Answer 1

Ответ:

есть калькулятор вообще то там попробуй окей??!!

Answer 2

Пошаговое объяснение:

(29+15)•46=29•46+15•46=1334+690=2024

73•(24+68)=73•24+73•68=1752+4964=6716

(80-25)•14=80•14-25•14=1120-350=770

15•(121-42)= 15•121-15•42=1815-630=1185

(243-96)•7=243•7-96•7=1701-672=1029

Answer 3

Let's solve each of these equations step by step:

1. (29+15)•46 = 29•? + 15•?

   First, calculate the left side: (29+15)•46 = 44•46 = 2024

   Now, set up the equation: 29•? + 15•? = 2024

   We can factor out '?' on the left side: ?(29 + 15) = 2024

   Combine the numbers in the parentheses on the left side: ?(44) = 2024

   Divide both sides by 44 to solve for '?': ? = 2024 / 44 ? = 46

2. 73•(?+?) = ?•24 + ?•68

   Let's call the unknown value '?' again.

   Set up the equation: 73•( ? + ? ) = ?•24 + ?•68

   Simplify the left side: 73•(2?) = ?•24 + ?•68

   Now, we need to isolate '?'. Let's start by simplifying the right side: 146? = 24? + 68?

   Now, subtract 24? from both sides: 122? = 68?

   Finally, divide both sides by 122 to solve for '?': ? = 68 / 122 ? = 34 / 61

3. (80-25)•? = 80•14 - 25•14

   Calculate the left side: (80 - 25)•? = 55•?

   Calculate the right side: 80•14 - 25•14 = 1120 - 350 = 770

   Now, set up the equation: 55•? = 770

   Divide both sides by 55 to solve for '?': ? = 770 / 55 ? = 14

4. 15•(121-42) = 5•? - 5•?

   Calculate the left side: 15•(121 - 42) = 15•79 = 1185

   Calculate the right side: 5•? - 5•? = 0

   Now, set up the equation: 1185 = 0

   This equation is not valid, as 1185 cannot equal 0.

5. (243-96)•? = 243•7 - ?•7

   Calculate the left side: (243 - 96)•? = 147•?

   Calculate the right side: 243•7 - ?•7 = 1701 - 7?

   Now, set up the equation: 147•? = 1701 - 7?

   Add 7? to both sides: 147? + 7? = 1701

   Combine like terms: 154? = 1701

   Divide both sides by 154 to solve for '?': ? = 1701 / 154 ? ≈ 11.05

So, the solutions are:

1. ? = 46
2. ? ≈ 34/61
3. ? = 14
4. No solution
5. ? ≈ 11.05
