Oh fun! I can’t do the whole page since I have to for my own but it’s pretty easy trust me! For example 3 x 10*3<—— (that’s supposed to be a smaller 3.) first do 10 x 10 x 10= 30 and do 30 x 3= 90! And boom easy you have your answer! Hope that helps!
        
             
        
        
        
Answer:
53$
Step-by-step explanation:
They tell you the equation of how much the coin is worth after x amount of years 
Step 1: Substitute x=19 into the equation y=2x+15
y = 2(19) + 15
Step 2: Solve for y
y = 2(19) + 15
y = 38 + 15
y = 53
Therefore the coin is worth 53 dollars after 19 years
 
        
                    
             
        
        
        
We must find the common denominator.
LCM(6, 3) = 6

or other method of calculating the difference

 
        
             
        
        
        
150+150+2x=960 (width+width+2 length=perimeter)
subtract 300 from each side
2x=660
divide by 2
x=330
the length is 330 ft
        
             
        
        
        
Answer:
$0.75
Step-by-step explanation:
Given
Normal price - $3.70
If Hamburger is on  sale for 20% off the normal price
The amount that can be saved will  be 20% of $3.70
Amount that can be saved = 20/100 * 3.70
Amount that can be saved  = 1/5 * 3.70
Amount that can be saved  = 3.7/5
Amount that can be saved  = 0.75
Hence the Amount that can be saved on $3.70 is $0.75
