Answer:
Step-by-step explanation:
<em>Set up equations (L= Lisa; M = Maria; A = April; J = Jim)</em>
L = 12M
A = 2J
<em>Substitute x for Maria and 6x for Jim</em>
L = 12x
A = 2(6x) = 12x
<em>So, you get:</em>
Maria = x
Jim = 6x
Lisa = 12x
April = 12x
 
        
             
        
        
        
2/7 ( k+5/8) = 2 and 2/7
2/7 (k+5/8) = 16/7     |multiply by 7
2(k+5/8) = 16     |divide by 2
k+5/8 = 8     |subtract  5/8
k=8-5/8 = 7 and 3/8 = 27/8 = 7.375 
        
             
        
        
        
Answer:
A radical equation is an equation in which a variable is under a radical. To solve a radical equation: Isolate the radical expression involving the variable. If more than one radical expression involves the variable, then isolate one of them.

The possible outcomes for the coin is 2 out of 1 since a coin has 2 sides the coin may only land on 1 side but the chances are between both sides having a 50/50 chance to land on either side.
