Answer:
x = 1 , y = 1 and z = 0
Step-by-step explanation:
-2x+2y+3z=0    ------(1)
 -2x-y+z=-3     --------(2)
2x+3y+3z=5    ---------(3)
<u>To find the values of x,y and z</u>
(3) - (2)⇒ 2y + 4z = 2
y + 2z = 1   --------(4)
(1) - (2)⇒ 3y +2z =3   ---(5)
(5) - (4)⇒ 2y = 2
y = 1
Substituting the value of y in (4) we get z =0
Substituting the value of y and z  in (1) we get x = 1
Therefore x = 1 , y = 1 and z = 0
 
        
             
        
        
        
Answer:77 and 87
Step-by-step explanation:
7×6=42 + 5+7=35/\ 35+42=77(first outcome)
7×6=42 + 5×9=45/\42+45=87 (second outcome. 
 
        
             
        
        
        
20000*0.45 = 9000 in the bond
20000*0.15 = 3000 in the CD
20000*0.20 = 4000 in stocks
20000*0.029 = 580 in savings
A=9000(1 + 4.35%)^3 = 10,226.33
A=3000(1 + 2.90%)^3 = 3,268.64
A=4000 (1 + 8%) x (1 - 4%) x (1 + 6%) = 4,396.03 
A=580(1 + 4.35%)^3 = 4,545.04
Total value = 22,436.04
Gain = 22,436.04 - 20,000 = 2,436.04
