She originally started with 23.
We can tell this by working the equation backwards. Since she has 5 left and she had just given half to her brother, we know she had 10 a moment ago.
Before that, Mary had eaten a cookie. So we add 1 to the total and now have 11.
Before eating that cookie, she has given half to her sister, which would give her 22.
And before giving half to her sister, she had eaten the first one, which would give us 23 to start with.
The area of the triangle is 9.
The formula is BH/2
When you plug the numbers in
3•6/2
18/2
You get 9 as the result.

since ∠PRS is supplemental with ∠VUW , that is the two angles add up to 180 degrees, you know that TV is parallel with QS
then the order of the answer from top to bottom are
1
2
5
6
4
3
you have to distribute if I'm not wrong 2(3y+6)-30 (-4-y)
2x3y= 6y 2×6=12 -30×-4=120 -30×-y=30y
6y+12+120+30y
