Answer:
7x+20
Step-by-step explanation:
To simplify you mainly just try and combine the terms
First step is to distribute the 2 that is in front of "(5+3x)"
the way you do this is multiply everything inside the parantheses by 2
(5•2+3x•2) = 10+6x
put that into the original equation and now we just have the easy part
10+6x+x+10
combine alike terms
6x+x=7x 10+10=20
7x+20 is that equation simplified
Answer:
7x+20
Step-by-step explanation:
2*5+2(3x)+x+10
10+2(3x)+x+10
10+6x+x+10
6x+x+20
7x+20

Answer: its b
Step-by-step explanation:
The system of equations x - 3y = 6; 5x - y = 10 is represented by lines m and n respectively. which is the correct option (C).
What is the slope of the line?The slope of a line is defined as the gradient of the line.
Given that line M passes through the points (-3, -3) and (6, 0).
Let the required line would be y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]
x₁ = -3, y₁ = -3
x₂ = 6, y₂ = 0
⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]
Substitute values in the equation, we get
⇒ y - (-3) = (0 - (-3))/(6-(-3) )[x -(-3))
⇒ y + 3 = 3/9(x + 3)
⇒ y + 3 = 1/3(x + 3)
⇒ 3y + 9 = (x + 3)
⇒ x - 3y = 6
Given that line N passes through the points (-3, -25) and (6, 20).
⇒ y - (-25) = (20 - (-25))/(6-(-3) )[x -(-3))
⇒ y + 25 = 45/9(x + 3)
⇒ y + 25 = 5(x + 3)
⇒ y + 25 = 5x + 15
⇒ 5x - y = 10
Therefore, the system of equations x - 3y = 6; 5x - y = 10 is represented by lines m and n respectively.

3. Candy Kane Cosmetics (CKC) produces Leslie Perfume, which requires chemicals and labor. Two production processes are available: Process 1 transforms 1 unit of labor and 2 units of chemicals into 3 oz of perfume. Process 2 transforms 2 units of labor and 3 units of chemicals into 5 oz of perfume. It costs CKC $3 to purchase a unit of labor and $2 to purchase a unit of chemicals. Each year, up to 20,000 units of labor and 35,000 units of chemicals can be purchased. Each ounce of Leslie Perfume sells for $5.
Answer:
using solver, the optimal solution is 6,666P₁ or process 1 should work for 6,666 hours during the year.
Total production = 6,666 x 3 = 19,998 ounces of perfume.
Total revenue = 19,998 x $5 = $99,990
Total costs = (6,666 x $3 per labor hour) + (6,666 x 2 x $2 per unit of chemicals) = $46,662
Operating income = $53,328
Step-by-step explanation:
Variables:
P₁ = number of hours in process 1
P₂ = number of hours in process 2
P₁ yields 3 ounces of perfume
P₂ yields 5 ounces of perfume
both are sold at $5 per ounce
15P₁ + 25P₂
labor usage:
(1P₁ + 2P₂) x $3
3P₁ + 6P₂
chemicals usage:
(2P₁ + 3P₂) x $2
4P₁ + 6P₂
Profit = 15P₁ + 25P₂ - (3P₁ + 6P₂) - (4P₁ + 6P₂) = 8P₁ + 13P₂
so we need to maximize 8P₁ + 13P₂
the constraints are:
3P₁ + 6P₂ ≤ 20,000
4P₁ + 6P₂ ≤ 35,000
P₁, P₂ ≥ 0
using solver, the optimal solution is 6,666P₁ or process 1 should work for 6,666 hours during the year.
Total production = 6,666 x 3 = 19,998 ounces of perfume.
Total revenue = 19,998 x $5 = $99,990
Total costs = (6,666 x $3 per labor hour) + (6,666 x 2 x $2 per unit of chemicals) = $46,662
Operating income = $53,328
Write an equation of the line that passes through a pair of points:
(-5,-2), (4,5)
It’s not b
Answer:
C
Step-by-step explanation:
We want to determine the equation of the line that passes through the points (-5, -2) and (4, 5).
First, let’s determine the slope of the line. We can use the slope formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let (-5, -2) be (x₁, y₁) and let (4, 5) be (x₂, y₂). Substitute appropriately:
[tex]\displaystyle m=\frac{5-(-2)}{4-(-5)}[/tex]
Evaluate:
[tex]\displaystyle m=\frac{5+2}{4+5}=\frac{7}{9}[/tex]
So, our slope is 7/9.
Now, we can use the point-slope form to determine the rest of the equation:
[tex]\displaystyle y-y_1=m(x-x_1)[/tex]
Where m is the slope and (x₁, y₁) is a point.
So, we will substitute 7/9 for m.
For consistency, we will also let (x₁, y₁) be (-5, -2). Hence:
[tex]\displaystyle y-(-2)=\frac{7}{9}(x-(-5))[/tex]
Simplify:
[tex]\displaystyle y+2=\frac{7}{9}(x+5})[/tex]
Distribute:
[tex]\displaystyle y+2=\frac{7}{9}x+\frac{35}{9}[/tex]
Subtract 2 from both sides. Note that 2 is equivalent to 18/9. Hence:
[tex]\displaystyle y=\frac{7}{9}x+\frac{35}{9}-\frac{18}{9}[/tex]
Simplify:
[tex]\displaystyle y=\frac{7}{9}x+\frac{17}{9}[/tex]
Therefore, our answer is C.

