Answer:

BK=39/7

Step-by-step explanation:

because NQZ~CBK

so BK/QZ = TZ/KF

(4x+1)/(2x+7) = 27/45 = 3/5

5(4x+1) = 3(2x+7)

20x + 5 = 6x + 21

14x = 16

x = 8/7

=> BK = 4(8/7)+1 = 39/7

Solve for W (W/-5) -4=-2

Simora [160]

Answer: $\Large\boxed{W=-10}$

Step-by-step explanation:

Given equation

$(\dfrac{W}{-5} )-4=-2$

Add 4 on both sides

$(\dfrac{W}{-5} )-4+4=-2+4$

$(\dfrac{W}{-5} )=2$

Multiply -5 on both sides

$(\dfrac{W}{-5} )\times (-5)=2\times(-5)$

$\Large\boxed{W=-10}$

Hope this helps!! :)
