Ineed with starting the equation or getting the answer

The costs per year U(x) and S(x) when x represents the number of fitness classes attended:

1) U(x) = 250 + 3.5 * x

2) S(x) = 400 + 2 * x

3) Set the costs of both gyms to be equal and solve for x:

U(x) = S(x)

250 + 3.5 * x = 400 + 2 * x

1.5 * x = 150

x = 100

The costs for both fitness gyms are the same when you attend 100 classes. The costs are:

U(100) = 250 + 3.5 * 100 = 250 + 350 = 600

S(100) = 400 + 2 * 100 = 400 + 200 = 600

Both gyms will cost $600 if you attend 100 classes.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
