Answer:
B. 3m^6 - 3m^3 - 2m^2
Step-by-step explanation:
Step 1: (6m^8 - 6m^5 - 4m^4)/2m^2
Step 2: (6m^8/2m^2) + (-6m^5/2m^2) + (-4m^4/2m^2)
Step 3: 3m^6 - 3m^3 - 2m^2
1) Given equation
2) You can imagine this fraction as (6m^8 - 6m^5 - 4m^4) multiplied by 1/(2m^2), so you can think of it like multiplying a monomial by a trinomial where you multiply the monomial by each term. In this step you multiply 1/(2m^2) by each of the terms in the trinomial.
3) In this step, you divide the terms in the parenthesis. You first divide the constants (ex: 6÷2=3 in (6m^8/2m^2)), and then you divide the variable exponents (ex: m^8÷m^2=m^6 in (6m^8/2m^2)).
A restaurant charges $5.00 for a slice of pizza that is 1/3 of a pizza and $4.50 for a slice that is 1/5 of a pizza. One day they cooked 8 pizzas that were all the same size. If they sell all the slices, would they make more money by slicing each pizza into thirds or fifths? How much more? Explain.
Answer:
5thsStep-by-step explanation:
Given that:
Price of whole pizza (A) = 5 × 3 = $15Price of whole pizza (B) = 4.50 × 5 = $22.50They make 8 whole pizzas.
Therefore
Thirds (A) = 15 × 8 = $120Fifths (B) = 22.50 × 8 = $180They'll make more money if they slice it into fifths.
180 - 120 = $60
Because if they slice it into thirds, total profit will be $60 less

A construction company ordered 85 wood beams for a new project. Each beam
was 25.5 ft long. What was the total length of all of the beams put together?
Write your answer in yards.
Use the table of conversion facts as necessary, and do not round your answer.
Answer: 722.5 yards
Step-by-step explanation:
85 x 25.5 = 2167.5 feet for 85 wood beams.
Convert 2167.5 feet to yards.
There are 3 feet in 1 yard; so divide 2167.5/3 which equals 722.5 yards
What is the solution to this inequality? x/10+6 ≥ 8
A. x ≥ 74
B. x ≤ 20
C. x ≥ 20
D. x ≤ 74
The solution of the inequality is x ≥ 20
What is an inequality?An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value.
Given is an inequality, x/10+6 ≥ 8
Rules for manipulating inequalities
Rule 1.) Adding or subtracting the same quantity from both sides of an inequality leaves the inequality symbol unchanged.
Rule 2.) Multiplying or dividing both sides by a positive number leaves the inequality symbol unchanged.
Solving,
x/10+6 ≥ 8
x/10+6-6 ≥ 8-6
x/10 ≥ 2
10×x/10 ≥ 2×10
x ≥ 20
Hence, The solution of the inequality is x ≥ 20

Find the missing side i the problem using special right triangle. Can you help me
Answer:
x = 13.86
y = 6.93
Step-by-step explanation:
tan 30° = y/12
0.5774 = y/12
y = 12(0.5774) = 6.93
cos 30° = 12/x
0.8660 = 12/x
x = 13.86

One angle of an isosceles triangle measures 130°. Which other angles could be in that isosceles triangle? Choose all that apply
50, 45, 130, 25
In ΔIJK, i = 850 inches, j = 250 inches and ∠K=80°. Find the length of k, to the nearest inch.
Answer:
886 inches
Step-by-step explanation:
Because we know the length for sides I and J, we can use the pythagorean theorem to get K. 850^2 + 250^2=KY^2. 850^2 = 722,500, and 250^2 = 62,500. 722,500 + 62,500 = 785,000. 785,000 to the square root rounded to the nearest inch is 886 inches.

Answer:
I solved with substitution since you weren't specific on how to answer it but I got ( 2,3 )
[x = 2 , y = 3]
Answer:
x=2
y=3
Step-by-step explanation:
[tex]\left \{{4x+3y=17{} \atop{5x-2y=4}} \right.[/tex]
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
4x+3y=17,5x−2y=4
To make 4x and 5x equal, multiply all terms on each side of the first equation by 5 and all terms on each side of the second by 4.
5×4x+5×3y=5×17,4×5x+4(−2)y=4×4
Simplify.
20x+15y=85,20x−8y=16
Subtract 20x−8y=16 from 20x+15y=85 by subtracting like terms on each side of the equal sign.
20x−20x+15y+8y=85−16
Add 20x to −20x. Terms 20x and −20x cancel out, leaving an equation with only one variable that can be solved.
15y+8y=85−16
Add 15y to 8y.
23y=85−16
Add 85 to −16.
23y=69
Divide both sides by 23.
y=3
Substitute 3 for y in 5x−2y=4. Because the resulting equation contains only one variable, you can solve for x directly.
5x−2×3=4
Multiply −2 times 3.
5x−6=4
Add 6 to both sides of the equation.
5x=10
Divide both sides by 5.
x=2
The system is now solved.
x=2,y=3
