Simplify the expression 6s + 9c - 2s

Answer:

10.07$

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:

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:

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.

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:

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 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.

a. The inequality 15x+300≤750 represents the situation.

b. It means that the band can spend at most $30 on each uniform without exceeding the budget.

Step-by-step explanation:

Given,

Budget = $750

Competition fee = $300

Uniforms to make = 15

Let,

x be the amount for each uniform.

a.  Write an inequality to represent this situation.

Uniforms to make * Cost per uniform + Competition ≤ Budget

15x+300 ≤ 750

The inequality 15x+300≤750 represents the situation.

b.  Solve the inequality and describe what it means in the situation.

[tex]15x+300\leq 750\\15x+300-300\leq 750-300\\15x\leq 450[/tex]

Dividing both sides by 15

[tex]\frac{15x}{15}\leq \frac{450}{15}\\x\leq 30[/tex]

It means that the band can spend at most $30 on each uniform without exceeding the budget.

The inequality representing this situation is 15x + $300 <= $750. Solving for x gives x <= $30

The student is interested in determining how much the school marching band can spend on each new uniform given a specific budget constraint. To represent this situation, we need to establish an inequality.

Writing the inequality-
Let's denote the cost of one uniform as x. With 15 uniforms needed and competition fees totalling $300, the inequality that represents the budget situation is:

15x + $300 <= $750

Solving the inequality-

To solve for x, subtract $300 from both sides of the inequality:

15x <= $450

Next, divide both sides by 15:

x \<= $30

This means that they can spend at most $30 for each uniform. The inequality tells us the maximum spending cap for one uniform, ensuring the total cost for all uniforms plus competition fees does not exceed the available budget of $750.

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;

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.

Answer:

Length = 45

Width = 38

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.
