Answer:
4.969696 hours
Step-by-step explanation:
The distance traveled is shown through the following equations
Distance = velocity * time
This means that
4100=velocity*4
This means that ariplane 1 travles at 1025 km/hr
We can then subtract 200 from this to find that airplane two travels at a speed of 825 km/hr
Now we need to find how long it takes for that plane to travel 4100
So using the same equation
4100=825*time
Divison will tell us that the answer is around 4.9696 hours which is pretty much 5
Carla can babysit for 5 hours and tutor for 7 hours or babysit for 8 hours and tutor for 5.5 hours
<h3>How to graph the inequality?</h3>
Let x represents hours babysitting and y represents hours tutoring
So, we have:
Earnings = Rate of babysitting * x + Rate of tutoring* y
This gives
Earnings = 5x + 10y
He wants to earn at least $95.
This means that:
5x + 10y ≥ 95
See attachment for the graph of the inequality
From the attached graph, two possible solutions are: (5, 7) and (8, 5.5)
This means that Carla can babysit for 5 hours and tutor for 7 hours or babysit for 8 hours and tutor for 5.5 hours

The answer is B because you have to do the opposite which means you have to subtract -9-2=-11
Answer: A.4Runner cost more for $11.02
B.Cost of fuel for Elentra: 3.75*3.59=$13.46
Cost of fuel for 4Runner : 6.818*3.59=$24.48
Step-by-step explanation:
A.Find how many gallons 4Runner spends on 150 mile trip.
use proportion
22:1=150:x
22x=150
x=150/22
x=6.818 gallons
Cost of fuel for 4Runner : 6.818*3.59=$24.48
Calculation for Elentra:
40:1=150:x
40x=150
x=150/40
x=3.75 gallons
Cost of fuel for Elentra: 3.75*3.59=$13.46
Cost of fule for 4Runner-Cost of fuel for Elentra=24.48-13.46=$11.02
4Runner cost more for $11.02
B.Cost of fuel for Elentra: 3.75*3.59=$13.46
Cost of fuel for 4Runner : 6.818*3.59=$24.48
The thing true about that is that we can use the distributive property to simplify it.
4(9+6) = 4*9 + 4*6 = 36 + 24 = 60
