6/2(1+2)+1-1+1-1+1-1​

SO do the one in the paranthesis first.

So we will get 3 in the () section

6/2(3)+1-1+1-1+1-1

:/

9

= 6/2*(1+2)+1-1+1-1+1-1

= 6/2*(3)+1-1+1-1+1-1

= 6/2*3+1-1+1-1+1-1

= 3*3+1-1+1-1+1-1

= 9+1-1+1-1+1-1

= 10-1+1-1+1-1

= 9+1-1+1-1

= 10-1+1-1

= 9+1-1

= 10-1

= 9

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
