a) Use a percent equation OR set up a proportion that will use to solve the problem.

b) Solve the problem. Show your work.

Answer:

False, False, True, False

Step-by-step explanation:

The correct statements are:

(2x+y) is a factor of the expression 3(2x+y).

(2x+y) is a sum of two terms.

a) 2x is a factor of the expression (2x+y): False.

2x is not a factor of (2x+y) because it doesn't divide evenly into it.

b) (2x+y) is a factor of the expression 3(2x+y): True.

(2x+y) is a factor of 3(2x+y) because it divides evenly into it.

c) (2x+y) is a sum of two terms: True.

(2x+y) is a sum of the two terms 2x and y.

d) 3(2x+y) is a product of two terms: False.

3(2x+y) is a product of three terms: 3, 2x, and y.

Hence the b and c are the correct statements.

Answer:

15-1=14

48-34=14

Step-by-step explanation:

To check work

The next three numbers in sequence are 22, 32 and 44

Solution:

Given sequence is:

2, 4, 8, 14, ...

We have to find the next 3 numbers in sequence

Let us understand the logic used in this sequence

[tex]First\ term = 1^2 -1+2 = 1 + 1 = 2\\\\Second\ term = 2^2 -2 + 2 = 4\\\\Third\ term = 3^2 - 3 + 2 = 9 - 1 = 8\\\\Fourth\ term = 4^2 -4 + 2 = 16-2 = 14[/tex]

Thus the formula used is:

[tex]a_n = n^2 - n +2[/tex]

Where, "n" is the location of term in sequence

To find the next three terms:

[tex]Fifth\ term = 5^2 - 5 + 2 = 25 - 3 = 22\\\\Sixth\ term = 6^2 - 6 + 2 = 36 - 4 = 32\\\\Seventh\ term = 7^2 -7 + 2 = 49 - 5 = 44[/tex]

Thus the next three numbers in sequence are 22, 32 and 44

Answer:

(a) 3 inches

(b) Her scale model drawing WILL fit on the piece of paper 8.5 by 7 inches

Step-by-step explanation:

Scaling

We use scales to represent realities in reduced spaces. In the case of lengths or surfaces, the scale allows us to draw the shapes in normal sheets of paper.  

(a)

Kelly's rock garden has a length of 6 feet. She uses a 1 inch:2 feet scale. this means that the model length is

6 feet*1 inch/2 feet = 3 inches

(b)

The width of the model is 5 inches, keeping the same scale it means the real length is

5 inches * 2 feet / 1 inch = 10 feet

The model will have 3 inches by 5 inches, it perfectly fits on any regular piece of paper

Answer:

0.2  (compression)

Step-by-step explanation:

Given

Length of paper = 11 inches,

Width of paper = 8 1/2 = 17/2 inches

Length of logo = 2 1/5 = 11/5 inches

Width of logo = 1 7/10 = 17/10 inches

Scale factor based on Length

=Length of Logo ÷ Length of paper

= 11/5 ÷ 11

= 0.2  (since it is less than 1, this is a compression)

(Sanity Check: Check width scale factor = length scale factor)

Scale factor based on width

=Width of Logo ÷ Width of paper

= 16/10 ÷ 17/2

= 0.2  (this is the same as the length scale factor so this checks out ok!)

Answer:

the answer is savings (d).

Step-by-step explanation:

I had a test and this helped a LOT so now I can help you,

hope it helped.

If you are not prepared for an emergency, the most likely missing element from your financial plan is savings.

Setting and accomplishing financial objectives through the process of developing a plan to control income, spending, and investments is known as financial planning. Financial planning is to assist people and families in achieving independence, stability, and security in their financial lives.

In conclusion, financial planning is a thorough process that includes establishing financial objectives, assessing your present financial condition, creating a budget and savings plan, controlling debt and risk, and routinely reviewing and modifying your plan. Individuals and families may attain financial security and stability by following these steps as they work towards their long-term financial objectives.

Given data ,

Savings are most likely the component of your financial plan that is lacking if you are not ready for an emergency.

Each financial plan must include savings since they provide as a safety net in the event of crises like unanticipated medical costs, auto repairs, or job loss. Lack of funds may compel you to rely on high-interest loans or credit cards, which might result in long-term financial issues.

While having funds to cover unexpected costs should be a key concern, a financial plan should also include a budget, investments, and financing.

