Answer 2

Let's solve the equations one by one:

1. 3 ÷ 3 = 10 (2қалд) To find the value of "?," we need to determine what number, when divided by 3, gives a quotient of 10 with a remainder of 2.

We can set up the equation: 3x + 2 = 10, where "x" represents the unknown number we are trying to find.

Subtracting 2 from both sides of the equation, we have: 3x = 8.

Now, dividing both sides by 3, we find: x = 8 ÷ 3 = 2 (2/3).

So, the value of "?" is 2 (2/3).

2. 77 ÷ ? = ? (5қалд) Here, we need to determine what number, when divided into 77, gives the same quotient and leaves a remainder of 5.

Let's assume the unknown number is "x." We can set up the equation: 77 ÷ x = x + 5.

Rearranging the equation, we get: x^2 + 5x - 77 = 0.

To solve this quadratic equation, we can use factoring, completing the square, or the quadratic formula. However, after attempting to factorize the equation, it does not appear to factor nicely.

Using the quadratic formula, we have: x = (-5 ± √(5^2 - 4(-77)))/(2).

Evaluating the expression inside the square root: √(25 + 308) = √(333) ≈ 18.248.

So, applying the quadratic formula: x ≈ (-5 ± 18.248)/(2).

Therefore, we have two possible solutions:

• x ≈ (-5 + 18.248)/2 ≈ 6.624.
• x ≈ (-5 - 18.248)/2 ≈ -11.624.

Since we're looking for a positive number, the value of "?" is approximately 6.624.

3. 4 ? ÷ 7 = ? (5қалд) To find the value of "?," we need to determine what number, when multiplied by 4 and then divided by 7, gives the same quotient and leaves a remainder of 5.

Let's assume the unknown number is "x." We can set up the equation: (4x)/7 = x + 5.

Multiplying both sides by 7 to eliminate the fraction, we have: 4x = 7x + 35.

Subtracting 7x from both sides, we get: -3x = 35.

Dividing both sides by -3, we find: x = 35 / -3 ≈ -11.667.

So, the value of "?" is approximately -11.667.

4. 9 ÷ 2 = ? (1қалд) To find the value of "?," we need to divide 9 by 2 and find the quotient with a remainder of 1.

When we divide 9 by 2, we get a quotient of 4 with a remainder of 1.

Therefore, the value of "?" is 4.

Summary:

1. ? = 2 (2/3)
2. ? ≈ 6.624
3. ? ≈ -11.667
4. ? = 4
