A team is playing a game and currently has 43 points. If they lose 56 points and then gain 13 points, what will their score be? Write an expression that models this situation and evaluate the expression.

(43 - 56) + 13 = 0 points

Step-by-step explanation:

We start with 43 points and loose 56 -- 43-56

then, 13 points are gained = (43 - 56) + 13

simplify and solve:

-13 + 13 = 0

*Note: you can write the expression without the brackets

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 : )
