Answer:

Richard gets: £9

Andrew gets: £21

Step-by-step explanation:

To get the value of 1 part we have to add the total number of parts (3+7) and then divide them by the sum (30) 30/10 = 3 so we know 1 part is £3

Thus Richard gets: £3*3 = £9

And Andrew gets: £3*7 = £21

7+3 = 10
30/10 = 3
3(3) = 9
7(3) = 21

richard gets 9
andrew gets 21

Solve. Note the equal sign. What you do to one side, you do to the other. Remember to follow PEMDAS.

First, distribute 5 to all terms within the parenthesis

5(w - 1) = (5)(w) + (5)(-1) = 5w - 5

Next, simplify. Combine like terms

5w - 5 - 2 = 5w + 7

5w - 7 = 5w + 7

Next, isolate the variable. Add 7 to both sides, and subtract 5w from both sides

5w (-5w) - 7 (+7) = 5w (-5w) + 7 (+7)

5w - 5w = 7 + 7

0 = 14 (Untrue).

The sum of three prime numbers (other than two) is always odd.
grandymaker [24]

Step-by-step explanation:

The statement in the above question is True.

Sum of three prime numbers (other than  two)  is always odd.

Going by Christian Goldbach number theory ,

  • Goldbach stated that every odd whole number greater than 5 can be written as sum of three prime numbers .  

 Lets take an example,

  • 3 + 3 + 5 = 11
  • 3 + 5 + 5 = 13
  • 5 + 5 + 7 = 17

Later on in 2013  the Mathematician <u>Harald Helfgott</u> proved this theory true for all odd numbers greater than five.

Use the equation p = 831 where p = pressure and
Inga [223]

Answer:

The lower the volume, the higher the pressure.

Step-by-step explanation:

Volume and pressure are inverse to each other -- so the more pressure, the less volume, and vice versa. Think of it like this: if you were squished into a tiny room, there would be a lot of pressure on you, and not a lot of volume to move in!

You can also think of it numerically. The higher the V in that equation (the higher the denominator) the lower the p in the equation.
