You can probably find the properties here

Suppose a classmate is having difficulty solving 4(x - 7) > 6x + 2 + 8x . Explain how to slove the inequality, showing all the necessary steps and identifying the properties you would use.

Mmm you can work out what the names of the properties are.

4(x - 7) > 6x + 2 + 8x

4x - 28 > 6x + 2 + 8x

4x - 28 > 14x + 2 

4x - 28-14x > 14x + 2 -14x

-10x - 28 >  2 

-10x - 28+28 >  2 +28

-10x  >  30

-x > 3

x< -3

Let the present age of the daughter =D

Her father's age =50 - D

2(D + 8) = (50 - D + 8), solve for D

D = 14 The daughter present age.

50 - 14 = 36 The father's age now, so that:

36 + 8 = 14 + 8

44  and  22 - In 8 years the father will be twice as old as his daughter.

Hi Gamemasterx40,  

Suppose you start with at least $52 in your savings account and deposit $27 each week. Write an inequality to describe how much money m you have after w weeks. If you do this for 11 weeks, will you have enough to buy a bicycle that costs $340? Show your work.

52,   52+27,    52+27*2, ..............    52+27w

After w weeks I will have     52+27w  dollars  

After 11 weeks this equals

52+27*11 = 349

which is enough to buy the bike that I want.    

Mmm  in 3 months I can have that bike

You can use greater than or equal as an inequality since there can be tax or bonus (Depends very much, could be an equality aswell)
m (total) >/= 52 (start value) + 27 . w (weekly deposit)
So, taking 11 as time, you can use
M >/= 52 + 27*11
M >/= 52 + 297
M >/= 349 

If the bike costs you 340, and obviously 349 > 340
Yes, you can buy one

If you start by asking what the square root of something is you can work your way back to find the answer.

56286372367*1000 = 56286372367000

56286372367*1000 = 56286372367000

what times 6=640

N x 6 = 640 divide both sides by 6

N = 640 / 6

N =106 2/3

-162 I think. 

It should be about 7.14142842854 Hope this helps! 

Solve for x:
(x-1)^2 = 2

Take the square root of both sides:
x-1 = sqrt(2) or x-1 = -sqrt(2)

Add 1 to both sides:
x = 1+sqrt(2) or x-1 = -sqrt(2)

Add 1 to both sides:
Answer: |x = 1+sqrt(2)       or       x = 1-sqrt(2)

The calculator has brackets!!!. Just look above 7 and 9!!.

4(x - 7) > 6x + 2 + 8x

4x -  28 > 14x + 2 subtract 4x from both sides

- 28  > 10x + 2 subtract 2 from both sides

- 30 > 10x divide both sides by 10

- 3 > x Reverse the inequality

x < - 3

Multiply both 50 and 70 by 3. The result would be 2 sides of right triangle. Solve for the 3rd side, the hypotenuse, using Pythagoras's theorem.

m-4.8=7.4

m = 7.4 + 4.8

m = 12.2
