Answer:

3×(25-10)= 3×15=45.

However, if you are asking for the number which adds to 10 and makes 25, then the answer is 15.

g100num [7]

Answer:

1/2,  6/10,  2/3,  3/4

Step-by-step explanation:

we can convert each fraction to a decimal to compare:

2/3 = 0.666666 repeating

1/2 = 0.50

3/4 = 0.75

6/10 = 0.60

least to greatest:

1/2,  6/10,  2/3,  3/4

X-y = -10 2x+4y=22 substitution
Tema [17]

Answer:

[1]    x - 4y = 22

  [2]    2x + 5y = -21

Step-by-step explanation:

Solve equation [1] for the variable  x  

 

 [1]    x = 4y + 22

// Plug this in for variable  x  in equation [2]

  [2]    2•(4y+22) + 5y = -21

  [2]    13y = -65

// Solve equation [2] for the variable  y  

  [2]    13y = - 65  

  [2]    y = - 5  

// By now we know this much :

   x = 4y+22

   y = -5

// Use the  y  value to solve for  x  

   x = 4(-5)+22 = 2

I am sorry if I get it wrong.

Suppose that the functions g and f are defined as follows.
Sholpan [36]

Answer:

Following are the solution to the given question:

Step-by-step explanation:

Given:

\to g(x)= -3+2x^2 \\\\\to f(x)=9-6x

Calculating the value of (\frac{g}{f})(2):

\to (\frac{g}{f}) (2)= (\frac{g(x)}{f(x)}) \times  (2)

               =\frac{2x^2-3}{9-6x} \times 2\\\\=\frac{2\cdot 2^2-3}{3(3-2\cdot 2)} \\\\=\frac{2\cdot 4-3}{3(-1)}\\\\ =\frac{8-3}{-3}\\\\  =\frac{5}{-3}\\\\  = - \frac{5}{3}\\\\

x=- \frac{\sqrt{3}}{2} and x=\frac{\sqrt{3}}{2} are not in the domain.

Domain: x \belong (- \infty, -\frac{\sqrt{3}}{2})\cup (- \frac{\sqrt{3}}{2},  \frac{\sqrt{3}}{2} )\cup (\frac{\sqrt{3}}{2}, \infty)
