Answer:
x = 1.8
Step-by-step explanation:
2 ( 4x-3) - 8 = 4-2x
Distribute
 8x -6 -8 = 4- 2x
Combine like terms
8x - 14 = 4 - 2x
Add 2x to each side
8x - 14 +2x = 4-2x+2x
10x-14 = 4
Add 14 to each side
10x-14+14 = 4+14
10x = 18
Divide by 10
10x/10 = 18/10
x = 1.8
 
        
             
        
        
        
Answer:
4(5)+5y=20          20+5y=20 then subtract the 20 with other 20= 0
5y/5=0/5                               y=0

Answer:
Probability that the cost will be less than $500 is 0.95994 .
Step-by-step explanation:
We are given that Money magazine reported that a visit to a hospital emergency room for something as simple as a sore throat has a mean cost of $348 with a standard deviation of $87.
Let X = cost of a hospital emergency room visit for this medical service
So, X ~ N( )
)
The standard normal z score distribution is given by;
               Z =  ~ N(0,1)
 ~ N(0,1)
(a) Probability that the cost will be less than $500 = P(X < $500)
     P(X < 500) = P(  <
 <  ) = P(Z < 1.75) = 0.95994 {from z table}
 ) = P(Z < 1.75) = 0.95994 {from z table}
Therefore, the probability that the cost will be less than $500 is 0.95994 .
                                                
 
        
             
        
        
        
Answer:
1.8 gallons would be used. 
Step-by-step explanation:
TOTAL AREA TO BE PAINTED:
      2 x 10 x 20  +   2 x10x 16 = 720 ft2
720 ft2 / 400 ft2 /gal = 1.8 gal
