Mia is three years older than twice her sister brooke's age. The sum of their ages is less than 30. what is the greatest age Bro
Pachacha [2.7K]

Answer: 9

Step-by-step explanation: You can start by setting this up as an equation, where X is Brooke’s age.

X + 2(x)+ 3 = 30

The 2(X) + 3 signifies the part of the problems identifying that Mia is twice her sisters age plus 3 years.

Combine x’s

3x + 3 = 30

Subtract 3 from both sides to isolate the x term

3x= 27

Divide both sides by 3 to reduce to a single x

X= 9 , which is brooke’s age

Pre calculus law of sines
lakkis [162]

Answer:

AB = 6.5

Step-by-step explanation:

C = 59°

AC = 7

CD = 6

AB = ?

Apply the Law of Cosines, which is AB² = AC² + CD² - 2(AC)(CD)*Cos(C)

AB² = 7² + 6² - 2(7)(6)*Cos(59)

AB² = 85 - 43.26

AB² = 41.74

AB = √41.74

AB = 6.5 (nearest tenth)
