Yeah, these are tough.

When the plane is flying in the same direction as the wind,
the wind helps it cover ground faster.

Plane + Wind = 460 mph

When the plane is flying opposite to the wind, the wind makes it
cover ground slower.

Plane - Wind = 400 mph

================================

OK.  So far we have

Plane + Wind = 460 mph
Plane - Wind = 400 mph

Add the two equations, and you get

2 Plane + zero = 860 mph

Divide each side by 2:  Plane = 430 mph

Plug that into the first equation:     430mph + Wind = 460 mph

Subtract 430 mph from each side:  Wind = 30 mph

If the product of a number and -4 is subtracted from the number, the result is 3 more than the number. Find the number
lesya [120]

Answer: The number is 0.75 or 3/4

Step-by-step explanation:

let x = the number.

Now set up an equation: The product of a number (x) and -4 = -4x. So -4x is subtracted from the number - x.     x-(-4x)

Then, that equals 3 more than the number (x) = x+3

So the equation is x-(-4x)=x+3.

Then, solve the equation!

x-(-4x)=x+3

x+4x=x+3  (Distribute the negative to the parentheses)

5x=x+3  (Combine like terms)

4x=3  (Get the Xs on one side by subtracting x from both sides)

x=0.75 or 3/4  (divide by the coefficiant, 4, on both sides)

Five adult tickets and three child tickets for a movie costs £55. The cost of buying two adult tickets and three child tickets i
Allisa [31]

Answer:

  • adult £8
  • child £5

Step-by-step explanation:

If you look at the numbers you are given, you see that the first purchase has 3 more adult tickets than the second purchase, and its cost is £24 more. This means an adult ticket costs £24/3 = £8.

Two adult tickets will cost 2×£8 = £16, so three child tickets cost ...

  £31 -16 = £15

Each child ticket is then £15/3 = £5.

An adult ticket costs £8; a child ticket costs £5.
