1,2 liters of water = 1.200 millimeters so if he drinks 200 millimeters he has 1,000 millimeters left or 1 liter of water left
Alright.
For 7, you'll want to put congruent sides equal to each other, assuming they are parallelograms. So, you'll get the two equations:
3x+2=23
2y-7=9
Solve using GEMDAS/PEMDAS, and you'll get these answers.
3x+2=23
3x=21
x=7
2y-7=9
2y=2
y=1
For 8, you'll want to do the exact same thing, formatting the numbers to equal each other. You'll get these two equations:
3y+5=14
2x-5=17
Solving them would make:
3y+5=14
3y=9
y=3
2x-5=17
2x=22
x=11
For 9, you have to remember that the angle opposite of one angle in a defined parallelogram are congruent. Thus:
130=2h
5k=50
solve them and you get
h=65
k=10

Hope that helped. Good luck.
Answer:
Step-by-step explanation:
(fx+cd)/(x-f)=1/2
Cross multiplication,
2*(fx + cd) = 1 * (x-f)
2fx + 2cd = x - f
2fx - x = -2cd - f
x (2f - 1) = -2cd -f
x = (-2cd-f )/ (2f-1)
The fact that alternate interior angles MNR and QMN are congruent to each
other and vertical angles SNL and MNR are congruent to each other would help Kari prove that the measure of
angle QMN is equal to the measure of angle SNL. I am hoping that
