Answer 1

1.х=72-18*3=72-54=18
2.х=470+230+290=990
3.х=630:7:15=90:15=6

1.400800-(27860-580)=400800-27280=373520
2.50786+(24273:9-97)=50786+(2697-97)=50786+2600=53386
3.706-132:6=706-22=684

Answer 2

1. Решение уравнений:

1.72 - x = 18 * 3 + 2

To solve for x, we can start by simplifying the right side of the equation:

1.72 - x = 54 + 2

Next, we can combine like terms:

1.72 - x = 56

To isolate x, we can subtract 1.72 from both sides of the equation:

1.72 - 1.72 - x = 56 - 1.72

x = 54.28

So the solution to the first equation is x = 54.28.

х - 290 = 470 + 230

To solve for x, we can start by simplifying the right side of the equation:

x - 290 = 700

Next, we can isolate x by adding 290 to both sides of the equation:

x - 290 + 290 = 700 + 290

x = 990

So the solution to the second equation is x = 990.

3.15 * x = 630:7

To solve for x, we can start by simplifying the right side of the equation:

3.15 * x = 90

Next, we can isolate x by dividing both sides of the equation by 3.15:

(3.15 * x) / 3.15 = 90 / 3.15

x = 28.57

So the solution to the third equation is x = 28.57.

2. Решение уравнений:

1. 400.800 - (3.980 * 7 - 580) + 2 + 50786 + (8091 * 3:9 - 97) + 3 + 706 - 13200:100:6

To solve this equation, we need to follow the order of operations, which is often remembered as PEMDAS (parentheses, exponents, multiplication and division from left to right, and addition and subtraction from left to right).

First, let's simplify the expression inside the parentheses:

3.980 * 7 - 580 = 27.86

Next, let's simplify the expression inside the second parentheses:

8091 * 3:9 - 97 = 2703 - 97 = 2606

Now, let's simplify the expression involving division:

13200:100:6 = 220:6 = 36.67

Now, let's substitute the simplified expressions back into the original equation:

400.800 - (27.86 - 580) + 2 + 50786 + (2606) + 3 + 706 - 36.67

Next, let's simplify the addition and subtraction from left to right:

400.800 - (27.86 - 580) + 2 + 50786 + 2606 + 3 + 706 - 36.67

= 400.800 - (-552.14) + 2 + 50786 + 2606 + 3 + 706 - 36.67

= 400.800 + 552.14 + 2 + 50786 + 2606 + 3 + 706 - 36.67

= 52316.27

So the solution to the second equation is 52316.27.

3. Решение уравнений:

23 + м + 06 + см = ...см + 62335 кг = ...т + ...кг 2 ч 45 мин = ... мин 584 мм = ... см + ... мм

Let's simplify each equation step by step:

23 + м + 06 + см = ...см Here, we have the sum of 23, м (which represents an unknown value), 06, and см (centimeters). To solve for the unknown value м, we need more information or clarification about the equation.

...см + 62335 кг = ...т + ...кг Here, we have the sum of ...см (unknown centimeters) and 62335 кг (kilograms). We also have the sum of ...т (unknown tons) and ...кг (unknown kilograms). To solve for the unknown values, we need more information or clarification about the equation.

2 ч 45 мин = ... мин Here, we have 2 hours and 45 minutes. To convert this to minutes, we can multiply the number of hours (2) by 60 and then add the number of minutes (45):

2 * 60 + 45 = 120 + 45 = 165 minutes

So the solution to this equation is 165 minutes.

584 мм = ... см + ... мм Here, we have 584 millimeters. To convert this to centimeters, we can divide the number of millimeters (584) by 10:

584 / 10 = 58.4 centimeters

So the solution to this equation is 58.4 centimeters.

Please provide more information or clarification for the first two equations to solve for the unknown values.
