The Hansen family bought 2 child and 2 adult movie tickets and paid $36.50. The Owens family bought 5 child and 2 adult tickets and paid $60.50. How much does a child movie ticket cost?

Set up a two-variable equation x is child tickets and y is adult.- 2x+2y=36.5 and 5x+2y=60.5 Then do equation 1 minus equation 2. You get -3x=-24 x = 8

Then plug it in to the equation 5(8)+2y=60.5 40+2y=60.5 2y=20.5 y=10.25

For the answer, it is 8.

Hope this helps :D

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°

-81 -56 -27 0 81
