Divide. 8 2/5÷(−2 1/5) enter your answer as a mixed number, in simplified form, in the box.


15 !

Step-by-step explanation:

= 42 ÷   -11

   5         5

flip the -11/5 to -5/11

= 42 x  - 5

   5         11

=  - 42 * 5

       5 * 11

= - 42

     11

convert to mixed number:

-42/11 = - 3

42 - (11*3) = 9

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
