6.

$d)0.5 \times 1.7 \times 20 + 3 \frac{1}{3} \div {( - \frac{1}{3} )}^{2} = 30 \frac{1}{8} = 30.125$

7.

$s = 10x$

8.

$1.5 (x - 2) -2(3 - 1.5x) = 1.5( - 0.2 - 2) - 2(3 - 1.5 \times ( - 1.5) = 1.5 \times 2.2 - 2(3 + 0.3) = - 3.3$

9.

$2x - (3x - 4(x - 2) + 1) = 2x - ( - x + 9) = 2x + x - 9 = 3x - 9$

10 не очень поняла.
