Question

Решите уравнения. a)x:12*5=40 б)x*5=12*40 в)x+40=12*5

Answer 1

Б)х*5=12*40
480=480
480:5=96
а)х:12*5=40
х:60=40
40*60=2400
в)х+40=12*5
60=60
60-40=20

Answer 2

a) x: 12 * 5 = 40

To solve this equation, we need to isolate the variable x. We can do that by multiplying both sides of the equation by 12:

x = 40 * 12

x = 480

Therefore, the solution to the equation is x = 480.

b) x * 5 = 12 * 40

To solve this equation, we can divide both sides by 5:

x = (12 * 40) / 5

x = 480 / 5

x = 96

Therefore, the solution to the equation is x = 96.

c) x + 40 = 12 * 5

To solve this equation, we can subtract 40 from both sides:

x = 12 * 5 - 40

x = 60 - 40

x = 20

Therefore, the solution to the equation is x = 20.
