Answer:

she bought 8 coach, 2 first-class

Step-by-step explanation:

let x = number of coach tickets

equation I used:  320x + 960(10 - x) = 4480

                            320x + 9600 - 960x = 4480

                            -640x = -5120

                             x = 8

This is a false statement.

When you are solving using square roots, you need to be aware that answers can be both positive and negative. When we solve this, you see there are two possible answers.

x^2 - 9 = 0

x^2 = 9

x = +/- 3

While 3 is an answer, so is -3. If we square either of those numbers, we get 9, which will satisfy the equation.

polet [3.4K]

Answer:

46 miles per hour

ِAn hour has 60 minutes. In 60 minutes, there is four 15 minutes (4*15 = 60).

So, if it travelled 11.5 miles in 15 minutes, in an hour, it travelled 11.5 * 4 = 46 miles per hour.
