zalisa [80]

Answer:

 Number pencils Ava bought = 2

Explanation:

 Price of pen = 2 $

 Price of pencil = 1 $

 Total money spent = 12 $

 Let the number of pen be a and number of pencil be b.

  2 a + b = 12   -----------------------------------Equation 1

 We have, she bought 3 more pens than pencils

   a - b = 3   --------------------------------------  Equation 2

  Equation 1 +Equation 2,  

           2 a + b +  a - b = 12 + 3

                 3a = 15

                   a = 5

   Substituting in  equation 2

                 5 - b = 3

                b = 2

    Number pencils Ava bought = 2

Solve the quadratic equation. <br><br> 3x^2 - 5= 70<br><br> (Please explain steps)
Svet_ta [14]
Simplifying
3x2 + -5 = 70

Reorder the terms:
-5 + 3x2 = 70
Solving
-5 + 3x2 = 70

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '5' to each side of the equation.
-5 + 5 + 3x2 = 70 + 5

Combine like terms: -5 + 5 = 0
0 + 3x2 = 70 + 5
3x2 = 70 + 5

Combine like terms: 70 + 5 = 75
3x2 = 75

Divide each side by '3'.
x2 = 25

Simplifying
x2 = 25

Take the square root of each side:
x = {-5, 5} and that’s it.
