Solve the system. x 1 minus 2x 2 plus 3x 3 equals negative 5 negative 6x 1 plus 15x 2 minus 25x 3 equals 35 negative 3x 1 plus 12x 2 minus 23x 3 equals 49 Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice.

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.

step-by-step explanation:

not sure but it may be b, as i said i'm not sure.
