Answer: 3 - x

Step-by-step explanation: With

Subtraction be careful. 3 - x is not the same as x - 3. You have to keep the values given in order.

dude google works search it up sorry bro  just needs some points you get it raight

Step-by-step explanation:

Answer:

Step-by-step explanation:

In this problem we must first of all write the inequality that describes the problem.

Given that

1. you have a limit of $400

2. there is an initial fee of $50

3. monthly payment is $45

let the number of months be n

therefore

[tex]50+45n\leq 400\\\\45n\leq 400-50\\\\45n\leq350[/tex]

Divide both sides by 45 we have

[tex]n\leq \frac{350}{45} \\\\n=\frac{70}{9} \\\\n= 7.77\\\\[/tex]

approximately you are going to be member for 8 months

Complete question:

In 2016, the city of Rio de Janeiro had a population density of 5377 people/km2.

What was the population density of Rio in people per square meter?

Answer:

0.005377 peope/m²

Step-by-step explanation:

Given that :

Population density of Rio in 2016 = 5377 people/km²

To obtain population density in people per square meter, we convert 5377people/km² to people per m²

Recall:

1000 m = 1km

Hence,

5377 people/km² = 5377 people / (1000²)m

= (5377/1000000)people/m²

= 0.005377 peope/m²

Answer:

0.005377

Answer:

220

Step-by-step explanation

Answer:

see below

Step-by-step explanation:

The area is given by

A = l*w

A = (4x-1) ( 3x+6)

FOIL

first 4x*3x =12x^2

outer 6*4x = 24x

inner -1*3x = -3x

last  -1 *6 = -6

Add together

12x^2 +24x-3x-6

12x^2 +21x-6

Answer:

The area is given by

A = l*w

A = (4x-1) ( 3x+6)

first 4x*3x =12x^2

outer 6*4x = 24x

inner -1*3x = -3x

last  -1 *6 = -6

Add together

12x^2 +24x-3x-6

12x^2 +21x-6

Answer:

x = 32 y = 16 z = 64

Step-by-step explanation:

x is the 1st number

y is the 2nd number

z is the 3rd number

The first number is twice the second number so

x = 2 y

The third number is twice the first number.

z = 2 x

Their sum is 112

x + y + z = 112

Plus in what we know:

x + y + z = 112

2 y + y + 2x = 112

3y + 2x = 112 Let's solve for y and subtract 2x from each side

3y = 112 - 2x  Divide both sides by 3

y = [tex]\frac{112 - 2x}{3}[/tex]

Now plug our answer back in to solve for x.

x = 2y

x = 2 ( [tex]\frac{112 - 2x}{3}[/tex] )

x = (224 - 4x) / 3    Multiply each side by 3.

3x = 224 - 4x         Add 4x to each side

3x + 4x = 224

7x = 224              Divide each side by 7

7x / 7 = 224 / 7

x = 32

Now we can solve for z.

z = 2x

z = 2 ( 32 )

z = 64

Now we can solve for the numerical value of y.

x + y + z = 112

32 + y + 64 = 112

96 + y = 112       Subtract 96 from each side.

y = 112 - 96

y = 16

Answer:

1st number = 36

Second = 16

Third = 64

Step-by-step explanation:

We have 3 numbers

Let's call the second number g

Then the first would be , 2x g = 2g

Then the third would be twice the first = 2 x 2g = 4g

We add up all numbers and equate it to 112

2g + g +4g = 112

7g = 112

g = 112/7

g = 16

First number = 2g = 2x16 = 32

Second number = g = 16

Third number = 4g = 4x16 = 64

Therefore the numbers are 32, 16, 64.

I hope this helps!

Answer:

n = ±6

Step-by-step explanation:

n² + 4 = 40

n can be solved by finding the square root

n²  = 40 - 4

n²  = 36

n = √36

n = ±6

Answer:

He bought 1 small bag and 6 large bags.

Step-by-step explanation:

We can set up 2 equations with the given information.

5x+8y=45

x+y=6

We can rearrange the second equation to solve for x.

x=6-y

Now we substitute x for 6-y in the first equation

5(6-y)+8y=45

30-5y+8y=45

30+3y=45

y+10=15

y=5

x=1

He bought 1 small bag and 6 large bags.

Answer:

1/6

Step-by-step explanation:

There are six sides on a die and only one of them has a 4

P( 4) = number of sides with a 4/ total number of sides

        = 1/6

Answer:

P (4) = 1/6

Step-by-step explanation:

The probability can be found by creating a fraction. The numerator is the number of favorable outcomes and the denominator is the total number of outcomes.

