Answer:
291 .1
Step-by-step explanation:
80.2 + 91.6 + 123 + 204.7 + x = 790.6
790.6 - 499.5 = 291. 1
 
        
             
        
        
        
Answer:
30 dollars
Step-by-step explanation:
packages-$12.36 x 2=24.72
broccoli-$1.98/2=.99
milk-$3.49
$24.72+.99=25.71
$25.71+$3.49=29.20
$29.20+.80=30.00
she payed with $30.00
 
        
             
        
        
        
A unit rate will always end up having one as its denominator so divide 305 by 5 which is 61 rotations/1 minute.
        
             
        
        
        
Step-by-step explanation:
ax2 + bx + c = 0 
x12 = (-b ± √D) / 2a , D = b2 - 4ac . 
5x2 + 7x + 3 = 0 
a = 5 , b = 7 , c = 3 
D = 49 - 60 = - 11 , x1 = (-7 - i √11) / 10
 x2 = (-7 + i √11) / 10
