Answer:

x = 48/7

Step-by-step explanation:

There's two good ways to do this problem.

Option 1:

Translate "x varies directly as y" into the equation y=kx

Then you have to find k. After you "reset" your y=kx equation, fill in k and then solve for x. See image.

Option 2:

Translate "varies directly" into a proportion, which is two fractions equal to each other:

x/y = x/y

Fill in the three numbers given and cross multiply and solve to find the fourth number. See image.

A. write an expression for the total cost of three types of tickets .

babymother [125]

If youre writing an exprssion all you need to do is make variables and multiply by the given number A, C, and S will be our variables.
2A + 3C + 1S = Total cost for andrews family

4A + 2C = Total cost for Spencers family

Now, Does 2A + 3C + 1S = 4A + 2C

lets say A = 5 , C = 3 , and S = 2
2(5) + 3(3) + 1(2) = 4(5) + 2(3)
10 + 9 + 2 = 20 + 6
21 = 26

if this is your example then No, the spencers family spent more than the andrews family, youll have to do the math differently and may come up with a different answer if you were given values that you didn't give us, but this is how its done :)

Hope this helps!

saveliy_v [14]

Answer:

Step-by-step explanation:

First, you need to find the fraction of the passengers who are not senior citizens. Add 1/5 and 2/3 to get 13/15.

This means that 13/15 of the passengers aren't senior citizens and 2/15 of the passengers are senior citizens.

Hope i helped!
