Answer:3/4
Step-by-step explanation:
Multiply 1/6 by 2 to get 2/12 and then add that to 7/12 and get 9/12 
If you simplify that you end up with 3/4
 
        
                    
             
        
        
        
Answer:
30 gallons of 6% milk, and 45 gallons of 1% milk.
Step-by-step explanation:
x=quarts of 6% butterfat
<h2>First, write an equation.</h2>
0.06x+0.01(75-x)=0.03*75
<h2>Multiply both sides by 100.</h2>
0.06x*100+0.01*100(75-x)=100*0.03*75
<h2>Simplify</h2>
6x+75-x=3*75
6x+75-x=225
<h2>Solve</h2>
5x=225-75=150
5x=150
x=30 
75-30=45
So, we need 30 gallons of 6% milk, and 45 gallons of 1% milk.
 
        
                    
             
        
        
        
X = 180 - (90 + 47)
x = 180 - 137
x = 43
answer angle x = 43
        
                    
             
        
        
        
T = state income return (without sales tax)
106% of t = 4960.80
AKA
1.06t = 4960.80 --> Divide both sides by 1.06 to find the state income return without sales tax
t = 4680 
Subtract t from the state income return with sales tax.
4960.80 - 4680 = 160.80
<u>She paid $160.80 in sales tax.</u>
