Irina,Teodor și Andrei au participat la un concurs.Irina și Teodor au obținut împreună 559 de puncte,Teodor și Andrei au împreun
andreev551 [17]

Answer:

Numărul de puncte:

Irina a obținut = x = 245 puncte

Teodor a obținut = y = 314 puncte

Andrei a obținut = z = 286 puncte

Step-by-step explanation:

Să ne reprezentăm

Numărul de puncte:

Irina a primit = x

Teodor got = y

Andrei got = Z

Irina, Teodor și Andrei au participat la un concurs.

Irina și Teodor au obținut 559 de puncte împreună

x + y = 559 ....... Ecuația 1

Teodor și Andrei au obținut 600 de puncte împreună

y + z = 600 ...... Ecuația 2

y = 600 - z

Irina și Andrei 531 puncte.

x + z = 531 ....... Ecuația 3

Substitui

600- z pentru y în ecuația 1

x + 600 - z = 559

Colectează ca termeni

x - z = 559 - 600

x - z = -41 ..... Ecuația 4

Combinând ecuația 3 și 4 împreună

x + z = 531 ....... Ecuația 3

x - z = -41 ..... Ecuația 4

Am face și ecuația 3 și 4 împreună pentru a elimina z

2x = 490

x = 490/2

x = 245 puncte

Rezolvarea pentru z folosind ecuația 4

x - z = -41 ..... Ecuația 4

245 - z = -41

Colectează ca termeni

z = 245 + 41

z = 286 puncte

Rezolvarea pentru y

y = 600 - z

y = 600 - 286

y = 314 puncte

Prin urmare,

Numărul de puncte:

Irina a obținut = x = 245 puncte

Teodor a obținut = y = 314 puncte

Andrei a obținut = z = 286 puncte

Nadusha1986 [10]

Answer:

8.5 feet

Step-by-step explanation:

To find the volume of a rectangular prism, you must multiply the area of the base by the height. Conversely, if you wanted to find the height of the prism, you could simply divide the volume by the area of the base. 1360/160=8.5 feet. Hope this helps!
