Answer:

4. 10mn - 35m

5. 8rs - 2r² + 16r

6. -4 (y +2)

7. -5p (p - 6q)

Step-by-step explanation:

For number four you basically times 5m to 2n and since it has different variables it would be 10mn ( keep the letters in alphabetical order) , then 5m times negative 7 would be '-35m'

For number five, it wants you to pass through the sign so negative times a negative always gives a positive so '-2r' times '-4s' would equal to '8rs', then -2r times r gives out -2r² since remember there are two same variables-in this case it is 'r' so to show there is two 'r' you put 'r squared' which is 'r²' and negative times a positive value gives negative.

For number 6, you take the Highest common factor out of the two values and in number 6 it would be -4 since there is a factor of -4 in both '-4' and '-8'. So if you take the -4 out of the bracket, there would be 'y' left and also '+2' since there is already a negative outside the bracket.

For number 7, similar to 6, take out the GCF/HCF which is -5 as it is factors in both of them. So -5 out of the bracket then 'p²' would be left and also if you divide 30 by -5 it would give -6 so the remainder would be -6pq. But if you see, you might notice there is both p in two of them so you can also take the p out with -5.

I know this is pretty long but if you don't understand have a read through them and if you still don't get please tell me what I did wrong. Thx

Maurinko [17]

Answer:

1000 runners

Step-by-step explanation:

Take total number of runners to be -----------x

90% of x managed to complete the marathon= 90/100 × x =0.9x

30% of those who completed the marathon were men= 30% × 0.9x

=0.3×0.9x= 0.27x

=270 men completed the marathon; this means

0.27x=270--------------------------------find x by dividing both sides by 0.27

x= 270/0.27

x=1000 runners