An expression that is equivalent to [tex](12x^4-4x^3+7x+6)+(3x^2-4x+14)[/tex] include the following: D. [tex]12x^4-4x^3+3x^2+3x+20[/tex]

In Mathematics and Euclidean Geometry, the degree of a polynomial function is the highest power among each of its term.

The leading coefficient represents the coefficient of the leading term while the leading term is the term with the highest degree. Also, a constant polynomial is a polynomial that has only a constant term and no variable.

In this exercise and scenario, your are required to add the polynomial functions together.

First of all, we would rearrange the polynomial functions by collecting like terms and then add them together as follows;

[tex]12x^4-4x^3+3x^2-4x+7x+6+14\\\\12x^4-4x^3+3x^2+3x+20[/tex]

Complete Question:

C  [tex]15x^6-4x^3+3x+20[/tex]

D [tex]12x^4-4x^3+3x^2+3x+20[/tex]

Final answer:

To find the equivalent expression, add like terms from both expressions, resulting in 12x⁴ - 4x³ + 3x² + 3x + 20.

Explanation:

To find the expression equivalent to (12x⁴-4x³+7x+6)+(3x²-4x+14), we simply add the like terms from both expressions.

Firstly, observe that there are no other terms with the same degree as 12x⁴ and -4x³, so they will remain as they are.

Next, add the coefficients of the x terms and the constants: 7x + (-4x) = 3x and 6 + 14 = 20.

However, there's a 3x² term in the second expression which doesn't have a matching term in the first expression, so it also remains unchanged.

Combining all these, the equivalent expression is 12x⁴ - 4x³ + 3x² + 3x + 20.

Step-by-step explanation:

6 meters of fabric = 10.35

divide 3.45 by 2

1.72

add 1.72+10.35

10.07$

Answer:

Set up a proportion 2m/$3.45 = 7m/x

then cross multiply

7(3.45)=2x

then divide both sides by 2

x=12.075 which is roughly $12.08

Answer:

Therefore d = 100 is a solution of the given equation.

A question that solving this problem could answer is "what is the range of d"

d < 171.43

Step-by-step explanation:

i) the given equation is 10 - 0.035d > 4

ii) if d = 100 then 10 - (0.035[tex]\times[/tex] 100) = 10 - 3.5 = 6.5 > 4

Therefore d = 100 is a solution of the given equation.

A question that solving this problem could answer is "what is the range of d"

10 - 0.035d > 4

therefore -0.035d > 4 - 10

therefore -0.035d > -6

therefore 0.0035d < 6

therefore d < 6 / 0.035 [tex]\Rightarrow[/tex] d < 171.43

Final answer:

100 is a solution to the inequality 10 - 0.035d > 4 because, after substituting d with 100, the inequality 6.5 > 4 holds true.

Explanation:

To determine whether 100 is a solution of the inequality 10 - 0.035d > 4, we substitute d with 100 and check if the inequality holds true:

10 - 0.035(100) > 4

10 - 3.5 > 4

6.5 > 4

Since 6.5 is indeed greater than 4, we can confirm that 100 is a solution to the inequality.

A corresponding question this problem could answer might be: "If a part-time employee loses $0.035 from their savings for each day they work, after how many days will their savings be reduced to less than $4 if they initially had $10?" Solving the inequality would help find the maximum number of days the employee can work before their savings fall below $4.

Answer:

11 boys 8 girls

Step-by-step explanation:

There are 19 total students.

There are 3 more boys than girls

girls + 3 = boys ( because there are three more boys)

boys + girls = 19

You can substitute g +3 for b so:

2 girls +3 = 19

19 - 3 = 16

16/2 = girls

8 = girls

Once you find g just subtract the amount of girls from 19 to get the amount of boys.

19 kids - 8 girls = 11 boys

Option D is correct.

Option A: [tex]C(x)=1,200+120 x R(x)=200 x[/tex] is the equation.

Explanation:

Let x represents the number of hours per month the store is open.

It is given that the the monthly rent(expense) = $1200

Also, the employee salary for each hour(expense) = $120x

Thus, the total expense C(x) is [tex]1200+120x[/tex]

It is also given that the income per hour(revenue) is $200x

Thus, the revenue function R(x) is [tex]200x[/tex]

The break - even point is given by

Total expense = Revenue

Thus, [tex]C(x)=1,200+120 x R(x)=200 x[/tex] is the equation.

Hence, Option A is the correct answer.
