Lin spent 80 minutes doing homework on Monday. Each day from Tuesday through Friday, Lin spent half as much time doing homework as the day before.
How much total time did Lin spend doing homework, from Monday through
Friday? Explain how you know. *

240 minutes

Step-by-step explanation:

Half of 80 is 40. So multiply 40 by 4 which is 160 minutes then add the 80 which equals 240 minutes

sine

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°
