(x+10) + (x+20) = 180 since it's a linear pair. 

(y) + (y-40) = 180 since they're alternate exterior interior angles. 

Try solving for yourself. :)))

I believe you can do it, good luck.

Aww, thank you. :)))

67*88/3+100

First, let's do 67*88 = 5896

Then, let's do 5896/3 = 1965 1/3. 

Finally, let's add 100 to it. 1965 1/3 + 100 = 2065 1/3. 

I hope this helped. :)))

I think 10 is a recursive function because it has t(n-1) in the second part. I think it's also arithmetic since you aren't multiplying, but subtracting 1. 

I think 11 is geometric explict since you have the 4^x and there is no h(x) in theh right part. 

Stop reading and try figuring out 12 and 13 by yourself. :)))

I believe 12 is a arithmetic explict since you're doing 3/2n - 4, and there isn't g(n) in the right. 

Perhaps I've made a mistake since in 13 I think it's supposed to be geometric recursive?

Allie and Betty play a game where they take turns rolling a standard die. If a player rolls , she is awarded  points, where, \\ 0 & \text{ if }n\text{ is not a multiple of 2}. \end{array} \right.\]Allie rolls the die four times and gets a 5, 4, 1, and 2. Betty rolls and gets 6, 3, 3, and 2. What is the product of Allie's total points and Betty's total points?

The syntax seems to be a bit weird but I will try. 

(5+1)*(3+3) = 36?

Could you perhaps post the "figure shown?"

It might help with solving it. :))

If we define the amount he spent after his first item as x. 

x/2-10= 0

x/2 = 10

x = 20.

So he had 20 dollars after he bought the first item. :))

Oops, my bad, but it's great that you got the answer.  :))

Oh, my bad, but there's also diagonal squares.

Hello CubeyPenguin!

34/60+9/60*2 = 52/60 = 13/15 right?

I think there may have been a mistake.
