Answer:

x=-\frac{70}{9}

Step-by-step explanation:

Isolate the variable by doing operations to both sides of the equation.  

The work is shown below:

\frac{5}{7} =\frac{10}{x} +2\\\\\frac{5}{7} - 2=\frac{10}{x} +2 - 2\\\\-\frac{9}{7} = \frac{10}{x}\\\\ -\frac{9}{7}*x = \frac{10}{x}*x\\\\ -\frac{9}{7}x = 10\\\\ -\frac{9}{7}x * (-\frac{7}{9})= 10 * (-\frac{7}{9}) \\\\x=-\frac{70}{9}

Mkey [24]
Sum of polynomials are always polynomials.

Note that despite it's name, single constants, monomials, binomials, trinomials, and expressions with more than three terms are all polynomials.
For example,
0, π sqrt(2)x, 4x+2, x^2+3x+4, x^2-x^2, x^5+x/ π -1
are all polynomials.

What makes an expression NOT a polynomial?
Expressions that contain non-integer or negative powers of variables, rational functions, infinite series.
For example,
sqrt(x+1), 1/x+4, 1+x+ x^2/2!+x^3/3!+x^4/4!+...., (5x+3)/(6x+7)
are NOT polynomials.

Can someone please help me with this question??

Answer:

In order of least money saved to most money saved: Katrina, Susan, Gabrielle, Savanna

Step-by-step explanation:

You can first change all of them to either percentages or fractions with the same denominator. I chose to use percentages. Thus Savanna's percentage of money saved would be 90%, Katrina would've saved 80% and Susan would've saved around 83%.

From here you just order from least to greatest.

Sindrei [870]
The answer is:  [C]:  " 3 " .
____________________________________
Explanation:
__________________________________
         4x - 1 = 2x + 5 ;  Solve for "x" ; 
__________________________________
 Subtract "2x" from each side of the equation; and add "1" to each side of the equation:
___________________________________________________
       4x - 1 - 2x + 1 = 2x + 5 - 2x + 1 ;
___________________________________________________
          2x = 6 ;
_________________________________
Divide EACH side of the equation by "2" ; to isolate "x" on ONE side of the equation;  and to solve for "x" ;
_________________________________
          2x / 2  =  6 / 2 ;
_________________________________
               x  =  3 .
_________________________________
The answer is:  [C]:  " 3 " .
