1)720т16кг - 718т80кг : 176 =? 2)3м4см • 402 - 35м35см : 707 =? 3)48:8+32-54:x+7•8=88

Answer 1

Ответ:

Пошаговое объяснение:

1)720 т 16 кг - 718 т 80 кг : 176 =715 т 936 кг

а)718080 кг:176=4080 кг

б)720016 кг-4080 кг=715936 кг =715 т 936 кг

2)3 м 4 см • 402 - 35 м 35 см : 707 =

а)304 см*402=122208 см

б)3535 см : 707=5 см

в)122208 см-5 см=122203 см=1222 м 3 см

3)48:8+32-54:x+7•8=88

а)48:8=6

б)7*8=56

в)94-54:х=88

  54:х=94-88

   54:х=6

    х=54:6

     х=9

Answer 2

1. To solve the first equation, we can simplify the expression on the left side first: 720т16кг - 718т80кг = 1360кг Then we can divide 1360кг by 176 to get the final answer: 1360кг ÷ 176 = 7кг 232г

Therefore, 720т16кг - 718т80кг : 176 = 7кг 232г

2. We can start by converting the length measurements to centimeters: 3м4см = 304см 35м35см = 3535см Then we can simplify the expression on the right side first: 35м35см ÷ 707 = 50см Now we can substitute the values and simplify further: 3м4см • 402 - 50см = 121608см - 50см = 121558см

Therefore, 3м4см • 402 - 35м35см : 707 = 121558см

3. To solve this equation, we can follow the order of operations (PEMDAS) and simplify each part of the equation one by one:

48 : 8 = 6 32 - 54 = -22 7 • 8 = 56 Now we can substitute the values and simplify further: 6 + (-22) + 56 ÷ x + 7 • 8 = 88 Simplify the multiplication and division first: 6 + (-22) + 7 + 56 ÷ x = 88 Simplify further by combining like terms: -9 + 56 ÷ x = 82 56 ÷ x = 91 x = 56 ÷ 91

Therefore, the solution to the equation 48:8+32-54:x+7•8=88 is x = 0.615.
