Ron is tiling a countertop. he needs to place 54 square tiles on each of 8 rows to cover the counter. he wants to randomly place 8 groups of 4 blue tiles each and have the rest of the tiles be white. how many white tiles wwill ron need ?

22 white and 32 blue since 8 times 4 is 32 and 54 minus 32 is 22.

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°
