Answer: £225
Step-by-step explanation:
Let Sarah's amount be represented by x.
Since Caroline gets three times as much as Sarah, Caroline will get: 3x
Bridget gets twice as much as Caroline, therefore Bridget will get: 2 × 3x = 6x
Sarah = x
Caroline = 3x
Bridget = 6x
Total = x + 3x + 6x = 10x
Caroline's faction is 3/10. We then multiply the fraction by £750. This will be:
= 3/10 × £750
= 0.3 × £750
= £225
Caroline will get £225

= - 2 - 3
= - 5
 
        
                    
             
        
        
        
Answer: B =  +
 + 
Step-by-step explanation:
you need to get B alone so that would be subtracting everything around it
ab = -c + d
then you need to get that a away from it by dividing both sides by A
B =  +
 + 
 
        
             
        
        
        
Answer:
82
Step-by-step explanation:
let X = the number of hamburgers sold
let Y = the number of cheeseburgers sold  a combined total of 328 were sold
so: X + Y = 328
cheeseburgers = 3 times the number of hamburgers sold  
so: Y = 3X
substitute 3X into the equation for Y
X + 3X = 328
4X = 328
divide both sides by 4 to get the variable X by itself
X = 82
so: 82 hamburgers were sold Friday
