Question

Помгите упростить ввражение 3), 4)

Answer 1

1)(0,09+0,16)x/0,25 -200x*1/8-8*1/8=0,25x/0,25-25x+1=x-25x+1=-24x+1
2)y(0,125-0,1)/0,25 -9y-0,1=0,025y/0,25-9y-0,1=0,1y-9y-1=-8,9y-1

Answer 2

$3) \frac{0.3^2+0.4^2}{0.5^2} *x-(200x+8)* \frac{1}{2 ^{3} } = \\ \\ = \frac{0.09+0.16}{0.25} x-(200x+8)* \frac{1}{8} = \frac{0.25}{0.25} x- \frac{200x}{8} + \frac{8}{8} = \\ \\ =x-25x+1=-24x+1=1-24x$


$4) \frac{y*(0.5^3-0.1)}{0.5^2} -(9y+0.1)= \frac{y*0.025}{0.25} -9y-0.1= \\ =0.1y-9y-0.1=-8.9y-0.1$
