Let 
x--------------> total volume of a glass
we know that
(4/7)x-70=(2/4)x------------> (4/7)x-70=(1/2)x--------> 2*(4/7)x-2*70=x
(8/7)x-140=x
<span>multiplied by 7 the expresion
</span>7*(8/7)x-7*140=7*x-----------> 8x-980=7x--------> x=980 cm³
the answer is 
<span>the total volume of the glass is 980 cm</span>³
        
                    
             
        
        
        
Answer:
See below
Step-by-step explanation:
Expand L side to get 
4n -12   -2n  <  -10 + 2n     simplify L side
2n -12   <  -10 +2n      subtract 2n from both sides
<u>-12 < -10 </u>    <===== so the equation is true for ALL n 
(-∞  ,  + ∞ ) 
 
        
             
        
        
        
X = 47
you subtract 133 from 180
        
             
        
        
        
Answer:
Matias divided 7.6 by 10 raised to the power of -2.
Step-by-step explanation:
Given : Matias preformed an operation with 7.6 and a number. He ended up moving the decimal point in 7.6 two places to the left.
To find :  Matias divided 7.6 by 10 raised to the power of ?
Solution : 
Matias preformed an operation with 7.6 and a number.
He ended up moving the decimal point in 7.6 two places to the left we have to multiply it with 0.01
i.e. 
So, Matias divided 7.6 by 10 raised to the power of -2.
