1.9 < -5p       divide both sides by -5 and reverse the inequality sign

-1.9 / 5  > p

Absolute value measures the distance a number is from "0"  on the number line

So......4  is 4 units from "0".......so......

l 4 l    =   4

12-15r+10=17   combine like terms on the left

22 - 15r  = 17     subtract 22 from both sides

-15r = - 5      divide both sides by -15

r =  -5 / -15     =  1 / 3

Note   576 = 24^2  =  24 * 24   = ( 6 * 4) * (6 * 4)  =  (3 * 2 * 2 * 2) * (3 * 2 * 2 * 2)  =  (3 * 2*3) * (3 * 2^3)  = 3^2 * 2^6

If you mean "divisors".....we have  1 | 2 | 3 | 4 | 6 | 8 | 9 | 12 | 16 | 18 | 24 | 32 | 36 | 48 | 64 | 72 | 96 | 144 | 192 | 288 | 576

3* sqrt(2) * sqrt(6) =

3  *sqrt (12)  =

3* sqrt (4 * 3)  =

3* sqrt (4) * sqrt (3) =

3 * 2 * sqrt (3)  =

6 *  sqrt (3)

4i     well i could just be a normale pronumeral like   x or y or a

but more likely

i = square root of -1

\(4i=4\sqrt{-1}\)

This is an imaginary number becasue everyschoolchild knows you cannot square a real number and get a negative answer.  That is impossible!!!     :)

EP is correct.....the difference here is in the words  "of" and "more"

Consider......if the question had said the price was 100% of what it was....it would be exactly the same price  = $100

But...if the question had said the price is 100% more than what it was.......the price would have doubled = $ 200

Since the question uses "of"....consider

100% of  $100 =  $100

200% of  $100 =  $ 200

300% of $100  =  $ 300

So......350%  of $100  =  $350

No!!. Anytime you see a % sign, you have to treat it consistently. If it said " the price is 3.5 times what it was", then you would be right. Proof: 350/100 - 1 =250% NOT 350% they state.

thanks for the help XD

Time to get offline and go outside for some fresh air?

The question does not state it has gone up 350%  ...the wording says it is 350% of what it was...

That is why I answered the question the way I did.

"...A report says that a theater ticket is now 50% of what it was 20 years ago....'      the answer would be $50.

If it said it was 50% MORE than it was 20 years ago it would be $ 150

Tangent of angle relative to horizontal is given by

TAN =  opposite / adjacent  = 1490 /(- 300) =  -78.616  degrees from 180 degrees  or  101.4 degrees from the 'zero' angle portion of the horizontal....(when rounded to the nearest 0.1 degree)

1.12   = 

1 + 12/100  =

1 + 3/25  =

25/25 + 3/25 =

28 / 25

NO!!!.  Suppose the price had gone up by 50%, what would a $100 ticket cost today?

(50/100 +1) x $100 =$150. EXACTLY  the same principal applies for 350%!!!!!.

$100 x (3.5) = $ 350.00

If it is 350% MORE than it was 20 years ago (the question does not ask this)  then  it is  100 + 100 (3.5) = 450.00

-m - 7m  =

-1m - 7m =

-8m

 2x - y = 6     add y to both sides....subtract 6 from both sides

2x - 6  = y

SO    a^2 + b^2  +  c^2  = 200   (given in the question)

we know from Pythag theorem that   ( a^2 + b^2 )  = c^2    Substitute this into the first equation results in:

c^2 + c^2  = 200

c^2 = 100

c = hypotenuse = 10  

350% =350/100 =3.5

(3.5 +1) x $100 =$450 of today's money.

7, 6, 14, 5, 2, 3, 11, 3, 4 

7 * 6 + 14 + 5 + 2 + 3 + 11 + 3 + 4  =

42 + [14 + 5 ] + [2 + 3] + [11 + 3 + 4]  =

42 + 19 + 5 + 18 =

42 + 24 + 18 =

66 + 18  =

.A mixture of 30 liters of paint is 25% red tint, 30% yellow tint and 45% water. 5 liters of yellow tint are added to the original mixture. The percent of yellow tint in the new mixture is.

25% x 30 =7.5 liters of red tint.

30% x 30 =9.0 liters of yellow tint.

45% x 30 =13.50 liters of water.

9 + 5 =14 liters of yellow tint

30 + 5 =35 liters of new paint

14/35 =40% is yellow tint

7.5/35=21 3/7 is red tint

13.50/35 =38 4/7 is water.

 A mixture of 30 liters of paint is 25% red tint, 30% yellow tint and 45% water. 5 liters of yellow tint are added to the original mixture. The percent of yellow tint in the new mixture is

The original amount of yellow tint  = 30 * 30%  = 9 liters

If 5 liters of yellow tint are added, we now have 14 liters of yellow tint

So.......the percent of yellow tint in the new mixture  =  14 / [30 + 5]  =  14/35 = 40%

40%
