Question

У•125-70=1820:4 22580:х+141=23100:30​

Answer 1

Ответ:1) у*125-70=455

у*125=455-70

у*125=385

у=385:125

у=77/25 и получается дробь 3 целых 2/25 (либо 3,08)

2) 225:х+141=770

225:х=770-141

225:х=629

х=0,37

Пошаговое объяснение:

Answer 2

Let's solve each equation step by step:

1. У•125 - 70 = 1820 ÷ 4

First, perform the multiplication and division on the right side:

У•125 - 70 = 455

Now, add 70 to both sides of the equation to isolate У:

У•125 = 455 + 70 У•125 = 525

Finally, divide both sides by 125 to solve for У:

У = 525 ÷ 125 У = 4.2

So, У is equal to 4.2.

2. 22580 ÷ х + 141 = 23100 ÷ 30

First, perform the division on both sides of the equation:

22580 ÷ х + 141 = 770

Now, subtract 141 from both sides to isolate the division:

22580 ÷ х = 770 - 141 22580 ÷ х = 629

Finally, divide both sides by 22580 to solve for х:

х = 22580 ÷ 629 х ≈ 35.83 (rounded to two decimal places)

So, х is approximately equal to 35.83.
