-3 1/9 - (-2 1/3)
p. s help me please , if you do it your're special ;P

-7/9

Step-by-step explanation:

-3  1/9 -  -2 1/3

Subtracting a negative is adding

-3  1/9 +2 1/3

We need to get a common denominator of 9        1/3 *3/3 = 3/9

-3 1/9 + 2 3/9

These have opposite signs, so we subtract the smaller from the larger and take the sign of the larger

3 1/9 - 2 3/9

We have to borrow from the 3 because the fraction is not large enough 3/9 is larger than 1/9

The 3 becomes a 2 and 1/9 becomes 1/9 + 9/9 = 10/9

2  10/9 - 2 3/9  = 7/9

We take the sign on 3 /19 which was negative

-7/9

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
