0.5(4−2a)=a−1.8 solve for a pl

Step 1. Expand

2 - a = a - 1.8

Step 2. Add a to both sides

2 = a - 1.8 + a

Step 3. Simplify a - 1.8 + a to 2a - 1.8

2 = 2a - 1.8

Step 4. Add 1.8 to both sides

2 + 1.8 = 2a

Step 5. Simplify 5 + 1.8 to 3.8

3.8 = 2a

Step 6. Divide both sides by 2

3.8/2 = a

Step 7. Simplify 3.8/2 to 1.9

1.9 = a

Step 8. Switch sides

a = 1.9

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 ! ~
