4. Найди значения выражений 70-b и b+8 b=32, b=34, b=46, b=68.

Нужно найти значение выражений $$70 - b$$ и $$b + 8$$ при заданных значениях $$b$$. 1) $$b = 32$$: - $$70 - b = 70 - 32 = 38$$ - $$b + 8 = 32 + 8 = 40$$ 2) $$b = 34$$: - $$70 - b = 70 - 34 = 36$$ - $$b + 8 = 34 + 8 = 42$$ 3) $$b = 46$$: - $$70 - b = 70 - 46 = 24$$ - $$b + 8 = 46 + 8 = 54$$ 4) $$b = 68$$: - $$70 - b = 70 - 68 = 2$$ - $$b + 8 = 68 + 8 = 76$$ Ответ: * $$b = 32$$: $$70 - b = 38$$, $$b + 8 = 40$$ * $$b = 34$$: $$70 - b = 36$$, $$b + 8 = 42$$ * $$b = 46$$: $$70 - b = 24$$, $$b + 8 = 54$$ * $$b = 68$$: $$70 - b = 2$$, $$b + 8 = 76
