Answer:

4 >x

Step-by-step explanation:

3(x + 6) – 2(x – 4) > 5(x + 2)

Distribute

3x+18 -2x+8 > 5x+10

Combine like terms

x +26 > 5x+10

Subtract x from each side

x+26-x > 5x-x+10

26 > 4x+10

Subtract 10 from each side

26-10 >4x+10-10

16 >4x

Divide each side by 4

16/4 >4x/4

4 >x

Answer: [tex]\frac{2A}{h} = w[/tex]

Step-by-step explanation:

The formula for area of a triangle is [tex]A = wh\frac{1}{2}[/tex]

Now we have to isolate for w.

First multiply by the 2 which is the reciprocal of 1/2 to cancel it out.

[tex]2A = wh\\[/tex]

Now divide by h to isolate w.

[tex]\frac{2A}{h} = w[/tex]

The length of crimson velvet bolt which Malik's shop has left is 1680 centimeters.

Recall :

1 meter = 100 centimeters

Original Length of Bolt = 32 meters = (32 × 100) = 3200 centimeters

Total length of bolt purchased :

Morning purchase = 120 centimeters

Additional purchase = 14 meters = (14 × 100) = 1400 centimeters

Total length purchased = (120 + 1400) = 1520 centimeters

The length of crimson velvet bolt left :

(Original length - total length purchased)

(3200 - 1520) centimeters = 1680 centimeters

Hence, Malik's shop has 1680 centimeters of Crimson velvet bolt left

Step-by-step explanation: It's just basic prealgebra!

Answer:

[tex]f(x) = -2(x - 4)^2 -3[/tex]

Vertex = (4, -3)

Graph in the image attached, additional points:

(2, -11), (3, -5), (5, -5), (6, -11)

Step-by-step explanation:

The vertex of f(x) can be found using the formula:

[tex]x_{vertex} = -b/2a[/tex]

[tex]x_{vertex} = -16 / (-4)[/tex]

[tex]x_{vertex} = 4[/tex]

to find y_vertex, we use x_vertex in f(x):

[tex]f(x_{vertex}) = -2 * 4^2 + 16*4 - 35[/tex]

[tex]f(x_{vertex}) = -3[/tex]

So the vertex is (4, -3)

To write the function in the form [tex]f(x)=a(x-h)^2+k[/tex], we just need to calculate h = -b/2a and then find k:

[tex]h = -b/2a = -16/(-4) = 4[/tex]

[tex]f(x) = -2(x - 4)^2 + k = -2(x^2 - 8x + 16) + k = -2x^2 + 16x - 32 + k[/tex]

Comparing both forms of f(x), we have:

[tex]-32 + k = -35[/tex]

[tex]k = -3[/tex]

So we have:

[tex]f(x) = -2(x - 4)^2 -3[/tex]

Now let's find the four additional points.

Two points to the left: x = 3 and x = 2

[tex]f(3) = -2 * 3^2 + 16*3 - 35 = -5[/tex]

[tex]f(2) = -2 * 2^2 + 16*2 - 35 = -11[/tex]

Two points to the right: x = 5 and x = 6

[tex]f(5) = -2 * 5^2 + 16*5 - 35 = -5[/tex]

[tex]f(6) = -2 * 6^2 + 16*6 - 35 = -11[/tex]

The solution is: x = 10/3 hours

What is the equations with one variable?

An equation with one variable is a mathematical statement that involves an unknown quantity represented by a letter, usually x, and an equal sign, where the expressions on both sides of the equal sign have the same value.

We need to set up an equation using the given information to solve for x.

Let's start with Dwayne's formula:

Cost = 30x + 50

And Ivor's formula:

Cost = 45x

Since a job of x hours costs the same for both Dwayne and Ivor, we can set their formulas equal to each other:

30x + 50 = 45x

Simplifying and solving for x:

50 = 15x

x = 50/15

x = 10/3 hours

Therefore, the solution is: x = 10/3 hours

Answer:

32 chairs

Step-by-step explanation:

In the soft Boulder cafe they a chairs , table and customers and the 3 members staffs.

Each Table = 3 legs

Each Chairs = 4 legs

Each customer  = 2 legs

Each members of staffs = 2 legs

4 chairs goes with each table. This means 4 × 4 = 16 legs of chairs for each 3 legs of table.

At a certain time 3/4 of the chairs are occupied by customers. That is 3 out of 4 chairs are occupied plus 6 tables . Therefore,

3 + 16 + 6 = 25 legs of table

206 legs altogether - the 6 legs of the staff(3 staffs has 6 legs)= 200 legs

This means 200 legs = 8 tables. Therefore,

8 tables requires 32 chairs

Answer:

Option 2: 5x - 3y = 30

Step-by-step explanation:

Step 1: Find slope

(0-(-5))/(6-3) = 5/3

Step 2: Find b

y = 5/3x + b

0 = 5/3(6) + b

b = -10

Step 3: Write in slope-intercept form

y = 5/3x - 10

Step 4: Move x over

-5/3x + y = -10

Step 5: Multiply by -3 on both sides

5x - 3y = 30

And we have our final answer!

Answer:

Step-by-step explanation:

Ok so the mean is the average of all the data. So we add up all the numbers, then divide that by the quantity of numbers.

For week one, thats 48,52,52,53,60,63,65 which equals 393, then we divide that by 7, and get 56.142857142857, so we round that to 56.1

Week 2 is 54,55,56,59,60,62,63 which is 409 divided by 7, and thats 58.428571428571 rounded is 58.4

Next up is the MAD (mean absolute deviation) thats the average distance between each value and the mean.

Week 1 MAD: 5.5918367346939 5.5

Week 2 MAD: 2.9387755102041 2.9

SHE CANNOT pls mark brainleist

Step-by-step explanation:

If you use the Triangle Inequality Theorem, you will find that 4+10 equals 14, which is less than 16. It has to be greater than 16 to be a triangle.

Sarkis cannot draw a triangle with these side lengths. Therefore, option A is correct.

Given that, a triangle with sides measuring 4 ft, 10 ft, and 16 ft.

In the triangle, the sum of any two sides is always greater than the third side. The difference between any two sides of the triangle is always less than the third side.

Sarkis cannot draw a triangle with these side lengths. Therefore, option A is correct.

So, let's start off with h

The expression needs to be '3 more than h'

This can be written as:

h + 3

The expression also needs to be 'five times' this value

This can be written as:

5(h + 3)

That would be your answer ^^
