You do the brackets first so 3x8 = 24 - 7 = 17
You then do divide so 34/17 = 2
You then do the multiplication so 2x3= 6
Then you have 1-2-6 = - 7
The order you do it in is BIDMAS
B = brackets
I = indices
D = division
M = multiplication
A = addition
S = subtraction
So the answer is - 7
the answer is -8, the 9 is negative and -9+1= -8
1. and 2. is the same question, so the answer to both is <u>direct variation</u>
3. <u>Direct</u> <u>variation</u>
4. <u>Inverse</u> <u>variation</u>
5. I believe it is <u>Inverse</u>, but I'm not 100% certain
Can you give me the problem
AA is why they are similar.
