At the beginning of the year, Wyatt had $40 in savings and saved an additional $14 each week thereafter. Julian started the year

with $20 and saved $19 every week. Let WW represent the amount of money Wyatt has saved tt weeks after the beginning of the year and let JJ represent the amount of money Julian has saved tt weeks after the beginning of the year. Write an equation for each situation, in terms of t,t, and determine the interval of time when Wyatt has more in savings than Julian.

Answer:

4 weeks

Step-by-step explanation:

Wyatt's equation:

t=14w+40

Julian's equation:

t=19j+20

Since both equations equal the same thing, or <em>t, we can equal them against each other as 1 equation</em>

14t+40=19t+20

(subtract 20 from both sides)

14t+20=19t

(subtract 14t from both sides)

20=5t

(divide both sides by 5)

t=4 weeks

Two trains are 500 miles apart when they first enter a collision course. If, after two hours, the distance between them is 300 m
MrRissso [65]

Answer:

The faster train goes 60mph

Step-by-step explanation:

s= speed

s+20 is the faster train.

Then you are given:

200/s+s+20=2

200=2*(2s+20)

4s+40=200

4s=160

s=40 is the slower train

40+20= speed of faster one

s=60 ;)

If the first chapter of a certain book is 16 pages long and makes up 4% of the book, how many pages does the entire book have?
galina1969 [7]
If 16 pages equal to 4%, how many pages will equal to 100%?

4/100 = 16/x
4x=1600
X= 400

So total pages should be 400.
