<h2>Numerical expressions are numbers and signs, like below.  The following are some examples of numerical expressions, numerical expressions do not use letters.
4 + 20 – 7, (2 + 3) – 7, (6 × 2) ÷ 20, 5 ÷ (20 × 3)  
An algebraic expression uses letters and it says you to find "x/y/z".

Answer:
Step-by-step explanation:
Let equal sides of an isosceles triangle = a inches
Base =  inches
 inches
Perimeter  = 32 inches
a + a +  = 32
 = 32

Subtract 2 from both sides

a = 12 inches
base = 
         = 6 + 2
Base = 8 inches
 
        
             
        
        
        
 6 one-dollars = $6 15 five-dollars = $75 9 ten-dollars = $90 Add them
all up to get $171, so that is correct. Add the number of one-dollar
bills and the number of ten-dollar bills together. 6 + 9 = 15, which is
the number of five-dollar bills, so that is correct as well. Add all the
numbers of bills together, 6 + 9 + 15 = 15 + 15 = 30.
