3.75 dollars, then to find the cost of one yard, known as the unit rate, we need to divide the total cost by the total quantity. Therefore, the cost of one yard would be 3.75/(5/8), which equals 6 dollars. Hence, one yard of fabric costs 6 dollars.

A bakery has 72 half gallons of milk. It takes 1 2/3 cups of milk to make the cake. Note that 1 cup= 1/8 half gallon= 0.125 half gallon. How many cakes can the bakery make? A. 43 cakesB. 288 cakesC. 345 cakesD. 576 cakes
To determine the number of cakes the bakery can make, the required milk per cake in cups is converted to half gallons and then divided into the total available milk in half gallons. Upon calculation, the bakery can make approximately 345 cakes. Thus, the correct answer to the student's question is option C) 345 cakes.
To solve how many cakes the bakery can make using 72 half gallons of milk and with each cake requiring 1 2/3 cups of milk, we must first convert the cups needed for one cake into half gallons. Since 1 cup equals 0.125 half gallons, 1 2/3 cups is equivalent to 1.6667 * 0.125 half gallons. Now, let's calculate the number of cakes:
1 2/3 cups of milk for one cake = 1.6667 * 0.125 half gallons = 0.2083 half gallons per cake.Total available milk in half gallons = 72.Number of cakes = Total available milk / Milk per cake = 72 / 0.2083.After performing the division, we find that the bakery can make approximately 345 cakes. Therefore, the correct answer is C. 345 cakes.
The area of a rectangle is 45 ft2. If the length of the long side of the rectangle is 80% greater than the short side of the rectangle, what is the length of the longer side?
To solve this problem we propose the following equation:
1) [tex]b*h =45\\[/tex] This is the equation of the area of a rectangle.
Where a and b are the sides of the rectangle
If b is the longest side, then
b is 80% longer than h.
2) [tex]b= h+0.8h\\[/tex]
Now we have 2 equations and two unknowns.
Therefore we solve the following equations
[tex]45=b*\frac{b}{1+0.8}\\[/tex]
[tex]b^2=45(1+0.8)[/tex]
[tex]b =\sqrt{45(1+0.8)}\\[/tex]
b = 9 feet
The length of the longest side is 9 feet.
The area of a rectangle is 45 ft^2
If the length of the long side of the rectangle is 80% greater than the short side of the rectangle.
Let the shortest side be the width (x)
Length of rectangle L = 80% greater than x
So length = 0.8 x + x
Length = 1.8 x
Area of the rectangle = Length * width
45 = 1.8x * x
[tex]45= 1.8x^2[/tex]
Divide by 1.8 from both sides'
[tex]25= x^2[/tex]
Take square root on both sides
x=5
so width of the rectangle = 5 feet
Length of the rectangle (longer side) = 1.8x = 1.8 * 5 = 9 feet
Put the following in slope intercept form
4x - 3y = 15
slope intercept form: y = mx + b
Note the equal sign. what you do to one side, you do to the other. First, subtract 4x from both sides
4x - 3y = 15
4x (-4x) - 3y = 15 (-4x)
-3y = -4x + 15
Next, divide -3 from both sides to isolate the y.
(-3y)/-3 = (-4x + 15)/-3
y = (4/3)x - 5
y = (4/3)x - 5 is your answer
