Step-by-step explanation:

Just took the quiz

Answer:

C

Step-by-step explanation:

On the left, we have 3 positive x bars and 8 1s.

Hence, the left can be represented by the following expression:

[tex]3x+8[/tex]

On the right, we have 4 positive x bars and 6 1s.

Hence, the right can be represented by the following expression:

[tex]4x+6[/tex]

The two are equivalent. Therefore:

[tex]3x+8=4x+6[/tex]

Solve for x. Subtract 6 from both sides:

[tex]3x+2=4x[/tex]

Subtract 3x from both sides:

[tex]2=x[/tex]

Flip:

[tex]x=2[/tex]

Hence, our answer is C.

Answer:

164 tiles

Step-by-step explanation:

Per the above details, we will require tiles along all the sides of the swimming pool ,hence the circumference of the pool is denoted as;

= 2(wide + long)

Wide = 30 feet

Long = 50 feet

Circumference = 2(30 + 50)

Circumference = 2(80)

Circumference = 160.

It means that minimum of 160 tiles of 1 ft length is required, however, we will also require tile on each of the corners(4), total equals

= 160 + 4

= 164 tiles

A total of 164 tiles are there surrounding the pool.

Hope this helps! Have a nice day :D

Since we don't have a total cost we will write an equation that will allow us to find the cost of x. The equation is 4x= 2x + $3 + $3.75 + $2.75. Now that we have our equation we are going to start by adding 3, 3.75, and 2.75. When added together, they come out with a total of 9.5. Now the equation becomes 4x= 2x + $9.50. Since we have our new equation we are going to subtract 2x from both sides of the equation. We now have the equation 2x= $9.50. Finally, you will divide both sides by 2. This leaves us with the final outcome x= $4.75. This means that one glues stick cost $4.75. Let's check by substituting $4.75 as the value of x in the expressions 4x is Carlo's total and 2x + $3 + $3.75 + $2.75 is Helen's total. First we do 4x, 4 multiplied by 4.75 equals 19, so Carlo spent $19 on art supplies. Now we do 2x + $3 + $3.75 + $2.75, which is 9.5 added to 9.5 and equals 19. So Helen spent $19 on art supplies. This proves that the cost of one glue stick, x, is equal $4.75.

Answer:

D; it was bought for $5,487.36

Step-by-step explanation:

Let the investment amount be $x

We use the formula for simple interest to get the interest

(2112.64-x) = (x * 5.5 * 7)/100

211264-100x = 38.5x

138.5x = 211264

x = 211264/138.5

x = 5,847.36

Answer:

Number of moles = 41.67 (Approx)

Number of carbon atom = 250.97 x 10²³ (Approx)

Step-by-step explanation:

Given:

Amount of carbon = 500 g

Find:

Number of moles

Number of carbon atom

Computation:

Number of moles = 500 / Atomic number of weight

Number of moles = 500 / 12

Number of moles = 41.67 (Approx)

Number of carbon atom = Number of moles x Avogadro number

Number of carbon atom = 41.67 x 6.023 x 10²³

Number of carbon atom = 250.97 x 10²³ (Approx)

Answer:

Step-by-step explanation:

Are there any choices?

2(4x+1)

8x+2

The expression equivalent of 2(4x+1)​ would be; 8x+2

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.

To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.

We need to find the expression into an equivalent.

Therefore, given expression is

2(4x+1)​

This expression could also be given by;

2(4x+1)​ = 2(4x ) + 2

Now, we know that:

2(4x+1)​ = 8x+2

Hence, the expression equivalent of 2(4x+1)​ would be; 8x+2

3 cans = 6.90

1 can= 6.90/3

1 can = $2.3

Therefore the cost of 10 cans can be calculated as follows

1 can= $2.3

10 cans= 10×2.3

= $23

Hence 10 cans will cost $23

Answer:

The constant of proportionality is 0.54

Step-by-step explanation:

Given:

P = 0.54n

Where,

P = price of pears

n = number of pears

What is the constant of proportionality (unit rate)?

The constant of proportionality is 0.54

This means a unit of pears cost $0.54

If the number of pears bought, n = 50

Then,

P = 0.54n

When n = 50

P = 0.54(50)

= 27

P = 27 when n = 50

The correct answer is:

The constant of proportionality is 0.54

The image of (-3, -3) after dilation by a scale factor of 1/3 centered at the origin is  (-1, -1).

Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.

Dilation: The preimage is scaled up or down to create the image.

Reflection: The picture is a preimage that has been reversed.

Rotation: Around a given point, the preimage is rotated to create the final image.

Translation: The image is translated and moved a fixed amount from the preimage.

Given, the image of (-3, -3) after dilation by a scale factor of 1/3 centered at the origin will be,

= (-3/3, -3/3).

= (-1, -1).