P (4) = sides with a 4 / total sides

The standard dice has 6 sides numbered 1 through 6.

P (4) = sides with a 4/ 6

Only one side on the cube has a 4.

P (4) = 1/6

This fraction cannot be simplified further, so it is our final answer.

The probability of rolling a 4 on a standard dice is 1/6

Answer:

$18

Step-by-step explanation:

Given:

y = 0.9x - 4.5

Where,

x = age in years

y = hourly pay in dollars

what is the best prediction for the hourly pay of a 25 year old?

That is, find y when x=25

y = 0.9x - 4.5

= 0.9(25) - 4.5

= 22.5 - 4.5

= 18

y = $18

The prediction for the hourly pay of a 25 year old is $18

Answer:

$18:00

Answer:

Step-by-step explanation:

1. Finding  [tex]\overrightarrow{AB}[/tex]  (or [tex]\overrightarrow{BA}[/tex]):

[tex]\overrightarrow{AB}=\overrightarrow{OA}-\overrightarrow{OB}= \left[\big5\atop\big3\right]-\left[\big2\atop-\big5\right]= \left[\big5-\big2\atop\big3-(-\big5)\right]=\left[\big3\atop\big8\right][/tex]

2. Calculating length of  [tex]\overrightarrow{OA}\,,\ \overrightarrow{OB}\ \text{and}\ \overrightarrow{AB}[/tex]:

[tex]|\overrightarrow{OA}|=\sqrt{5^2+3^2}=\sqrt{25+9}=\sqrt{34}\approx5.831\\\\ |\overrightarrow{OB}|=\sqrt{2^2+(-5)^2}=\sqrt{4+25}=\sqrt{29}\approx5.385\\\\ |\overrightarrow{AB}|=\sqrt{3^2+8^2}=\sqrt{9+64}=\sqrt{73}\approx8.544[/tex]

3. Calculating perimeter:

[tex]P=|\overrightarrow{OA}|+|\overrightarrow{OB}|+|\overrightarrow{AB}|=\sqrt{34}+\sqrt{29}+\sqrt{73}\approx5.831+5.385+8.544=19.76[/tex]

Answer:

40 and 89

Step-by-step explanation:

let x be the number then the other number is 2x + 9, then

x + 2x + 9 = 129, that is

3x + 9 = 129 ( subtract 9 from both sides )

3x = 120 ( divide both sides by 3 )

x = 40

Thus the numbers are

x = 40 and 2x + 9 = 2(40) + 9 = 80 + 9 = 89

Answer:

x = 2

AB = 15

BC = 15

AC = 30

Step-by-step explanation:

Given that B is the midpoint of AC, then AB = ½ of AC.

AB is given as 3(3x - 1),

AC = 5(2x + 2),

Therefore:

[tex] 3(3x - 1) = \frac{1}{2}*5(2x + 2) [/tex]

Solve for x

[tex] 9x - 3 = \frac{5}{2}(2x + 2) [/tex]

Multiply both sides by 2

[tex] 2(9x - 3) = \frac{5}{2}(2x + 2)*2 [/tex]

[tex] 18x - 6 = 5(2x + 2) [/tex]

[tex] 18x - 6 = 10x + 10 [/tex]

[tex] 18x - 10x = 6 + 10 [/tex]

[tex] 8x = 16 [/tex]

Divide both sides by 8

[tex] x = 2 [/tex]

[tex] AB = BC = 3(3x - 1) [/tex]

Plug in the value of x

[tex] AB = BC = 3(3(2) - 1) [/tex]

[tex] = 3(6 - 1) = 3(5) = 15 [/tex]

[tex] AC = 5(2x + 2) [/tex]

[tex] AC = 5(2(2) + 2) [/tex]

[tex] AC = 5(4 + 2) = 5(6) = 30 [/tex]

Answer:

The two data sets have different distributions and different ranges.

Step-by-step explanation:

When you subtract for both of the ranges they are different numbers. So that's the second part. The numbers along the bottom are different too so that is the different distributions.

Answer:

The two data sets have different distributions and different ranges.

Step-by-step explanation:

The shape of the data for German male adult heights is skewed left, but the shape of the data for female adult heights is close to symmetric. So, the two data sets have different distributions.

Each data set has the same minimum height of 145 centimeters. However, the maximum male adult height is 220 centimeters, and the maximum female height is 185 centimeters. So, the two data sets have different ranges.
