Ana is using a photocopier to make 315 copies of a poster. It takes 3
minutes to print 63 posters. If the
photocopier continues to print at the
same rate, how many minutes will it
take to complete the job?

divide 63 by 3 to get how many copies will be made in 1 min, 63/3= 21

divide 315 to 21 to know how many min it will take= 315/21= 15

It will take 15 min to make 315 copies!

Step-by-step explanation:

Hope this helps!!!

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°
