What number is to 100 as 4 is to 78

vitfil [10]

Hello,

4 is to 78 as x is to 100, we write it as a ratio:

$\frac{4}{78}= \frac{x}{100} \\ \\ x= \frac{100*4}{78} \\ \\ \boxed{x= \frac{200}{39}=5.13}$

Please help me with this quadratic equation question! I always give out 5 stars, thanks and brainliest to people that help me wi

Answer:

$p=25,\\q=12$

Step-by-step explanation:

In $(ax+b)(cx+d)=acx^2+bcx+dax+bd$ , notice the third term of the quadratic in standard form is formed entirely by $b\cdot d$ .

Therefore, in $12x^2 - 13x - 7175 = (x-p) (qx + 287)$ :

$-p\cdot287=-7175,\\-p=\frac{-7175}{287},\\p=\fbox{$25$}$ .

Now that we found $p$ , we must find $q$ . The first term of the quadratic in standard form is formed entirely by $ax\cdot cx$ . Therefore:

$1\cdot q=12, \\q=\fbox{$12$}$ .
