Answer:
120 miles in 4.8 hours
75 miles in 5 hours
Step-by-step explanation:
Ship:
The number f(x) of miles a ship is from its destination x hours after starting a voyage is given by f(x) = 120 - 25x. This means, initially the ship is 120 miles away from its destination.
If the ship traveled 120 miles, then f(x)=0 (the ship will be 0 miles away from its destination) and
0 = 120 - 25x
25x = 120
x = 4.8 hours.
Submarine:
At x = 0 hours the submarine was 75 miles away
At x = 5 hours, the submarine was 0 miles away.
So, in 5 hours the submarine traveled 75 miles
3/8 + 5/2
=3/8 + 20/8
= 23/8
or
= 2 7/8
I = Prt
To find out what r is, you'll need to move P and t to the other side.
To get rid of multiplication, you divide.
I/Pt= Prt/Pt
Answer: I/Pt= r

Answer:=
=(x^2+4x)+(7x+28)
=x(x+4)+7(x+4)
