Evaluate [(30 + 6) − 32] ÷ 9 ⋅ 2. (1 point) im doubting myself

8/9

Step-by-step explanation:

Order of operations: Parentheses first.

(30+6)=36,

Then subtract 32

36-32 = 4

Left to right, so don't divide by 18. Instead, divide by 9.

4/9 = 4/9

4/9 times 2/1 = 8/9

6

Step-by-step explanation:

i took the test

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
