ГДЗ по математике 6 класс Дорофеев Задание 754

\[\boxed{\mathbf{754\ (754)}\mathbf{.}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]

\[a + b + c\]

\[\textbf{а)}\ a = 17;b = - 23;c = - 9:\]

\[17 + ( - 23) + ( - 9) = - 6 + ( - 9) = - 15\]

\[\textbf{б)}\ a = - 33;b = - 18;c = 26:\]

\[- 33 + ( - 18) + 26 = - 51 + 26 = - 25\]

\[\textbf{в)}\ a = 25;b = - 19;c = 50:\]

\[25 + ( - 19) + 50 = 6 + 50 = 56\]

\[\textbf{г)}\ a = - 12;b = - 20;c = - 19:\]

\[- 12 + ( - 20) + ( - 19) = - 32 + ( - 19) = - 51\]
