Answer:
15 weeks
The amount of money is  270
Step-by-step explanation:
You: 60 +14x
Sister: 120+10x
Set them equal to each other
60+14x = 120+10x
Subtract 10x from each side
60+4x= 120
Subtract 60 from each side
4x= 60
Divide by 4
4x/4 = 60/4
x = 15
15 weeks
The amount of money is 120+10*15 = 120+150 = 270
 
        
                    
             
        
        
        
Hi there! 
The formula for the area of a triangle is A = 1/2(b x h). Using the information provided, all we have to do is plug in what we know and solve! 
WORK: 
74 = 1/2(b x 9.14)
148 = b x 9.14 
b = 16.2 inches (approximately)
Hope this helps!! :)
