Answer:

28 girls

Step-by-step explanation:

Given girls : boys ===> 7 : 12

i.e.

fraction all children who are girls = 7 / (7 + 12) = 7 / 19

fraction all children who are boys = 12 / (7 + 12) = 12 / 19

given that there are 76 children

number of girls = fraction of all children who are girls x total number of children

= 7/19 x 76

= 28 girls

Consider this quadratic equation. 2x2 − 1 = 3x + 4 Which equation correctly applies the quadratic formula?

Mariulka [41]

Answer:

$\frac{-(-3)+-\sqrt{(-3)^2-4(2)(-5)}}{2(2)}$

Step-by-step explanation:

Quadratic formula: $\frac{-b+-\sqrt{b^2-4ac} }{2a}$

$2x^2-1=3x+4\\\\2x^2-3x-5=0\\\\\\frac{-(-3)+-\sqrt{(-3)^2-4(2)(-5)}}{2(2)} \\\frac{3+-\sqrt{9+40} }{4}$

$x = \frac{3+-7}{4}$

In the equation 9 more than 3 times a number is -6, what does a number equal

atroni [7]

So 9 more than 3 times a number, would be:
9+(3x)=-6
then you would solve
subtract 9 from 9 and 9 from -6
you get 3x=-15
divide by 3 on both sides
x=-5
