CL 2-107. Solve for w(show work): 6w - 5 + 8w - 2w - 3 = 9w - 24​
jekas [21]

Answer:

w = -16/3

Step-by-step explanation:

6w - 5 + 8w - 2w - 3 = 9w - 24​

Combine like terms

12w -8 = 9w -24

Subtract 9w from each side

12w -9w -8 = 9w -9w -24

3w -8 = -24

Add 8 to each side

3w-8+8 = -24+8

3w = -16

Divide each side by 3

3w/3 = -16/3

w = -16/3

Cos = adjacent / hypotenuse

cos 25° = 4 / AB

cos 25° • AB = 4 / AB • AB

AB cos 25° ÷ cos 25° = 4 ÷ cos 25°

AB = 4/cos 25°

AB = 4.41 (nearest hundredth)
