Minchanka [31]3 years ago

First you need to get x on one side so subtract 3x from both sides which will leave you with 8=2x-20. Next add 20 to both sides to get 28=2x. Then divide everything by 2 and you should get x = 14.

OverLord2011 [107]

Answer:

Alana is 13 years old.

Step-by-step explanation:

Assuming you meant Mazo = Maisel,

You start from the bottom:

Amelia is 10 years younger than 17-year-old Maisel.

Amelia is 7 years old. (17-10)

Ernie is 2 years older than 7-year-old Amelia.

Ernie is 9. (2+7)

Alana is 4 years older than 9-year-old Ernie.

Alana is 13 years old. (4+9)

Hope this helps!

Consider isosceles ΔXYZ.
Rom4ik [11]

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The length of the legs XY and YZ is equal to 39 units.

<h3>What is a triangle?</h3>

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°. An isosceles triangle has two sides out of three equal.

A.) The value of n can be found by equating XY and XZ together,

XY = XZ

9n + 12 = 15n - 6

12 + 6 = 15n - 9n

18 = 6n

n = 3

Hence, the value of n is 3.

The length of different legs of the triangle is,

B.) XY = 9n + 12 = 9(3) + 12 = 27 + 12 = 39

C.) YZ = 15n - 6 = 15(3) - 6 = 45 - 6 = 39

Hence, the length of the legs XY and YZ is equal to 39 units.
