Answer:
x < 3
Step-by-step explanation:
86 cause 92-6=86 when you subtract .
Answer: -2
Step-by-step explanation:
slope= y2-y1 / x2-x1
m= -3-3 / 2-(-1)
m= -6 / 3
m= -2
Answer: 2/3
Step-by-step explanation:
3(1+2t)=3t+5
3+6t=3t+5
6t-3t=5-3
3t=2
t=2/3
First let us calculate for the total time of the travel
using the formula:
time = distance / velocity
time = 90 miles / 40 mph
time = 2.25 hours
Next, we calculate for the total gallons of fuel that is
theoretically required:
theoretical amount needed = 90 miles / 24 mpg
theoretical amount needed = 3.75 gallons
The difference of the actual and theoretical amount is the
amount which leaked:
amount leaked = 8 gallons – 3.75 gallons
amount leaked = 4.25 gallons
Therefore the amount of gallons leaked per hour is:
amount leaked per hour = 4.25 gallons / 2.25 hours
<span>amount leaked per hour = 1.89 gallons / hr</span>
