Question

помогите решить пожалуйста​

Answer 1

$1)1.5 times (37.13 - 24.34) = 19.185\ 1)37.13 - 24.34 = 12.79 \ 2)1.5 times 12.79 = 19.185$

$2)5 frac{2}{9} div frac{47}{3} + frac{4}{9} = frac{7}{9} \ 1) frac{47}{9} times frac{3}{47} = frac{1}{3}$

$3)3 times (0.2x + 3.2) = 12 \ 0.2x + 3.2 = 12 div 3 = 4 \ 0.2x = 4 - 3.2 = 0.8 \ x = 0.8 div 0.2 = 4$

$6)2m + 4 {m}^{3} - {m}^{2} - 4 {m}^{2} + {m}^{3} \ - 5 {m}^{3} + 5 {m}^{2} = 2m$

$2) frac{1}{3} + frac{4}{9} = frac{3}{9} + frac{4}{9} = frac{7}{9}$

Answer 2

1) 1,5*12,79=19,185

2) 47/9*3/47+4/9=1/3+4/9=7/9

3) 360/8=45

5) угол ACB=57, угол ABC=66, т.к углы ACB и BAC равны

6) 2m+4m³-m²-4m²+m³-5m³+5m²=2m=-17,2*2=-24,4

7) y=A*x+4

6= -2A+4

-2A=2

A=-1
