salantis [7]

Answer:

125 adults

175 children

Step-by-step explanation:

3900=8c+20a

300=c+a

c=300-a

substitute

3900=8(300-a)+20a

reduce

3900=2400-8a+20a

1500=12a

a=125 adults

c=300-a

c=300-125

c=175 children

Park Crest Middle School has a population of about 400 Eighth Graders.

Kobotan [32]

Answer:

$10^3$ times

Step-by-step explanation:

Given

Let

$P \to$ Park Crest Middle School

$T \to$ Total

So, we have:

$P = 400$

$T = 406240$

Required

Determine the number of times T is greater than P

This is calculated by dividing T by P.

i.e.

$n = \frac{T}{P}$

So, we have:

$n = \frac{406240}{400}$

$n = 1015.6$

Approximate

$n \approx 1000$

As a power of 10, we have:

$n = 10^3$

Which ordered pair is a solution to the system of linear equations -4x+y= 8 and X-5y=17?

iren [92.7K]

C is the correct answer.
Plug the x & y values for x and y in the equation and you'll get true statements. For example:
-4(-3) -4 = 8
12-4=8

And in the second equation:
-3 -5(-4) = 17
-3 +20 = 17
