If anyone could answer this for me I would very much appreciate it
baherus [9]

Answer:

a3 = 45

Step-by-step explanation:

a1 = 20

an = a(n-1) *3/2  where n is the term number

a2 = a(2-1) *3/2

     a1 *3/2

We know a1 = 20

a2 = 20*3/2 = 30

a3 = a(3-1) *3/2

    = a2 *3/2

We know a2 = 30

    = 30*3/2 = 45

the value of two numbers if their sum is 12 and their difference is 4. write a system of equation and find the two numbers
nikdorinn [45]

x+y=12

x-y=4

Then you solve:

x+y=12

 -y   -y

x=12-y

x-y=4

  +y  +y

x=4+y

4+y=12-y

  +y      +y

4+2y=12

-4        -4

2y=8

divide both sides by 2 to isolate y

y=4

Plug it into one of the equations

x+4=12

 -4    -4

x=8
