Question

Решительно уравнения: 0.4x=36.4; 7.02/(y+1.2)=1.8

Answer 1

Вот держи это мая сестра нашла в тетрадке 8/8 x + 1/8 x = 9/8

Answer 2

1. 0.4x = 36.4

To solve for x, we can start by dividing both sides of the equation by 0.4:

0.4x/0.4 = 36.4/0.4

Simplifying:

x = 91

Therefore, the solution is x = 91.

2. 7.02/(y+1.2) = 1.8

To solve for y, we can start by multiplying both sides of the equation by (y+1.2):

7.02 = 1.8(y+1.2)

Simplifying:

7.02 = 1.8y + 2.16

Subtracting 2.16 from both sides:

4.86 = 1.8y

Dividing both sides by 1.8:

y = 2.7

Therefore, the solution is y = 2.7.
