Question

16х-х=3105   х+х+30=928. 807*95=?          350886:86=?           6200*89=?

Answer 1

16х-х=3105

15х=3105

х=207

х+х+30=928

2х+30=928

2х=928-30

2х=898

х=449

807*95=76665

350886:86=408(6 ост)

6200*89=551800

Answer 2

Let's solve the equations step by step:

1. 16x - x = 3105

Combining like terms: 15x = 3105

Dividing both sides by 15: x = 3105/15 x = 207

Therefore, x = 207.

2. x + x + 30 = 928

Combining like terms: 2x + 30 = 928

Subtracting 30 from both sides: 2x = 928 - 30 2x = 898

Dividing both sides by 2: x = 898/2 x = 449

Therefore, x = 449.

Now let's solve the given multiplications:

3. 807 * 95 = ?

To find the product, you multiply 807 by 95:

807 * 95 = 76,665

Therefore, 807 multiplied by 95 equals 76,665.

4. 350,886 : 86 = ?

To find the quotient, you divide 350,886 by 86:

350,886 ÷ 86 = 4,081

Therefore, 350,886 divided by 86 equals 4,081.

5. 6,200 * 89 = ?

To find the product, you multiply 6,200 by 89:

6,200 * 89 = 551,800

Therefore, 6,200 multiplied by 89 equals 551,800.
