Question

(15-x:60)умножать на 30 равно 270

Answer 1

1) при раскрытии скобок слева получится 450-x/2=270
2)переносим 450 с отрицательным знаком вправо, отнимаем от 270 450 = -180
3)остаётся -x/2=-180, минусы убираем
4) x/2=180
5)x=2*180
6)x=360

Answer 2

(15 - Х : 60) х 30 = 270
15 - Х : 60 = 270 : 30
15 - Х : 60 = 9
-Х : 60 = - 15 +9
-Х : 60 = -6
Х =6 х 60
Х =360
проверка: ( 15 - 360 : 60) х 30 = 270
                                        270 = 270

Answer 3

To solve the equation (15 - x) * 30 = 270, we can follow these steps:

1. Distribute the 30 to both terms inside the parentheses: 30 * 15 - 30 * x = 270

2. Simplify the equation: 450 - 30x = 270

3. Move the constant term to the other side of the equation by subtracting 450 from both sides: -30x = 270 - 450 -30x = -180

4. Divide both sides of the equation by -30 to solve for x: x = (-180) / (-30) x = 6

Therefore, the value of x that satisfies the equation (15 - x) * 30 = 270 is x = 6.
