Answer:

C

Step-by-step explanation:

b) Assume AC = CE

d) Since C is the MP of BD,

BC = CD

e) AC = CE,

AC - BC = CE - CD

c) AB = DE which is not true

a) Hence our assumption was

incorrect that AC = CE. Therefore,

AC ≠ CE

Find the value of x y and z below !
ehidna [41]

Answer:

x=67, y=121, z=65

Step-by-step explanation:

One property of parallelogram is that opposite angles have the same measure, so we can write down:

(y-9)=112\\y=121

Another property is that two adjacent angles are supplementary (meaning that they add up to 180 degrees). Thus, the following equations are true:

(z+3)+112=180\\(x+1)+112=180

Solve the equations:

(z+3)+112=180\\z+115=180\\z=65\\(x+1)+112=180\\x+113=180\\x=67

To check, add up all 4 angles and check if they sum up to 360 degrees:

x=67, y=121, z=65\\(y-9)+(x+1)+(z+3)+112=360\\(121-9)+(67+1)+(65+3)+112=360\\112+68+68+112=360\\360=360

And please ignore the fact that I cannot insert the degree sign :(

What does the y-coordinate have to be for a point to be on the x-axis?​
vesna_86 [32]

Step-by-step explanation:

If we're talking about something like y coordinate being on the x axis, I'd have to say 0. Because it would be on the y axis no matter the coordinates of it isn't a 0. Ex : (0,0) and (0,9). (0,9) would have the point going upwards on the y axis.

Los nutriólogos recomiendan que una persona debe tomar en promedio 2.5 litros de agua en un día, para que esté bien hidratada. ¿
Goshia [24]

the question in English

Nutritionists recommend that a person should drink an average of 2.5 liters of water in a day, to be well hydrated. How many liters of water should a person drink in a month to comply with a good hydration (Consider a month equal to 30 days) Formulate an algebraic expression to determine the total liters of water that a person should drink a given number of days.

Let

x-------> the number of days

y------> the total liters of water

we know that

y=2.5x  ------> algebraic expression to determine the total liters of water that a person should drink a given number of days

For x=30 days (1 month)

substitute in the formula

y=2.5*30=75\ liters

therefore

<u>the answer is</u>

75\ liters
