Answer:

Tootsie = 10

Jolly Ranchers = 12

Step-by-step explanation:

t= .03

j= .05

You would want 10 tootsies and 12 jolly ranchers

t x j= .90

Insert the previous term into the answer and you can always find it.

Answer:

  • 10 tootsie rolls, 12 jolly ranchers

Step-by-step explanation:

Let tootsie rolls be t, jolly ranchers be r.

<u>The cost of them is 3t and 5r and we have following equations:</u>

  • t + r = 22
  • 3t + 5r = 90

<u>Solve the system by elimination, multiply the first equation by 3 and subtract from the second equation:</u>

  • 3t + 5r - 3t - 3r = 90 - 66
  • 2r = 24
  • r = 12

<u>Find the value of t:</u>

  • t = 22 - 12 = 10

HELP HELP HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Arrange the functions in ascending order, starting with the function t
san4es73 [151]
If x is squared, that will be biggest by the end because it gets bigger the quickest. x^2 + 4 is always 4 greater than x^2, no matter what the value of x is.

5x+3 is always 3 greater than 5x also.

Besides that, you can rank them based on their slopes (5x < 7x < 8x, etc.)

So,
5x
5x + 3
7x
8x + 3
x^2
x^2 + 4

You can also just say “eventually” means that they’re asking to find the values of each when x is really big. so just choose x=100, and plug that into each one.

So, to check that order:
5(100) = 500
5(100) + 3 = 503
7(100) = 700
8(100) + 3 = 803
(100)^2 = 10,000
(100)^2 + 4 = 10,004

Those are in ascending order, so that must be the right order!
