Answer:
<h2>
X = 4.5</h2>
Step-by-step explanation:
So we have two equations.
y=35x+40
y=40x+17.5
We want to find the coordinates in which they intersect.
BUT They never intersect, They are parallel to each other leaving us with a
NO SOLUTION
When you are trying to solve for x you want to get rid of the y's and simply put on your paper: 35x+40 = 40x+17.5
Then you distribute, in which I am not going to show because that too many steps lol. But you'll get:
x=4.5
The answer is 50%.
25 is the half of 50. Therefore, 25 is 50% of 50.
race entry costs 55, they use 15 of it to cover costs so they get 55-15 = 40 per entry
x = race entries
equation becomes 55000>= 40x +10000
45000>= 40x
x >= 45000/40 >= 1125
they need at least 1125 race entries to make $55,000
This is a problem in which the
percentage and the actual amount are both given. Only thing to do is convert
the percentage to amount.
3% of $600.85 = (3/100) * 600.85
= 1802.55/100
= 18.0255
= 18.03 dollars
So 3% of the amount $600.85 is $18.03.
I hope this was the answer you
were looking for and I have helped you in this matter. If you have understood
the procedure of doing this problem, then in future you can attempt such
problems by your own with absolute ease.
Let's call the fuel consumption of the first car "x" and the second car "y"
x + y = 35 is the total fuel consumed.
20x + 25y = 775 is the distance traveled.
Solve the two equations. Skipping a few steps, I get
5y = 75. Therefore y = 15. So y used 15 gallons of gas. Therefore x used 20 gallons.
20 gallons, 15 gallons.
