Solve and show work: 1. solve x-8a/6=3a-2x for x 2. solve 3x-2a=7a for a 3. solve 3(bx-2ab)=b(x-7a)+3ab for x 4. solve 2x+3b/9=x-b/2

For solving an equation for a variable, we need to isolate the variable in the left side of the equation,

1. Given equation,

( By cross multiplication ),

2.

3.

4.

( For x )

 ( For b )

the perimeter is increased by a factor of 2

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
