Answer:

Allana is 2 1/2 and her mother is 15 years old.

Step-by-step explanation:

Let Allana's age be x years then,

her mother's age is 6x.

Using the given information in ten years time we have the equation:-

6x + 10 = 2(x + 10)

6x + 10 = 2x + 20

6x - 2x = 20 - 10

4x = 10

x = 2 1/2

So 6x = 6 * 2 1/2 = 15.

Answer:

x = 4
WX = WY = 25
XY = 17

Step-by-step explanation:

The triangle is isosceles with side WX equal to side WY:

WX = WY

9x -11 = 7x -3

2x = 8 . . . . . add 11-7x

x = 4

Then the side measures are ...

WX = WY = 7(4) -3 = 28 -3 = 25

XY = 4(4) +1 = 16 +1 = 17
