Answer:
7x50 will have one 0 !
Explanation:
I usually just take the zero out and multiply the other numbers (7x5). So, seven times five is 35, then now i add the zero! 
Step by step explanation:
7x5∅
7x5=35
Since I took away the zero, I will now add it back after I get the answer.
35←0
350
ONE ZERO!

Money Required for making 1 Sandwich that is Cost Price of 1 Sandwich = S Dollar
Selling Price of 1 Sandwich = 20 % more than Cost Price S
                     = S + 20 % of S
                      = 
                      =$ 1.20 S
                       = $(S + 0.20 S)
Selling Price of 73 Sandwiches = $ 73 (S + 0.20 S)
 The expression $73(S+0.2 S) →→  Selling Price of 73 Sandwiches          
 
        
                    
             
        
        
        
Answer:
see explanation
Step-by-step explanation:
The 2 marked angles are vertical and congruent, thus
24x = 23x + 5 ( subtract 23x from both sides )
x = 5
Thus angles = 24 × 5 = 120°
 
        
             
        
        
        
P  140 units
A  1200 units^2
Step-by-step explanation:
The length of the rectangle is 20 to -20 = 20 - -20 = 40 units
The width of the rectangle is 20 to -10 = 20 - -10 = 30 units
The perimeter is given by
P = 2 ( l+w) = 2 (40+30) = 2 (70) = 140 units
The area is given by
A = lw = 40*30 = 1200 units^2
