The common ratio of a geometric sequence is the ratio of any term to the one before it. Here, you can find it by
... 6/-2 = -3
or, if you prefer the minus sign in the numerator, ...
... -18/6 = -3
or the ratio of any other sequential terms.
The common ratio is -3.
Numbers less than 1 have a negative exponent
Here there are 2 digits after decimal point so the answer is
5 * 10^-2
Well you have to leave x by it self so you would subtract z first and move it to the right now you would be left with m=bx now divide by b to leave the x by itself and get m/b=x
Hope this helps
0 ≤ q ≤ 5/3 (this is the answer if you’re looking for the inequality of q)
112
suplementry angle add to 180 so 180_68=112
