Question

14) (x + 2,6):0,8 = 7,45;1) 3 = x + 2,9x = 36,6;​

Answer 1

Ответ:

x+2,6=7,45×0,8

x+2,6=5,96

x=5,96-2,6

x=3,36

(3,36+2,6)÷0,8=7,45

5,96÷0,8=7,45

7,45=7,45

Answer 2

It seems like you have a couple of equations, but they are not entirely clear due to the formatting. Let's break down and solve each equation step by step:

1. (x + 2.6) / 0.8 = 7.45

To solve for x in this equation, first, isolate x:

(x + 2.6) / 0.8 = 7.45

Multiply both sides by 0.8 to get rid of the denominator:

x + 2.6 = 7.45 * 0.8

x + 2.6 = 5.96

Now, subtract 2.6 from both sides to isolate x:

x = 5.96 - 2.6

x = 3.36

So, the solution for this equation is x = 3.36.

2. 3 = x + 2.9x = 36.6

It appears there might be a formatting issue with this equation. I'm not sure if you meant to write two separate equations or if you intended to continue the equation. Please provide additional information or clarify, and I'll be happy to help you further.
