At a football game a vender sold a combined total of 240 sodas and hot dogs the number of sodas sold was three times the number

Sidana [21]

Answer:

60 hot dogs and 180 soda

Step-by-step explanation:

Soda was sold 3 times the number of hot dogs, and there were 240 in total.

So the equation would be:

3x + x = 240

3x being the number of soda and x being the number of hot dogs which like i sad earlier adds up to 240.

3x + x = 240

4x = 240

x= 60

60 being the amount of hot dogs and 3 time of soda would be 180 and adding them both up would be 240

Solve x2 – 4x – 9 = 29 for x.

Irina-Kira [14]

$x^2 - 4x - 9 = 29 \\ x^2 - 4x - 9 - 29 = 0 \\ x^2 - 4x - 38 = 0 \\ x= \frac{-b \pm \sqrt{ b^{2} -4ac} }{2a} 
$ ; where a = 1, b = -4 and c = -38
$x= \frac{-(-4) \pm 
\sqrt{ 
(-4)^{2} -4 \times 1 \times -38} }{2 \times 1} \\ = \frac{4 \pm \sqrt{ 16 +152} }{2} \\ =\frac{4 \pm \sqrt{ 168} }{2} \\ =\frac{4 \pm 
2\sqrt{42} }{2} \\ 
=2+\sqrt{42} \ or \ 2-\sqrt{42}\\=8.48 \ or \ -4.48$
