Question

multiple choice value of x

Answer 1

Q34.

If BE is the bisector of AD then:

2x - 5 = 5x - 20     |+5

2x = 5x - 15    |-5x

-3x = -15    |:(-3)

x = 5

Q35.

If BE is the bisector of AD, then

5x + 4 = 2x + 7     |-4

5x = 2x + 3     |-2x

3x = 3    |:3

x = 1

Answer 2

Bisect means to cut something into two equal halves. This means that the two lengths are the same.

34.) $2x - 5 = 5x - 20$

First isolate the variable. Add 5 to both sides:

$2x = 5x - 15$

Now subtract 5x from both sides:

$-3x = -15$

x = 5

35.) $5x + 4 = 2x + 7$

--> $5x = 2x + 7 - 4$

---> $5x = 2x + 3$

----> $5x - 2x = 3$

-----> $3x = 3$

So x = 1
