Answer:

Yes, both equations will always work, but yes, at times it is more logical to use one over the other. for instance:

x-4y=6

x+4y=12

we see here that elimination would best fit:

x+x+4y-4y=6+12

or:

x=2y-3

7x+3y-81=23

substitute (2y-3) for x.

Also, once you have a single placeholder, put it ito quadratic form (ax^2+bx+c=0)

and use the quadratic formula:

x=(-b±sqrt(b^2-4ac))/2a

mixas84 [53]

Answer:

  (E) 22,400

Step-by-step explanation:

Let b represent the amount invested in bonds. Then b/4 is the amount invested in stocks, and the total amount invested is ...

  b/4 +b = 28000

  5/4b = 28000 . . . . . collect terms

  b = (4/5)(28000) = 22,400 . . . . . multiply by 4/5

Ski Mountain sells lift tickets. Ski Mountain Sale Packages Number of Lift Tickets Total Cost Package A 3 $30 Package B 5 $60 Pa
LenaWriter [7]

Answer:

Packages A and C

Step-by-step explanation:

To find the ratio between the number of lifts to the cost we first remove the $ symbol and find out how much 1 lift will cost per package.

Package A =  3 : 30

Package B = 5 : 60

Package C = 12 : 120

Package D = 16 : 120

Now let's break it down.

Package A = 30/3 = $10 per lift

Package B = 60/5 = $12 per lift

Package C = 120/12 = $10 per lift

Package D = 120/16 = 7.5 per lift

So now we are able to know which packages have the same ratio.

Package A and C cost $10 per lift.
