Match each table showing a proportional relationship between x and y with its constant of proportionality.

Answer:

708480

Step-by-step explanation:

You follow the order of BEDMAS. There are brackets in this equation, meaning we have to focus on what is inside the brackets first. The next step is Exponents. So you multiply 2.05 by 10^5.

This would give you 205000.

You then multiply this number by the number on the outside of the brackets which is 3.456.

This would give you 708480. (You can get these answers by using a calculator).

Don't forgot to follow the order of BEDMAS or whatever law of operations you were taught (BIDMAS/BIMDAS etc)

Answer:

x = - 26

Step-by-step explanation:

Let the number be x.

According to the question,

[tex]\frac{x+5}{x-2} = \frac{3}{4}\\[/tex]

Cross multiplying 4 & 3 gives :-

[tex]4(x+5)=3(x-2)[/tex]

And solving this eqn. gives :-

[tex]4(x+5)=3(x-2)\\=> 4x+20=3x-6\\=>4x-3x=-20-6\\=>x=-26[/tex]

Verification :-

(putting the value of x = -26 )

[tex]\frac{x+5}{x-2} \\\\=>\frac{-26+5}{-26-2} \\\\=> \frac{-21}{-28} \\\\=>\frac{21}{28}[/tex]

Reducing  [tex]\frac{21}{28}[/tex]  by 7 gives  [tex]\frac{3}{4}[/tex] .

Answer:

[tex]y=8[/tex]

[tex]RS=77, ST=31[/tex]

Step-by-step explanation:

Note that the entire segment RT is the combined lengths of RS and ST. So:

[tex]RT=RS+ST[/tex]

We know that RT is 108, RS is (9y+5), and ST is (3y+7). Substitute:

[tex]108=(9y+5)+(3y+7)[/tex]

On the right, combine like terms:

[tex]108=(9y+3y)+(5+7)[/tex]

Add:

[tex]108=12y+12[/tex]

Subtract 12 from both sides. The right cancels:

[tex]96=12y[/tex]

Divide both sides by 12:

[tex]y=8[/tex]

So, the value of y is 8.

To find RS and ST, substitute 8 for y. So:

[tex]RS=9y+5[/tex]

Substitute 8 for y:

[tex]RS=9(8)+5[/tex]

Multiply:

[tex]RS=72+5[/tex]

Add:

[tex]RS=77[/tex]

Do the same for ST:

[tex]ST=3y+7[/tex]

Substitute 8 for y:

[tex]ST=3(8)+7[/tex]

Multiply:

[tex]ST=24+7[/tex]

Add:

[tex]ST=31[/tex]

Answer: Subtract

Step-by-step explanation: Make your denominator equal using the concept of LCM, then subtract the numerators accordingly. Rewrite each fraction to its equivilent fraction with a denominator equal to the LCM=30, then you need to subtract the numberators, but make sure to reduce your answer to the lowest possible term. I hope this helps.

Answer:

1) From Columbus to San Juan, Sam flies 2,028 miles

2)Sam will have 460 miles more miles to fly to Kralendijk  

Step-by-step explanation:

The given information are;

The total (flight) distance from Columbus, Ohio to Kralendijk, Bonaire = 2,488 miles

The distance Sam flies from Columbus to Miami, Florida = 995 miles

The distance Sam flies from Miami to San Juan = 1,033 miles

1) Therefore, the number of miles Sam travels flying from Columbus to San Juan is given as follows;

The number of miles Sam will have to travel flying from Columbus to San Juan = (The distance Sam flies from Columbus to Miami, Florida) + (The distance Sam flies from Miami to San Juan)

The number of miles Sam will have to travel flying from Columbus to San Juan = 995 miles +  1,033 miles = 2028 miles

The number of miles Sam will have to travel flying from Columbus to San Juan = 2,028 miles

Therefore, from Columbus to San Juan, Sam flies 2,028 miles

2) The number of more miles Sam has to fly to Kralendijk from Sam Juan is therefore;

The number of more miles Sam has to fly to Kralendijk from Sam Juan = (The total (flight) distance from Columbus, Ohio to Kralendijk, Bonaire) - (The number of miles Sam will have to travel flying from Columbus to San Juan)

The number of more miles Sam has to fly to Kralendijk from Sam Juan = 2,488 miles  - 2,028 miles = 460 miles.

The number of more miles Sam has to fly to Kralendijk from Sam Juan = 460 miles.

Therefore, Sam will have 460 miles more miles to fly to Kralendijk  

From the division of the trip into parts, it is found that:

--------------------

--------------------

Since Columbus to Miami is 995 miles and Miami to San Juan is 1033 miles, we have that the distance from Columbus to San Juan, in miles, is of:

[tex]995 + 1033 = 2028[/tex]

Thus:

From Columbus to San Juan, Sam flies 2028 miles.

--------------------

[tex]2028 + x = 2488[/tex]

[tex]x = 2488 - 2028[/tex]

[tex]x = 460[/tex]

Thus:

He will have more 460 miles to fly.

The mean increased, but the median stayed the same

Step-by-step explanation:

hope it help luvs

The mean increased, but the median remained constant If new dogs' weights are added to the data set.

The mean of a data set is defined as the ratio of the sum of observations to the total number of observations. It can be referred to as the average of a specific set of data or the arithmetic mean.

The formula for the mean of a given set of data is as follows:

Mean = Sum of Observations/Total number of observations

Given the set of observations as :

16, 34, 44, 20, 50, 19, 30, 54

Arrange the data in ascending order, we get

16, 19, 20, 30, 34, 44, 50, 54

The median of the given data would be (30+34)/2 = 32.

Here, n = 8

⇒ ∑x = Sum of Observations

⇒ ∑x = 267

Mean = ∑x/n

Mean = 267/8

Mean = 33.375

If two more dogs weighing 25 pounds and 45 pounds come to the kennel.

Arrange the given data in ascending order, we get

16, 19, 20, 25, 30, 34, 44, 45, 50, 54

The new median of the data would be (30+34)/2 = 32.

New mean = 337/10 = 33.7

Therefore, the mean increased, but the median remained constant If new dogs' weights are added to the data set.

A withdrawal is taking money out which is a negative value.

She took $18 out so it would be written as -18.

The answer is:

A number line going from negative 20 to positive 20. A point is at negative 18.

Answer:

Carly withdraws $18 from her bank account.

We assume that Carly has $x in her account. She withdraws $18 from her bank account.

So we have to subtract $18 from $x amount.

Which is $x - 18.

So we are subtracting $18 from her account.

It should be represented by an integer -18.

Now we have to identify the which number line represents -18.
