Answer:

x = 4/5

Step-by-step explanation:

3(x-4)=12x

3x-12=12x

3x+12x-12=12x-12x

15x-12=0

15x-12+12=0+12

15x=12

15x/15=12/15

x = 4/5

What is the common difference for this arithmetic sequence?<br> 31, 48, 65, 82, ...
sergejj [24]

Answer:

d = 17

Step-by-step explanation:

The given arithmetic sequence is :

31, 48, 65, 82, ...

We need to find the common difference for this sequence.

First term, a₁ = 31

Second term, a₂ = 48

Common difference = a₂-a₁

= 48-31

= 17

So, the common difference for this arithmetic sequence is equal to 17.

Moosa's sister is six years younger than 3 times his age. The sum of their ages is 30. How old is Moosa?
elena55 [62]

Suppose Moosa is ( x ) years old ,

Thus Moosa's sister is ( 3x - 6 ) years old .

The sum of their ages is 30 :

( x ) + ( 3x - 6 ) = 30 ==》 4x - 6 = 30

==》 4x = 36

==》 x = 9

So Moosa is 9 years old .
