Answer:
4.) y=x-16
Step-by-step explanation:
Here,
y=4,
x=20
Now,
putting the value of x and y.
or, 4=20-16
or, 4+16=20
∴20=20
Sonia saves a lot of water. To figure this out, you plug the number 8 into the equation, replacing it with the variable x. y = 3(8). Therefore, y=24. To find out how much water she saves, you have to also figure out how much water she was using for 8 minutes with the other shower head, the one that wastes the water. Since it dispenses 12 gallons per minute, you multiply that by 8 minutes and get 96. Subtract 24 from 96 and get 72. Which I think is your answer. Then again, I'm in high school so I most likely am wrong.
Answer:
f
Step-by-step explanation:
You know that:
X is congruent to angle Z which means they are the same size
the straight line below is equal to 180
Y is a right angle so its equal to 90
So that means:
if x and z are equivalent that means they are equal to 2x essentially
and if you add 90 you will get the total of the line
Hope this helps!!! :)
