Question

ите уравнение:
а) - 3,5х =-7,
6) 0,6x = -4,8,
в) -2,5х = 1,25,
х=-7:(-3,5),
X= 70:35,
Х=2;
r) 0,17x=-5,1,
A) -0,13x = -3,9, e) -0,2x = -30,​

Answer 1

Ответ:

$- 0.2x = - 30 \\ x = - 30 \div - 0.2 \\ x = - 300 \div - 2 \\ x = 150$

$0.6x = - 4.8 \\ x = - 4.8 \div 0.6 \\ x = - 48 \div 6 \\ x = - 8$

$- 2.5x = 1.25 \\ x = 1.25 \div - 2.5 \\ x = 12.5 \div -25 \\ x = - 0.5$

$0.17x = - 5.1 \\ x = - 5.1 \div 0.17 \\ x = - 510 \div 17 \\ x = - 30$

$- 0.13x = - 3.9 \\ x = - 3.9 \div - 0.13 \\x = - 390 \div - 13 \\ x = 30$
