8 0

Answer:

48 old houses

Step-by-step explanation:

First of all, every 4 new houses, there's 8 old houses. That's 4x8, therefore, if there are 8 new houses, that's 8x2, which is 16. Based on this information, this means that if there are 24 new houses, then you would have to multiply 24 by 2 to find the amount of old houses. 24x2=48. VOILA! You're done. :3

Given the equation:

Alisiya [41]

Answer:

x = 1 and x = $\frac{-4}{5}$

Step-by-step explanation:

In this equation, a=5, b=-1, c=-4.

Plug these into the quadratic formula:

x = $\frac{1+\sqrt{-1^{2}-(-4)(5)(-4) } }{2(5)}$ and x = $\frac{1-\sqrt{-1^{2}-(-4)(5)(-4) } }{2(5)}$

Now, simplify the equations:

x = $\frac{1+\sqrt{81} }{10}$ = $\frac{1+9}{10}$ = $\frac{10}{10}$ = 1

and

x = $\frac{1-\sqrt{81} }{10}$ = $\frac{1-9}{10}$ = $\frac{-8}{10}$ = $\frac{-4}{5}$
