∠C = 180° - 45° - 65°
∠C = 70°
b/sin B = c/sin C
b/sin 65° = c/sin 70°
b = c/sin 70° × sin 65°
b = 20/0.9397 × 0.9063
b = 19.289
b = 19.3
        
             
        
        
        
Answer:
$325
Step-by-step explanation:
Time-share = $10 500
On first $10 000
,
Commission at 3 % = 0.03 × 10 000 = $300
On remaining $500,
Commission at 5 % = 0.05 ×      500 = <u>    25
</u>
                              Total commission = $325
Frank made $325 selling the time-share.
 
        
             
        
        
        
Answer:
-4
Step-by-step explanation:
In the formula y=mx+b the m is slope. the equation y=-4x-3 is in y=mx+b form. 
from there we can deduct that -4 is the slope
