A man goes into a store and says, “If you give me as much money as I have with me now, I will spend $10 in your store.” The store owner agrees, and the man spends the money.
He goes into a second store and again says, “If you give me as much money as I have with me now, I will spend $10 in your store.” Again, the owner agrees, and the man spends the money.
In a third store, he repeats his proposition. The proprietor agrees, and the man spends the money.
At this point, the man has no money left. How much money did he have to begin with?

Answers

Answer 1

Answer:

$8.75

Step-by-step explanation:

Let x = the amount the man originally had

The man has $x and says "if you give me $x, I will spend $10."

y = amount he has after 1st proposition = x + x - 10 = 2x - 10

He repeats this procedure, now with $2x-10 in his pocket...

z = amount he has after 2nd proposition = (2x - 10) + (2x - 10) - 10 = 4x - 30

He repeats this procedure, now with $4x-30 in his pocket...but this time he is left with zero dollars...

r = amount he has after 3rd proposition = (4x-30) + (4x-30) - 10 = 8x-70 = 0

8x - 70 = 0,

x = $8.75

Angie has already written 19 pages, and she expects to write 1 page for every additional
hour spent writing. How many hours will Angie have to spend writing this week in order to
have written a total of 28 pages?

Answers

Answer:

[tex]9[/tex]

Step-by-step explanation:

[tex]28 - 19 = 9[/tex]

Answer:
9 hours

Explanation:
What we know:
- Angie has already written 19 pages
- Angies writes 1 page per hour

First, we can create the following equation to model this scenario:

Let x be equal to the number of hours that pass.
Total number of pages=1x+19

Now, because Angie wants to write 28 pages in total, we can plug that into the left side of the equation and solve for x, the number of hours.

28=1x+19
Subtract both sides by 19
28-19=1x+19-19
9=1x
x=9

Therefore, Angie would have to spend 9 hours to write a total of 28 pages.

I hope this helps!

Parallelograms don’t understand

Answers

Answer:-43 + 9x = 0

Step-by-step explanation:Simplifying

9x + -43 = 0

Reorder the terms:

-43 + 9x = 0

Solving

-43 + 9x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '43' to each side of the equation.

-43 + 43 + 9x = 0 + 43

Combine like terms: -43 + 43 = 0

0 + 9x = 0 + 43

9x = 0 + 43

Combine like terms: 0 + 43 = 43

9x = 43

Divide each side by '9'.

x = 4.777777778

Simplifying

x = 4.777777778

Which point on the coordinate plane below is (-9, 3)?




Point D


Point C


Point B


Point A

Answers

Answer:B

Step-by-step explanation: x is -9 and y is 3

Since it’s negative you’d go left by 9 blocks and the y is positive so you go up 3

Answer:

The answer is point B

Step-by-step explanation:

I know this because (-9, 3) seems to be located in quadrant 2 because in quadrant 2 along the x-axis it is negative and along the y-axis it is positive. So, when l look in quadrant 2 there seems to be only one point, point B, which if you look at it is 9 units to the left and 3 units upward.
