2x+8y=20;y=2
2x+8(2)=20
2x+16=20
-16 -16
-------------------
2x=4
x=2
The coordinate will be (2,2)! Hope that was helpful :)
Answer:
5 hours.
Step-by-step explanation:
5 hours * 60km = 300km in 5 hours.
A nonmember would have to go skating 11 times a year and a member would have to go skating 12 times a year.
They each paid $110.
I hope this is correct!
Good luck:)
To solve for x, first you need to isolate all x terms on the same side so:
you start with 5 + 4x = 54 - 3x
subtract 5 from both sides to get 5 onto the left side
now you should have 4x = 49 - 3x
now add 3x to both sides to get 3x onto the right side
now you should have 7x = 49
now that you have your x on one side you can solve this like a regular one step equation and divide both sides by 7
this leads you to your answer of x = 7
hope this helps!
The function is:
B ( t ) = 4 * e^(0.8 t)
4 * e^(0.8 t) = 400
e^(0.8 t) = 400: 4
e^(0.8 t) = 100 / ln
ln e^(0.8 t) = ln 100 ( and since: ln e = 1 and ln e^x = x * ln e )
0.8 t = 4.6
t = 4.6 : 0.8 = 5.76 ≈ 6
