Using the information provided, you would do 17/.85 to find the total amount. Subtract that quotient from 17 and you will get how much your friend spent.
Answer:
The resulting equation is
x^2/4+16x^2/9=1
Step-by-step explanation:
The given equations are:
3y=12x eq(1)
x^2/4+y^2/9=1 eq(2)
We need to isolate variable y in equation 1
Divide both sides of the equation with 3
3y/3 = 12x/3
y = 4x
Now, substitute the value of y=4x in second equation
x^2/4+y^2/9=1
x^2/4 + (4x)^2/9 = 1
The resulting equation is
x^2/4+16x^2/9=1
Answer:
For the extra credit question just plant the dotss and if its a square then do what it sais
Step-by-step explanation:
We see this same problem pop up here on Brainly every
couple of months. Nobody yet has ever given us enough
information to answer it.
There's no information here that we can use to find out the
weight of any of the cattle placed on feed. There must be
some more information BEFORE this.
Maybe it's in the previous question in the book or on the
homework sheet, and nobody who posts this question ever
includes the information from the question before it.
We know, speed = distance / time
Here, distance = 1000 Km
t = 7 5/6 = 47/6 hours
S = 1000 * 6 / 47
S = 6000 / 47
S = 127.65 Km/h
[ Please check your distance would be 100 Km i guess, if yes, then your answer will be B) 12 Km/hr ]
Hope this helps!
