Question

suma a trei nr.este1100.Daca din fiecare scadem acelasi nr.obtinem 95,140,235.
care sunt nr.?

Answer 1

Deci, se rezolva astfel :

a+b+c=100

$95+140+235=470 (suma_r_e_s_t_u_r_i_l_o_r)$

$1100-470=630 (suma_c_e_l_o_rtrei_n_u_m_e_r_epe_c_a_r_ele-am_s_c_a_z_u_t)$

$630:3=210(numarul_p_ecare_l_-_a_mscazut_d_i_nfiecare_n_u_m_a_r)$

210+95=305(a)
210+140=350(b)
210+235=445(c)

$R=305,350,445$
