Question

5×с+111=1000-334 180÷d=15+1800÷600​

Answer 1

Ответ:

Пошаговое объяснение:

5с+111=1000-334

5с+111=666

5с=666-111

5с=555

с=111

...............................................

180÷d=15+1800÷600​

180:d=15+3

180:d=18 помножим на d

180=18d

d=10

Answer 2

5×с+111=1000-334

5×с+111=666

5×с=666-111

5×с=555

с=555:5

с=111

5×111+111=1000-334

        666=666

180÷d=15+1800÷600

180÷d=18

d=180:18

d=10

180÷10=15+1800÷600

       18=18

Answer 3

Let's solve these two equations step by step:

1. 5×с + 111 = 1000 - 334

First, we'll simplify the right side of the equation:

1000 - 334 = 666

So now we have:

5×с + 111 = 666

Next, we'll isolate the variable с by moving 111 to the other side of the equation by subtracting it from both sides:

5×с = 666 - 111 5×с = 555

Now, to solve for с, we'll divide both sides by 5:

с = 555 ÷ 5 с = 111

So the value of с is 111.

2. 180 ÷ d = 15 + 1800 ÷ 600

First, we'll simplify the right side of the equation:

15 + 1800 ÷ 600 = 15 + 3

Now, we have:

180 ÷ d = 15 + 3

Combine the numbers on the right side:

180 ÷ d = 18

To solve for d, we'll divide both sides by 180:

d = 180 ÷ 18 d = 10

So the value of d is 10.

To summarize:

• с = 111
• d = 10
