Write a description of the set,  {7, 8, 9, 10, ..} is:

All natural numbers greater than 6

Option A is correct

The given set is:

{7, 8, 9, 10, .........}

Natural numbers are counting numbers. They are positive integers

Rational numbers are numbers that can be written as ratio of two integers

The set shown is an infinite set. The beginning is 7 but the end is not included.

7, 8, 9, are natural numbers

Not all rational numbers are natural numbers are rational numbers

Therefore, the set contains all natural numbers greater than 6

 8 /4 = 2

answer: each apple cost 2$

Answer:

$4.50.

Step-by-step explanation: Since the market is selling 8 apples for $4, we can determine that one apple is 50 cents. Knowing that information, we can apply that same rule to 9 apples, resulting in a total of $4.50. Hope this answered your question.

Answer:

The equations of the line are

y + 7 = [tex]\frac{9}{7}[/tex] (x + 4) ⇒ B

y - 2 = [tex]\frac{9}{7}[/tex] (x - 3) ⇒ E

Step-by-step explanation:

The point-slope form of the linear equation is

[tex]y-y1=m(x-x1)[/tex] , where

∵ The line passes through points (-4, -7) and (3, 2)

∴ x1 = -4 and y1 = -7

∴ x2 = 3 and y2 = 2

→ Use the rule of the slope above to find it

∵ [tex]m=\frac{2--7}{3--4}=\frac{2+7}{3+4}=\frac{9}{7}[/tex]

∴ The slope of the line is [tex]\frac{9}{7}[/tex]

→ Substitute the values of m and (x1, y1) in the form of the equation above

∵ y - -7 = [tex]\frac{9}{7}[/tex] (x - -4)

∴ y + 7 = [tex]\frac{9}{7}[/tex] (x + 4)

∴ The equation of the line is y + 7 = [tex]\frac{9}{7}[/tex] (x + 4)

→ Substitute the values of m and (x2, y2) in the form of the equation above

∵ y - 2 = [tex]\frac{9}{7}[/tex] (x - 3)

∴ The equation of the line is y - 2 = [tex]\frac{9}{7}[/tex] (x - 3)

→  Look at the answers to find the same equations

∴ Answers B and E have the same equations

Answer:

1/8 tablespoons

Step-by-step explanation:

Since the child needs to take 1/2 tablespoons off medicine per day in 4 equal doses, you will divide the 1/2 tablespoons into 4 equal doses, so you need to divide by 4.

You can do this by multiplying 1/2 by 1/4.

Step-by-step explanation:

because the a gets you a 39900% , and c gets you a 500%, and d gets you a 300%. So b is the only option that makes sense.

Step-by-step explanation:

Answer:

a) [tex]p \geq 60\,ft^{2}[/tex], b) [tex]w \geq 36\,ft[/tex], c) [tex]1\,qt \leq q \leq 2\,qt[/tex], d) [tex]0.70\cdot p + 0.10\cdot w + 8\cdot q \leq 65[/tex]

Step-by-step explanation:

In this question we proceed to translate each sentence into mathematical language and, more specifically, inequations:

a) At least 60 square feet of plywood for the surface

Let [tex]p[/tex] the surface area of plywood, measured in square feet, and the inequation is:

[tex]p \geq 60\,ft^{2}[/tex] (Eq. 1)

b) At least 36 feet of wood planks for the frame of the dog house

Let [tex]w[/tex] the total length of wood planks, measured in feet, and the inequation is:

[tex]w \geq 36\,ft[/tex] (Eq. 2)

c) Between 1 and 2 quarts of paint

Let [tex]q[/tex] the total capacity of paint, measured in quarts, and the inequation is:

[tex]1\,qt \leq q \leq 2\,qt[/tex] (Eq. 3)

d) Han's budget is $ 65. Plywood costs $ 0.70 per square foot, planks of wood cost $ 0.10 per foot and paint costs $ 8 per quart.

Dimensionally speaking, we understand that cost equals unit cost multiplied by physical variable (i.e. Area, length or capacity). Let [tex]p[/tex], [tex]w[/tex] and [tex]q[/tex] the surface area of plywood, the total length of wood planks and the total capacity of paint, respectively. The sentence is represented by the following inequation:

[tex]0.70\cdot p + 0.10\cdot w + 8\cdot q \leq 65[/tex] (Eq. 4)

Write an inequality to represent each constraint(material and cost)

Plywood:

plywood ≥ 60 square feet

Planks:

planks ≥ 36 feet

Paints

1 quarts ≤ paints ≤ 2 quarts

Inequality to represent cost constraint

Plywood = $0.70

planks of wood = $0.10

paint costs $8

Total cost = $65

0.70 × p + 0.10 × pw + 8 × Pa ≤ 65

0.70p + 0.10pw + 8pa ≤ 65

Answer:

(7, 9)

Step-by-step explanation: To solve this system, I would use addition.

To solve a system of equations by addition,

we need one of our variables to cancel out.

Notice that we have a 4x in our first equation.

If we had a -4x in our second equation, the x's would cancel.

To create a -4x in the second equation,

we must multiply the entire equation by -4.

So we have (-4)(x + 6y) = (61)(-4).

Rewriting this equation, we have -4x - 24y = -244.

Now let's rewrite both equations.

4x - 5y = -17

-4x - 24y = -244

_____________

Now when we add the equations together, the x's cancel.

So we're left with -29y = -261.

Now divide both sides by -29 and we have y = 9.

To find x, we plug a y back in for x in either equation.

So let's go with our second equation, x + 6y = 61.

Plugging a 9 in for y, we have x + 6(9) = 61 or x + 54 = 61.

Subtracting 54 from both sides, we have x = 7.

So x = 7 and y = 9 which we can write as the ordered pair (7, 9).

Step-by-step explanation:

So in case you did not know, MNJ and KNL have the same angle measure, so to find x you would just set each of the eqautions equal to each other. distribute the 3 to (x + 14) and get 5x+  2 = 3x + 42. subtract 2 from one side and do the same on the other side. this would leave your eqaution looking like this: 5x-40= 3x, next subtract 5x from both sides and you will get  -2x=-40, then vide by -2 and x will equal 20

Given the question :

A shop sells matching hats and scarves. The scarves cost 1.5 times as much as the hats. Write 2 patterns that could represent the cost of 1,2,3,4,and5 hats and scarves list the first 5 terms of each pattern then write the cost of 6 hats and scarves using the patterns you wrote

Let cost of hats = h

Cost of scarves (s) = 1.5h

Hence of hat = $4 ; Scarve = 1.5 * 4 = 6

___________1__2___3___4___5

Cost of hat__ 4__8___12__16__20

Scarve cost__6__12__18__24__30

cost price * quantity sold

Cost of hat = 6 * $4 = $24

Cost of 6 Scarve = 6 * $6 = $36

Step-by-step explanation:

check answer:

23 + 24 + 25 = 72

Answer:

Step-by-step explanation:

#1

so 1st integer=35 and 1st integer=31

x=4+y

x+y=66

4+2y=66

2y=62

y=31

x=4+31

x=35

#2

1st integer = x 2nd integer = x - 8

(x) + (x - 8) = 50

x + x - 8 = 50

2x - 8 = 50

2x = 58

x= 29

so 1st integer = x = 29

and 2nd integer = x - 8 = 29 - 8 = 21
