What is the length of BC¯¯¯¯¯ ?
balandron [24]

Answer:

The length of BC is 17

Step-by-step explanation:

\angle b = \angle c

Then sides  AC  and AB  are also equal

On equation their values

2X - 8 =  X+9

2X = X + 9 +8

2X = X + 17

2X - X = 17

X =  17

The length of BC = X =  17

$12.25 pen set; 60% discount
Inessa05 [86]
As you want a 60% discount, you must find 40% of $12.25.

40% of $12.25 is the same as 2/5 of $12.25.

Now, 12.25 / 5 = 2.45

And, 2.45 x 2 = 4.90

--------------

This means that 60% off $12.25 is $4.90.
