Answer 1

Ответ:

3,2

$2.5x + 10x = 40 \\ 12.5x = 40 \\ x = 40 \div 12.5 \\ x = 400 \div 125 \\ x = 3.2$

Answer 2

Ответ:

12,5x=40

x=40:12,5

x=3,2

Answer 3

To solve the equation 2.5x + 10x = 40, we can combine the like terms on the left side of the equation:

2.5x + 10x = 40 (2.5 + 10)x = 40 12.5x = 40

Next, we isolate x by dividing both sides of the equation by 12.5:

12.5x = 40 x = 40/12.5 x ≈ 3.2

Therefore, the solution to the equation is x ≈ 3.2.
