The correct answer is -1 and 1/2.

First, you need to divide 1/2 by -4/5. To do this, you multiply 1/2 by -5/4. You will get -10/8.

Then, you add -10/8 with -2/8 to get -12/8, or -1 and 1/2.

Two fewer than a number doubled is the same as the number decreased by 38. if n is "the number," which equation could be used to
Alona [7]
   
\displaystyle \\ 
\text{We use the following equation:} \\  \\ 
 \frac{n}{2} = n - 38 \\  \\ 
We solve for n: \\  \\ 
 \frac{n}{2} = n - 38 ~~\Big| \times 2 \\  \\  
n = 2 \times  n - 2 \times 38 \\  \\ 
n = 2n - 76 \\  \\ 
2n - n = 76 \\  \\ 
\boxed{n = 76} \\  \\ 
\text{Verification: } \\  \\ 
\frac{n}{2} = n - 38 \\  \\ 
\frac{76}{2} = 76 - 38 \\  \\ 
\boxed{38 = 38  ~~~ Correct }
