Rezolvati problema prin metoda figurativa:
Anna35 [415]

Ne este dat numărul total de elevi = 30.

Să presupunem că numărul de băieți este egal cu numărul de fete.

Dacă împărțim 30 cu 2, obținem 15.

Deci, numărul de băieți = 15 și numărul de fete = 15 dacă ambele sunt egale.

"Dar numărul de fete este mai mult de 2 băieți."

Astfel putem scădea 1 din 15 și adăugăm 1 din 15.

După adăugarea a 1 din 15, ajungem

15 + 1 = 16.

Și scăzând de la 1 la 15, ajungem acolo

15-1 = 14.

Deci, numărul de băieți este de 14 și numărul de fete este de 16

Explanation needed
vagabundo [1.1K]

Answer:

A‘‘ (1,6)

Step-by-step explanation:

after a reflection about a horizontal line the x coordinates remain the same

the middle point of the segment AA’ lies on the line so it has y = -1

so we have

(y+y’)/2 = -1

y’ = -2 -y

y‘ = -2 -2 = -4

so A‘ (1,-4)

we can use the same reasoning to find the reflection about y = 1

x‘ = x

(y + y’)/2 = 1

y‘ = 2+4

y’ = 6

A‘‘(1,6)
