Work Shown:

9 trains headed north

5+4+9 = 18 trains total

P(north) = (# of north)/(# total) = 9/18 = 1/2

Answer:

17minutes 10sec

Step-by-step explanation:

Total time running and walking

= time ran + time walked

= 11 minutes 24 sec + 5 minutes 48sec

= 16minutes 70sec

( now we know 60 sec = 1 min) so..

= 17minute 10sec

Answer:

General equation of a line:

[tex]y = mx + b[/tex]

then express in that form:

[tex] \frac{x}{2} - y + 6 = 0 \\ \\ - y = - \frac{x}{2} - 6 \\ \\ { \boxed{ \boxed{y = \frac{1}{2} x + 6}}}[/tex]

Step-by-step explanation:

-3x + 6y = 18

-3x = 6y+14

a) the slope of the 1st equation = -(-3)/6 = ½

b) the slope of the 1st equation = -3/6 = -½

c) they are niether parallel nor perpendicular

#1

slope=1/2

#2

slope=-1/2

#3

Neither

The amount of money used for scholarship and the fraction of the estate gotten by Miss Maple are :

The entire fraction of the estate = 1/1

Fraction given to children = 2/3

Fraction left = Total - fraction given to children

Fraction left = 1/1 - 2/3 = 1/3

For scholarship :

1/5 of fraction left :

1/5 of 1/3 = 1/5 × 1/3 = 1 /15

Fraction Given to grand children :

1/5 - 1/15 = 2/15

Amount of money used for scholarship :

1/15 × 8424000 = $561,600

B.)

Since There are four grand children and it was equally shared among them:

Miss Maple is one of the grand children:

Fraction each grandchild gets is :

2/15 ÷ 4

2/15 ÷ 4/1

2/15 × 1/4 = 2/60 = 1/30

Hence, miss Maple will get 1/30

let x represent the number

7(x) + 5 = 7 - x

so we now group like terms

7x + x = 7 - 5

8x = 2

we now divide through by 8

Step-by-step explanation:

As I write this Reiner is standing at my side. He knows this is a love letter but he’s still sneaking glances. Honestly it’s no wonder the creep is still single.

That said, he did give me his word that he’d deliver this letter to you. He says he owes me for the time I doubled back to save him.

I’m sorry about that. I never would have imagined myself choosing those two over you.

I’m gonna die soon,

but I’ll die without regrets.

Or that’s what I’d like to say.

Truth is, I do have one.

It's that I never got to marry you...

With love, Ymir.
