dexar [7]

Answer:

The train ride is 3.5 hours

Step-by-step explanation:

d = rt

We know the distance and the rate

420 = 120*t

Divide each side by 120

420/120 = 120t/120

3.5 =t

What is the y-value in the solution to this system of linear equations?

Alex787 [66]

This is the first line
$4x + 5y = - 12 \\ 5y = - 4 x - 12 \\ y = - \frac{ 4}{5} x - \frac{12}{5}$
$\binom{2}{ - 4} \: \: \: \: \: \: \binom{4.5}{ - 6}$
and this one is the second line:
$- 2 x + 3y = - 16 \\ 3y = 2x - 16 \\ y = \frac{2}{3} x - \frac{16}{3}$
$\binom{2}{ - 4} \: \: \: \: \: \: \binom{5}{ - 2}$
