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
