You can find the unit rate when given a rate by setting up a proportion of the rate equal to how many per one.
40 miles per 2 hours = 20 miles per one hour.
20 miles/hour is a unit rate. (How many per one?)

Answer: 4d + 3
Step-by-step explanation:
Megan's daughter's age = d
Based on the information given, since Megan's age is three years more than four times her daughter's age, this can be written mathematically as:
= (4 × d) + 3
= 4d + 3
Therefore, Megan's age is 4d + 3.
For example, if the daughters age is 7 years, Megan's age will be:
= 4d + 3
= 4(7) + 3
= 28 + 3
= 31 years
87-10= 77 F
