The first number is x
the second number is 2x-4
combine both numbers = 80
x+2x-4=80
3x-4=80
3x=84
x=28
one number is 28 and the other is 52.
x+y≤525 and 9x+5y≤1200 represents the scenario.
Step-by-step explanation:
Given,
Room for people at summer camp = 525 people
Maximum budget = $1200
Cost per adult = $9
Cost per camper = $5
It means that there cannot be spent more than $1200.
x represents the number of adults.
y represents the number of campers.
x+y≤525
9x+5y≤1200
x+y≤525 and 9x+5y≤1200 represents the scenario.

Answer:
Total amount Silas and Raja has at first = $252
Step-by-step explanation:
Let,
Amount Silas had = x
Amount Raja had = y
According to given statement;
x = 3y Eqn 1
x-84 = y+42 Eqn 2
Putting value of x from Eqn 1 in Eqn 2
3y - 84 = y+42
3y-y = 42+84
2y = 126
Dividing both sides by 2
Putting y = 63 in Eqn 1
x = 63(3)
x = 189
Total amount they had = 189 + 63 = $252
Hence,
Total amount Silas and Raja has at first = $252
T = seconds
M = number of miles
M=T/5
T = 5M
T=5(2miles)
T=10 seconds
