Question

5,2/0,04= (1,8+х)*2,1=7,14

Answer 1

Ответ:

$1)5,2/0,04=130$

2)

$(1,8+x)*2,1=7,14\\3,78 + 2,1x=7,14\\2,1x=7,14-3,78\\2,1x=3,36\\x=1.6$

Пошаговое объяснение:

Answer 2

(1,8+x)∗2,1=7,14

3,78+2,1x=7,14

2,1x=7,14−3,78

2,1x=3,36

x=1.6

Answer 3

Let's break down the equation step by step:

1. 5,2 / 0,04: Dividing 5,2 by 0,04, we get: 5,2 / 0,04 = 130

2. (1,8 + x) * 2,1 = 7,14: Multiplying (1,8 + x) by 2,1, we get: 2,1 * (1,8 + x) = 7,14

Now we can solve for x. To do that, we'll divide both sides of the equation by 2,1: (2,1 * (1,8 + x)) / 2,1 = 7,14 / 2,1

Simplifying further: 1,8 + x = 3,4

Subtracting 1,8 from both sides: x = 3,4 - 1,8

Calculating: x = 1,6

Therefore, the value of x is 1,6.
