\[\begin{array}{|c|c|c|c|c|c|c|c|} \hline \text{Слагаемое} & 9 & \textcolor{#e03131}{\mathbf{8}} & 3 & \textcolor{#e03131}{\mathbf{0}} & 0 & 15 & \textcolor{#e03131}{\mathbf{20}} \\ \hline \text{Слагаемое} & \textcolor{#e03131}{\mathbf{8}} & 50 & \textcolor{#e03131}{\mathbf{9}} & 16 & \textcolor{#e03131}{\mathbf{20}} & 30 & 9 \\ \hline \text{Сумма} & 17 & 58 & 12 & 16 & 20 & \textcolor{#e03131}{\mathbf{45}} & 29 \\ \hline \end{array}\]
\[\begin{aligned} 47 + 6 &= \textcolor{#e03131}{\mathbf{53}} & \qquad 50 + 12 &= \textcolor{#e03131}{\mathbf{62}} & \qquad 38 - 4 &= \textcolor{#e03131}{\mathbf{34}} \\ 32 - 4 &= \textcolor{#e03131}{\mathbf{28}} & \qquad 70 - 9 &= \textcolor{#e03131}{\mathbf{61}} & \qquad 68 - 4 &= \textcolor{#e03131}{\mathbf{64}} \end{aligned}\]
Сделай схематический чертёж и реши задачу.
\(1)\ 3 + 4 = \textcolor{#e03131}{\mathbf{7}}\text{ (м.)}\)
\(2)\ 3 + 7 = \textcolor{#e03131}{\mathbf{10}}\text{ (м.)}\)
Ответ: \(\textcolor{#e03131}{\mathbf{10}}\) машин.
\[\begin{aligned} \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{7}}\kern0.035em} + \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{7}}\kern0.035em} + \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{7}}\kern0.035em} + \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{7}}\kern0.035em} &= 7 \cdot 4 \\ 6 \cdot \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{3}}\kern0.035em} &= 6 + 6 + 6 \\ \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{3}}\kern0.035em} \cdot \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{5}}\kern0.035em} &= 3 + 3 + 3 + 3 + 3 \\ \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{3}}\kern0.035em}\hspace{-0.04em}\boxed{\kern0.035em\textcolor{#e03131}{\mathbf{4}}\kern0.035em} + \boxed{\kern0.035em\textcolor{#e03131}{\mathbf{3}}\kern0.035em}\hspace{-0.04em}\boxed{\kern0.035em\textcolor{#e03131}{\mathbf{4}}\kern0.035em} &= 34 \cdot 2 \end{aligned}\]
