1 2/3*J=15 What is J?
Wewaii [24]

Answer:

Do you mean:

(1+(2/3))j = 15

((3/3)+(2/3))j = 15

((3+2)/3)j = 15

(5/3)j = 15

j = 15 / (5/3)

j = 15 * (3/5)

j = 9

What is ​ BC ​?
gtnhenbr [62]

BC = 18

AB = AC, hence

8x - 4 = 5x + 11 ( subtract 5x from both sides )

3x - 4 = 11 ( add 4 to both sides )

3x = 15 ( divide both sides by 3 )

x = 5

BC = 4x - 2 = (4 × 5 ) - 2 = 20 - 2 = 18
