Answer:

x = $2\dfrac{3}{7}$

Explanation:

$\hookrightarrow 35.1 = 12.9 + 10.2x$

$\hookrightarrow 10.2x = 35.1 - 12.9$

$\hookrightarrow \dboxed{10.2x = 22.2}$

$\hookrightarrow x =\dfrac{22.2}{10.2}$ * 5

$\hookrightarrow x = \dfrac{111}{51}$

$\hookrightarrow x = \dfrac{37}{17}$

$\hookrightarrow x = 2\dfrac{3}{7}$

Please check the explanation.

Step-by-step explanation:

Solving the expressions

7)

given the expression

$\left(-7\right)+\:\left(-10\right)\:-\:5\:+2$

$\mathrm{Follow\:the\:PEMDAS\:order\:of\:operations}$

$\mathrm{Add\:and\:subtract\:\left(left\:to\:right\right)}\:\:$

$\mathrm{Apply\:rule\:}+\left(-a\right)\:=\:-a$

so

$=\left(-7\right)-10-5+2$

$=-17-5+2$

$=-22+2$

$=-20$

8)

$\left(-9\right)+4+\left(-8\right)-\left(-7\right)$

$\mathrm{Follow\:the\:PEMDAS\:order\:of\:operations}$

$\mathrm{Add\:and\:subtract\:\left(left\:to\:right\right)}\:\:$

$\mathrm{Apply\:rule\:}+\left(-a\right)\:=\:-a$

so

$=-5+\left(-8\right)-\left(-7\right)$

$=-5-8-\left(-7\right)$

$=-13-\left(-7\right)$

$=-13+7$

$=-6$

9)

$\left(-6\right)\:-\:\left(2\:\times \:4\right)\:-\:\left(-1\right)\:$

$\mathrm{Follow\:the\:PEMDAS\:order\:of\:operations}$

$\mathrm{Add\:and\:subtract\:\left(left\:to\:right\right)}\:\:$

so

$\left(-6\right)-\left(2\times \:4\right)-\left(-1\right)$

Calculate within parentheses

$=\left(-6\right)-8-\left(-1\right)$

$=-14-\left(-1\right)$

$=-14+1$

$=-13$

10)

$\left(-8\right)\:+\:\left(-4\:\div \:-4\right)\:-\:8$

solving

$\left(-8\right)+\left(-\frac{4}{-4}\right)-8$

$\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a$

$=-8-\frac{4}{-4}-8$

$=-8-\left(-1\right)-8$

$\mathrm{Apply\:rule}\:-\left(-a\right)=a$

$=-8+1-8$

$\mathrm{Add/Subtract\:the\:numbers:}\:-8+1-8=-15$

$=-15$
