Sinead bought 2 shirts for 15.10 each and a pair of shoes for $42.42 If she paid for the items with a $100 bill, how much change did she receive?

27.38

Step-by-step explanation:

15.10 times 2 is 30.2

30.2+42.42=72.62

100-72.62=27.38

step-by-step explanation:

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°
