Question

Решите уравнения:

1.4,13-1,7х=4,028.

2.64÷(24y+19,04)=3,2.

3.5,6÷(х+1,6)=0,08.

4.х÷1,15=0,16.

5.0,408÷х=1,7.

6.5,6÷х+0,16=0,3.

Answer 1

$4.13 - 1.7x = 4.028 \ 1.7x = 4.13 - 4.028 \ 1.7x = 0.272 \ x = 0.272 div 1.7 \ x = 2.72 div 17 \ x = 0.16$

$64 div (24y + 19.04 )= 3.2 \ 24y + 19.04 = 64 div 3.2 \ 24y + 19.04 = 640 div 32 \ 24y + 19.04 = 20 \ 24y = 20 - 19.04 \ 24y = 0.96 \ y = 0.96 div 24 \ y = 0.04$

$5.6 div (x + 1.6) = 0.08 \ x + 1.6 = 5.6 div 0.08 \ x + 1.6 = 560 div 8 \ x + 1.6 = 70 \ x = 70 - 1.6 \ x = 68.4$

$x div 1.15 = 0.16 \ x = 0.16 times 1.15 \ x = 0.184$

$0.408 div x = 1.7 \ x = 0.408 div 1.7 \ x = 4.08 div 17 \ x = 0.24$

$5.6 div x + 0.16 = 0.3 \ 5.6 div x = 0.3 - 0.16 \ 5.6 div x = 0.14 \ x = 5.6 div 0.14 \ x = 560 div 14 \ x = 40$
