Let x be for unknown number. Let x be first number . X+1 To be second number .x+2be third number. X+(x+1)+(x+2)=312. Simplify to get 3x+3=312 . Subtract 3 from both sides 3x-3=312-3. Once you subtract get 3x=109.then divide 3 both sides . 3x/3=309/3. To get x= 103. Now once you have that First number 103. Second number 103+1=104 . And third number 103+2=105. To check add them 103+104+105=312

deff fn [24]

Step-by-step explanation:

$\\ \tt{:}\leadsto \frac{2 - 3x}{4 - 8} = \frac{3x}{4} \\ \\ \tt{:}\leadsto 4(2 - 3x) = 3x(4 - 8) \\ \\ \tt{:}\leadsto 8 - 12x = 3x( - 4) \\ \\ \tt{:}\leadsto 8 - 2x = - 12x \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \tt{:}\leadsto 8 = - 12x + 2x \\ \\ \tt{:}\leadsto 8 = - 10x \\ \\ \tt{:}\leadsto x = \frac{ - 10}{8} \\ \\ \tt{:}\leadsto x = \frac{ - 5}{4}$

Find the value of x<br>9.10.12,x, 20.25 ; The median is 14.

Elodia [21]

Answer: 16

Step-by-step explanation:

9,10,12,x ,20, 25 so we know the median is 14 which is the middle number.

Since the numbers are 6 it means there will be 2 middle numbers and if you divide them it will be 14.

we know one of the middle numbers is 12 and we trying to find x .

So we could use the equation x + 12 = 2(14)

x + 12 = 28

-12 -12

x= 16 so X is 16. check: 16+12=28/2 is 14.
