there are 27 more green cars than black cars in the parking lot. What percentage of the cars in the parking lot are green? What

Yanka [14]

Answer:

Black is 3.57%

Green is 96.43%

Step-by-step explanation:

Since 27 green than black

Let the black car be b

So green cars which 27 more than black means 27b

So to calculate the percentage of green we will have

27b/27b+b ×100

27b/28b ×100

Let's eliminate the b

27/28×100

2700/28

96.43%

So let's calculate for Black

b/27b+b ×100

b/28b ×100

Eliminate b

1/28 ×100

100/28

3.57%

Therefore the percentage for Black is 3.57% and for green is 96.43%

How do i check an equation for extraneous solutions?

Marina86 [1]

Example:

$\sqrt x(x+1)=0$

This suggests two solutions, $x=0$ and $x=-1$ .

However, upon plugging these solutions back into the equation, you get

$\sqrt0(0+1)=0(1)=0$

which checks out, but

$\sqrt{-1}(1-1)=0$

does not because $\sqrt x$ is defined only for $x\ge0$ (assuming you're looking for real solutions only). So, we call $x=-1$ an extraneous solution, and the complete solution set (over the real numbers) is $x=0$ .
