Four times a number, subtracted from four, is twice the number. Find the number.

Answers

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

let the number be n , then

4 - 4n = 2n ( add 4n to both sides )

4 = 6n ( divide both sides by 6 )

[tex]\frac{4}{6}[/tex] = n

The number is [tex]\frac{2}{3}[/tex]

Answer:

Let the number = x

4 - 4x= 2x

4 = 2x+4x

4 = 6x

x = 4/6

x = 2/3

S is the midpoint of RT, and RS=14. find RT

Answers

rt =12.9 i his jdjdfjd and djrjd

The segment midpoint divides a segment into 2 halves by definition.

By the Segment Addition Postulate, you can add two adjacent segments to get the total length of the segment.

Given that RS=14

That means that 14 is 1/2 if the total segment length, so we know that segment RT is also = to 14 to make the other half.

We have two lengths that are 14, so we simply add them together to find the total segment’s length.

14+14=28.

The total line segment is 28.

The fish population in local lake is 10,000 the population increases by half every year which function represents the fish population after X years
F(x)= 10,000 parentheses (1.5)^x
Pls help it would mean a lot I’m stressing need ASAP

Answers

Answer:

5. [tex]f(x) = 10,000 (1.5)^x[/tex]

Step-by-step explanation:

==>>We would have to multiply the original amount by 1.50^x because the initial amount would be 1, and 50% increase would be .5 so 1.5 and you raise it to the number of years to show the total increase.

Let's test it

Initial: 10,000

After 1 year

10,000 + (.5*10000)

10,000 + 5000 = 15,000

After 2 years

15,000 + (.5*15000)

15,000 + 7500 = 22,500

Let's try our equation.

[tex]f(x) = 10,000 (1.5)^x[/tex]

[tex]x=2[/tex]

[tex]10,000(1.5)^2[/tex]

[tex]10,000(2.25) = 22,500[/tex]

Answer:

Step-by-step explanation:

Divide the Y values by the X values to check your answer

Answer:

Step-by-step explanation:

The question asks for a 0.3 constant of proportionality between 'x' and 'y'.

So, if you multiplied 0.3 to the number in 'x', you would get the number in 'y'.

By process of elimination, we can find that in A, 0.3 * 6 is not 2 and it's the same for all the other numbers in the table.

For B, 3*0.3 is not 1.8 and 0.3 multiplied by the other numbers in B do not match the number in y.

The only answer that matches is C, 4*0.3 is 1.2, 8*0.3 is 2.4, and 13*0.3 is 3.9.

So, the answer is C.

Answer:

425ft.

Step-by-step explanation:

Just add 395 and 30 together.

Hope this helps. Pls give brainliest!

Answer:

425 ft

Step-by-step explanation:

So the snorkeling was 30 ft BELOW sea level while the hike was 395 ft ABOVE sea level.

Below is negative so 30 ft below is -30

Above is positive so 395 ft above is 395

the difference between 395 and -30 looks like this:

395- (-30)

So you can simplify to get this equation:

395+30

which is 425

So the difference between the snorkel and hike is 425 ft

Hope this helps!

Answers

Answer:

1) A number that divides another number evenly is called a factor of that number. For example, 16 can be divided evenly by 1, 2, 4, 8, and 16. So the numbers 1, 2, 4, 8, and 16 are called factors of 16.

2) A number that divides a given set of numbers is called a common factor of the numbers.

4x - 5 = 2(2x + 1)

Step-by-step explanation:

4x - 5 = 2(2x + 1)

4x - 5 = 4x + 2

Then you would subtract the 4x on each side leaving you with:

-5 = 2

And obviously the value of -5 does not equal the value of 2 so therefore this equation has no solution

I’m confused with this question, so I can’t find the median because there is repeating numbers so yeah

Answers

Answer:

To find the mean, add all numbers together and divide by the amount of numbers.

Total of number = 660

Number of numbers = 11

660/11 = 60

Answer:

The median is 70.

Step-by-step explanation:

I believe you may have mixed up median with mode.

Here are the definitions of both:

Mode - The value that appears the most in a data set

Median - The middle number in a list of numbers ordered from least to greatest

To find the median of this data set, we must arrange the numbers from least to greatest!

20, 20, 30, 50, 60, 70, 70, 80, 80, 90, 90

Now we just have to figure out the middle number...which is 70!

Write the equation of a line with a point at `(-3,2)` and has a slope of `\frac{1}{2}`.

Answers

Answer:

y = (1/2)x + 7/2

Step-by-step explanation:

y = ax + b (general form of a linear function)

a = 1/2 (slope)

y = (1/2)x + b

(-3, 2) is on the line, 2 = (1/2)*(-3) + b

2 = -3/2 + b

b = 2 + 3/2

b = 7/2

equation: y = (1/2)x + 7/2
