What is equivalent to 9 out of 25

Mathematics

Answer:

9/25 = 36/100 = 36% . . . . "out of" meaning "parts of"

25 - 9 = 16 . . . . "out of" meaning "from"

Step-by-step explanation:

The wording "out of" can be taken a couple of ways in this usage. Context is important, and no context is provided here.

Often, it means "parts of" as in 9 of 25 parts, or 9/25.

An equivalent fraction is 18/50 or 36/100 = 0.36 = 36%.

This would be the usual meaning in the context of probability.

This wording can also mean 9 parts taken from 25, so the remaining amount is 16. Equivalents might be 10 from 26, or 4 from 20.

Solve by factoring 2x^2=19x+33

oksian1 [2.3K]

2x^2 - 19x - 33 = 0 

The factors of 2 are 1 x 2. 
The factors of 33 are 1 x 33 and 3 x 11. 

Using Guess and Test and FOIL, find a combination that gives you a middle term of -19x: 

(2x + 3)(x - 11) = 0. 

Using the principal of zero product, solve each equation for x: 

2x + 3 =0 and x - 11 =0. 

The two solutions are x = -3/2 and x = 11.

borishaifa [10]

Answer:

x=10

Step-by-step explanation:

Lets use a ratio.

3:2 (12 to 8)

We need to scale the x+4 up 3/2 to be equal to 2x+1

(3/2) x+4 = 2x+1

1.5x+6=2x+1

-1.5x -1.5x

6=0.5x+1

-1 -1

0.5x=5

x=10
