Question

помогите пожалуйста ... надо срочно​

Answer 1

1.

$1) - 2.6 \ 2)5.6 \ 3) - 10.4 \ 4)0$

$5) - 6 \ 6) - 22.2 \ 7)12.9$

2.

$1)9 + x = 5 \ x = 5 - 9 \ x = - 4 \ 9 - 4 = 5 \ 5 = 5$

$2) - 33 - y = - 19 \ y = - 33 - ( - 19) \ y = - 14 \ - 33 - ( - 14) = - 19 \ - 19 = - 19$

3.

$1) - 42 + 75 = 33 - 14 = 19 \ 19 - 26 = - 7 + 56 = 49$

$2)12 - 20 = - 8 + 11 = 3 + 6 = \ 9 - 10 = - 1$

$3) 3frac{5}{12} + 1 frac{1}{3} - 4 frac{3}{8} = \ 3 frac{10}{24} + 1 frac{8}{24} - 4 frac{9}{24} =$

$4 frac{18}{24} - 4 frac{9}{24} = frac{9}{24} = frac{3}{8}$

4.

$- 13.24 +4.9 = - 8.34 + 8.24 = \ - 0.1 - 4.9 = - 5 + b \ - 5 times 3 frac{4}{9} = - 5 times frac{31}{9} =$

$- frac{155}{9} = - 17 frac{2}{9}$
