Answer:

x=-3

Step-by-step explanation:

So, we are given:

\frac{3}{x}=\frac{4x+3}{x^2}

First, we should immediately rule out 0 as an answer. This is because the if x=0, the equation would be undefined.

x\neq 0

Now, cross multiply.

3(x^2)=x(4x+3)

3x^2=4x^2+3x

Divide everything by x (and we can do this safely because we already know x cannot be equal to zero).

3x=4x+3

-x=3

x=-3

We didn't run into any possibilities for extraneous solutions.

On Map 1, which has a scale of 1:25000, length of road is 5.5cm and the area of a park is 1.4cm2
Zolol [24]

Answer:

50 km

Step-by-step explanation:

So the map has a scale of 1 cm: 20 km. Next, you look at how far they are apart and see if the scale and the distance on the map are the same measurement. In this case, they are both centimeters so they stay the same. Then, all you do is multiple the real size, 20 km, by

2.5

1

. Then, 20 x 2.5=50. So the answer is 50 km
