Ann is 24 and two times as old as Mary was , when Ann was as old as mary is now. wie löse ich diese gleichung?

Vom Fragesteller als hilfreich ausgezeichnet

-->ann ist 24 und war doppelt so alt wie mary, als sie(ann) so alt wie mary (jetzt) war.
Ann = 24 Jahre
Mary = x Jahre
als Ann so alt war, wie Mary jetz is (vor y Jahren):
Ann = x
Mary = x-y
=> x+y = 24
und wir wissen weiter, dass Ann jetz doppelt so alt ist, wie Mary damals
=> 24 = 2(x-y)

Damit haben wir zwei Gleichungen mit zwei Unbekannten, das sollten wir also lösen können.
x = 24-y
24 = 2(24-y-y) = 2*(24-2y) = 48 - 4y => 24 = 4y => y = 6
=> x = 18

Also is Mary jetz gerade 18 Jahre.
Probe: Mary is 6 Jahre jünger als Ann, als Ann 18 war, war Mary 12 und 12*2=24.

Geht das vlt auch ein bisschen einfacher ? ich meine das man es verstht wäre nett danke troztden


Einfach ein bisschen nachdenken.

Mary ist jetzt 18. Als Mary 12 war, war Ann 18.

It as preparatory object?

Im Internet steht diese Erklärung: It is used as a preparatory object when the object of a verb is an infinitive expression or a clause with an adjective or noun complement. --> das verstehe ich nicht!

Zum Beispiel: I find it difficult to talk to her. --> I find to talk to her difficult.

Wo ist hier überhaupt das object des verbes?

Kann jemand diese Thematik erklären?

Hallo ich habe im März meine Englisch-Prüfung, da muss ich etwas über meine Familie erzählen und wollte wissen ob der Text so passt?

Ladies and Gentelmen,

today I would like to welcome you all to my presentation. In my presentation, I will introduce my family to you. My name is Lisa Maier. I am 14 years old and I live in Ersbach. Ersbach is a small town in the south of Germany.

Originally I came from Gräfenhainichen, a city in the east of Germany. Because of work, my family moved here in 2005. At this time I was 2 years old.

At first we lived in Reichenbach, a small village near Ersbach. In this house my grandmother died last year. So we decided to move to Ersbach. Now I live together with my mother and grandfather in a semi-detached house.

Aside from the fact that my grandmother died I would like to tell you something about her. Her name was Karin and she was 72 years old. She was born in 1943 in Jüdenberg.

So we come to my grandfather. His name is Bruno. He is 76 years old and pensioner. He was born in Kasale in 1941. Today Kasale is located in Poland.

My mother's name is Annett. She is 46 years old and works as an Nursing assistant at the Kloster Sießen near Bad Saulgau. She grew up in the former GDR and originally she learned the job of the gardener. When we moved here, she decided to go back to school.

I also have 2 siblings. A big sister, her name is Carolin. She is 28 years old, housewife and married. She already has a little son. His name is Lisandro and he is 4 years old. Her husband is called Roman, 31 years old and a carpenter.

And a big brother. His name is Tim. He is 23 years old and lives in Fronreute. He is a machining mechanic. Few years ago he went to the secondary school in Bad Schussenried.

Finally, I would like to introduce you to our cat. She is called Putzi and is 4 years old.

As soon as I have my secondary school leaving certificate, I would like to make the next higher school-leaving qualification. With this graduation I will be able to start my training as a nurse.

Thank you for listening.

There are times

When life calls out for a change,

A transition

Like the seasons.

Our spring was wonderful,

But summer's over now.

And we missed out in autumn.

And now all of a sudden,it's cold.

It's so cold,everything-

Everything is freezing over.

Our love fell asleep.

And the snow took it by surprise.

But if you fall asleep in the snow,

You don't feel death coming.