Answer:
x = - 10.5
Step-by-step explanation:
Given that y is inversely proportional to x² then the equation relating them is
y = [tex]\frac{k}{x^2}[/tex] ← k is the constant of proportion
To find k use the condition y = 8 when x = 3.5 , then
8 = [tex]\frac{k}{3.5^2}[/tex] ( multiply both sides by 3.5²
8 × 3.5² = k , that is
k = 98
y = [tex]\frac{98}{x^2}[/tex] ← equation of proportion
When y = [tex]\frac{8}{9}[/tex] , then
[tex]\frac{8}{9}[/tex] = [tex]\frac{98}{x^2}[/tex] ( cross- multiply )
8x² = 882 ( divide both sides by 8 )
x² = 110.25 ( take the square root of both sides )
x = ± [tex]\sqrt{110.25}[/tex] = ± 10.5
Thus x = - 10.5 ← is the negative value of x

Step-by-step explanation:
Remember that it doesn't matter how many numbers are after the tenths place of a decimal point what matters is the tenths place itself. If you have a decimal that has dozens of numbers but it's tenth place is a 3 and then you have a decimal with 5 numbers in whole but it's tenths place is 4, the 4 is greater then the 3 simply because it's greater in tenths.

The solution of an inequality in terms of n that represents all numbers of people who can go on the tour to make it profitable would be 58.
What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.
Given that company for large groups charges a one time fee of $200 plus an additional $25 per person who goes on the tour.
Let's consider n be the number of people going on the tour.
Then the inequality in terms of n that represents all numbers of people who can go on the tour to make it profitable would be;
200+25n ≥1650
To solve for n;
200+25n=1650
25n=1450
n=58

Jessie cuts grass on the weekends. If they get paid $20 a yard and made a total
of $100 last weekend, which algebraic equation can be solved to find how many
yard they cut last weekend? (Let X be the number of yards they cut)

Marcus has been running a beverage cart on weekends at the beach, selling water and soda. Last Saturday, he sold 40 bottles of water and 25 sodas, bringing in $110. Sunday, he sold 50 bottles of water and 45 sodas, making $165. What are the prices for each beverage option?
Answer:
$2 for soda and $1.5 for a bottle of water
Step-by-step explanation:
You start by turning both situations into an equation
Let x represent bottles of water and y represent sodas
Saturday:
[tex]40x+25y=110[/tex]
Sunday:
[tex]50x+45y=165[/tex]
You then want to start by cancelling out the x in this equation, to do that you want 40x to become -50x so you:
50÷40=1.25
You then times the whole equation by -1.25
40x+25y=110
×-1.25
-50x+-31.25y= -137.5
You then add this equation by Sunday's equation
50x+45y=165
-50x+-31.25y=-137.5
13.75y=27.5
You now want to make the co-efficient of y a whole number (for example 15) so you divide 15/13.75=1.09 recurring
13.75y=27.5
×1.09 recurring
15y=30
15y/15=30/15
y=2
Now that we know y = 2
We can use either Saturday or Sunday's equation to figure out the value of [tex]x[/tex]
Let's use Sunday's:
50x+45×2=165
50x+90=165
50x+90-90=165-90
50x/50=75/50
x=1.5
Let's check our answer with Saturday's equation
40×1.5+25×2=110
This equation is correct
Therefore the prices for each beverage option is $1.5 for a bottle of water and $2 for a soda
