We use unit rates in everyday day life, and it’s become quite useful. For example... : we use them to know how far a car or person can go ( with ) - a certain amount of time.
Unit Rates : When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour.
The answer would be 4.5. or y=4.5x
This is because if you divide 13.5 by 3 it equals 4.5
X² + 6x = 22
x² + 6x = 31 - 9
x² + 6x + 9 = 31
(x+3)² = 31
Answer:
67°
Step-by-step explanation:
● cos<PQR = adjacent/hypotenus
● cos<PQR = 5/13
● cos< PQR = 0.384
Using a calculator:
● cos^-1(0.384) = 67°
● <PQR = 67°
