Answer: Review terms, factors, and coefficients, and try some practice problems. ... Terms. Terms are single numbers, variables, or the product of a number and variable. ... What is a variable? Terms ... So in the expression: 12x+ 19y -1, is the constant -1 or 1? ... In the term "4x", 4 would be the coefficient in the algebraic expression.
 
        
             
        
        
        
<span><span>Molly: 105 x 05/02 = 42</span>
 Kim: 105-42</span> = 63
<span> Laura: 385-105 = 280 
           280 x 100/385</span><span> = 72%
Donc Laura obtient  72</span>% 
        
             
        
        
        
Answer:
<h2>17</h2>
Step-by-step explanation:
Use PEMDAS:
P Parentheses first
E	Exponents (ie Powers and Square Roots, etc.)
MD	Multiplication and Division (left-to-right)
AS	Addition and Subtraction (left-to-right)

 
        
             
        
        
        
You list the multiples of both numbers and see which number they share that is on each table
For example,
3,6,9,(12),15,18,21,(24)
4,8,(12),16,20,(24)
12 is the least common multiple of the numbers 3 and 4
        
             
        
        
        
6 bags × 24 balloons = the amount of round balloons
6× 24 = 144
3 bags × 36 balloons = the amount of long balloons
3 ×36=108
108 long balloons - 144 round balloons = number of more long balloons that round ones
 108-144=-36
He has -36 more long balloons that round ones
Or 36 more round balloons that long ones
