Sally’s bank account has $650 in it. Every week sally withdraws $50 to pay for her dog sitter. What is the maximum number of weeks tajar sally can withdraw the money so that there is at least $75 remaining in the account? Write and solve an inequality to find the solution, and graph the solution on a number line.



Pls help 10 pts for this due tmrw!!!

Answers

Answer:11

Step-by-step explanation:I think

answer:  the maximum number of weeks Sally can remove $50 from the account and still have at least $75 is 11 weeks.

show my work :

Let W be the number of weeks Sally has been withdrawing money.  The total in the account would be represented by 650-50W at any given time.

To remain over or equal to $75 the equation to solve is

650 - 50W >= 75

we need to get the variable on one side and the constants on the other so subtract 650 from each side...

-50W >= 75-650

-50W >= -575

Now we need to divide out the coefficient of the variable so divide both sides by -50.   Note that multiplying or dividing an inequality by a negative reverses the inequality so...

W <= (-575)/(-50)

W <= 11.5

So in whole numbers the maximum number of weeks Sally can remove $50 from the account and still have at least $75 is 11 weeks.

What is the fundamental principle of multiplication?
Multiplication is the mathematical operation that is used to determine the product of 2 numbers or more numbers.

We have been given that “A” train leaves a subway station every 12 minutes. An “E” train leaves every 9 minutes.

If both trains just left the station on parallel tracks, then both leave the station together again;

[tex]m = \frac{4}{5}[/tex]

Step-by-step explanation:

Find the slope by using the slope formula:

slope [tex](m) = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Let:

[tex](x_1 , y_1) = (4 , 4)\\(x_2 , y_2) = (9 , 8)[/tex]

Plug in the corresponding numbers to the corresponding variables:

slope [tex](m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{8 - 4}{9 - 4}[/tex]

Simplify. First, subtract, and then simplify, if possible, the slope:

slope [tex](m) = \frac{8 - 4}{9 - 4} = \frac{4}{5}[/tex]

slope [tex](m) = \frac{4}{5}[/tex] is your answer.

how can you find the simplest form of 100/1,000?

Answers

Answer:

0.1

Step-by-step explanation:

To figure this out, since the numbers are pretty much the same with a 1 and 0's, we can take the 100 and subtract the number of zeros in 1,000, which is 3. So, take the decimal point which is by the last 0 on the 100 and move it 3 times because there are 3 zeros in 1,000:

100.0 (This is where the decimal would be in one hundred)

10.0 (This is one decimal point over)

1.0 (This is two decimal points over)

0.1 (This is three decimal points over)

y+2=2/3 (x-4) point slope

Answers

Answer:

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

Step-by-step explanation:

Adding 2 to y is equivalent to [tex]\frac{2}{3}[/tex](x-4). To simplify, we can do

y + 2= ([tex]\frac{2}{3}[/tex])x - ([tex]\frac{2}{3}[/tex])4

(2/3 × x= [tex]\frac{2}{3}[/tex]x) - ([tex]\frac{2}{3}[/tex] × 4= 2 [tex]\frac{2}{3}[/tex])

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

Answer is y=2/3x-2/3
I’m assuming you wish to solve this point slope problem by using algebra.
For this problem you start with 2/3(x-4). You get y+2=2/3x-8/3. Then you move 2 to the other side by subtracting 2. Y=2/3x- 8/3 -2. Y=2/3x-2/3. Is the final answer. Hope this helps.
