Write each ratio as a rate.
a. the ratio of miles to the number of hours is 434 to 7.
b. the ratio of the number of laps to the number of minutes is 5 to 4.

a. 62 miles/hour

b. 1.25 laps/minute

Step-by-step explanation:

a. ratio of miles to the number of hours is 434 to 7 can also be written as

= 62 miles/hour

therefore rate or speed= 62 miles/hour

b.

= 1.25 laps/minute which rate or speed

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°
