Alyssa is twice as old as brittany, and jazmyn is 15 years older than alyssa. if jazmyn is 35 years old, how old is brittany? let a represent alyssa’s age in years and bb represent brittany’s age in years.

10 years old

Step-by-step explanation:

Let's put own the data given to us.

Alyssa (a) = 2b

Brittany (b)

Jazmyn (j) = a + 15 = 2b + 15 = 35

Let us solve the equation.

2b + 15 = 35

      2b = 35 - 15

      2b = 20

         b = 20 / 2

         b = 10

Therefore, Brittany is 10 years old.

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
