Question

(a+2)x5=555,368:(25+a)=8
Plz ajutor!!

Answer 1

(a+2)×5=555

a+2=555:5

a+2=111

a=111-2

a=109

368:(25+a)=8

25+a=368:8

25+a=46

a=46-25

a=21

Answer 2

Răspuns:

Explicație pas cu pas:

(a + 2 ) × 5 = 555

a + 2 = 555 : 5

a + 2 = 111

a = 111 - 2

a = 109

Verific:  ( 109 + 2 ) × 5 = 111 × 5 = 555

_____________________________

368 : ( 25 + a ) = 8

25 + a = 368 : 8

25 + a = 46

a = 46 - 25

a = 21

Verific:   368 : ( 25 + 21 ) = 368 : 46 = 8
