Suma doua numere este 702.Diferenta lor este un sfert din scazator .Afla cele doua numere dAU COROANA
Molodets [167]

Answer:

Cele două numere căutate sunt:

  1. <u>390 </u>
  2. <u>312</u>

Step-by-step explanation:

Pentru a rezolva necunoscutul cu aceste două numere, trebuie create două ecuații cu două necunoscute X și Y cu informațiile obținute: În primul rând, știm că suma celor două numere este egală cu 702, prin urmare:

1. <u>X + Y = 702 </u>

Apoi se menționează că diferența (adică scăderea) dintre cele două numere este egală cu un sfert din numărul cel mai mic, pentru a avea o referință, vom identifica variabila Y ca fiind cel mai mic număr, deci a doua ecuație ar fi:

2. <u>X - Y = 0,25Y</u> sau <u>Y / 4 </u>

Ștergem variabila X în a doua ecuație:

  • X - Y = 0,25Y
  • X = 0,25Y + Y
  • <u>X = 1,25Y </u>

Ecuația 1 este acum folosită cu X-ul șters:

  • X + Y = 702
  • 1,25Y + Y = 702
  • 2,25Y = 702
  • Y = 702 / 2,25
  • <u>Y = 312 </u>

Acum, din moment ce se știe că este X = 1.25Y, valoarea lui Y este înlocuită și obținem:

  • X = 1,25Y
  • X = 1,25 * 312
  • <u>X = 390</u>

1/6 of the pot is 2/12
1/12 + 2/12 is 3/12
1 - 3/12 is 9/12 = 3/4

10 : EB = 5 : 3
5 EB = 30
EB = 6
With Pythagorean theorem:
CE² = 10² - 6² = 10 - 36 = 64
CE = 8
ED = 5
AB = 2 · 5 = 10
