Сколько дней ему понадобится чтобы изготовить 2470 деталей. за 12 дней строители отремонтировали 348 км дороги. Сколько километров дороги ремонтировали в каждый из дней ?

Answer 1

23*х+456=732
23*х=732-456
23*х=276
х=276/23
х=12

х/68+6730=7702
х/68=7702-6730
х/68=972
х=972*68
х=66096

67809-7896+y=462502
y=462502-67809+7896
y=402589

1000000-89*a=956479
89a=1000000-956479
89a=43521
a=43521/89
a=489

x-2208/32=8090
x=8090+2208/32
x=8090+69
x=8159

67*x-10986=21777
67x=21777+10986
67x=32763
x=32763/67
x=489

Задача: 2470/95=26 (дней)

Задача: 348/12=29 (км в день)

Answer 2

Solving Equations:

To solve the given equations, we will follow the standard procedure of isolating the variable on one side of the equation. Let's solve each equation step by step.

1. Equation 1: 23 * X + 456 = 732 * X / 68 + 6730 = 7702 * 67809 - 7896 + U = 462502 * 1000000 - 89 * A = 956479 * X - 2208 / 32 = 8090.67 * X - 10986 = 21777

To solve this equation, we need to simplify each expression and isolate the variable on one side.

- Simplifying the equation: 23X + 456 = 732X / 68 + 6730 = 7702 * 67809 - 7896 + U = 462502 * 1000000 - 89A = 956479X - 2208 / 32 = 8090.67X - 10986 = 21777

- Combining like terms: 23X - 732X / 68 = 7702 * 67809 - 7896 + U = 462502 * 1000000 - 89A = 956479X - 2208 / 32 = 8090.67X - 10986 = 21777

- Simplifying further: (23 - 732 / 68)X = 7702 * 67809 - 7896 + U = 462502 * 1000000 - 89A = 956479X - 2208 / 32 = 8090.67X - 10986 = 21777

- Evaluating the expression: (23 - 10.7647)X = 7702 * 67809 - 7896 + U = 462502 * 1000000 - 89A = 956479X - 2208 / 32 = 8090.67X - 10986 = 21777

- Simplifying further: 12.2353X = 7702 * 67809 - 7896 + U = 462502 * 1000000 - 89A = 956479X - 2208 / 32 = 8090.67X - 10986 = 21777

- Isolating X: X = (7702 * 67809 - 7896 + U) / 12.2353 = (462502 * 1000000 - 89A) / 12.2353 = (956479X - 2208 / 32) / 12.2353 = (8090.67X - 10986) / 12.2353 = 21777 / 12.2353

- Evaluating the expression: X = (7702 * 67809 - 7896 + U) / 12.2353 = (462502 * 1000000 - 89A) / 12.2353 = (956479X - 2208 / 32) / 12.2353 = (8090.67X - 10986) / 12.2353 = 1779.68

Therefore, the value of X is approximately 1779.68.

2. Problem 2: Master Ezhednevno manufactures 95 parts per day. How many days will it take to manufacture 2470 parts?

To find the number of days required to manufacture 2470 parts, we can divide the total number of parts by the number of parts manufactured per day.

- Calculation: 2470 / 95 = 26

Therefore, it will take approximately 26 days for Master Ezhednevno to manufacture 2470 parts.

3. Problem 3: Builders repaired 348 km of road in 12 days. How many kilometers of road were repaired each day?

To find the number of kilometers of road repaired each day, we can divide the total distance repaired by the number of days.

- Calculation: 348 / 12 = 29

Therefore, approximately 29 kilometers of road were repaired each day.

Please note that the solutions provided are approximate due to rounding.
