Answer:

Top left : x and y are alternate exterior angles :

Top right: x and y are consecutive interior :

Middle left: x and y are corresponding angles :

Middle right: x and y are consecutive interior:

Bottom left: x and y are consecutive interior:

Step-by-step explanation:

Top left : x and y are alternate exterior angles : opposite outside angles

Top right: x and y are consecutive interior : same side on the inside of the lines

Middle left: x and y are corresponding angles : matching corner

Middle right: x and y are consecutive interior: same side on the inside of the lines

Bottom left: x and y are consecutive interior: same side on the inside of the lines

4/10x - 2x + 8/5 = 4/5

mamaluj [8]

$\large\displaystyle\text{$\begin{gathered}\sf \left(\frac{4}{10}\times x\right)-(2 \times x)+\frac{8}{5}=\frac{4}{5} \end{gathered}$}$

Reduce the fraction 4/10, to its minimum expression, extracting and canceling 2.

$\large\displaystyle\text{$\begin{gathered}\sf \frac{2}{5}x-2x+\frac{8}{5}=\frac{4}{5} \end{gathered}$}$

Combine $\bf{\frac{2}{5}x }$ and -2x to get $\bf{-\frac{8}{5}x}$ .

$\large\displaystyle\text{$\begin{gathered}\sf -\frac{8}{5}x+\frac{8}{5}=\frac{4}{5} \ \end{gathered}$}$

Subtract 8/5 from both sides.

$\large\displaystyle\text{$\begin{gathered}\sf -\frac{8}{5}x=\frac{4}{5}-\frac{8}{5} \ \ \end{gathered}$}$

Since 4/5 and 5/8 have the same denominator, join their numerators to subtract them.

$\large\displaystyle\text{$\begin{gathered}\sf -\frac{8}{5}x=\frac{4-8}{5} \end{gathered}$}$

Subtract 8 from 4 to get -4.

$\large\displaystyle\text{$\begin{gathered}\sf -\frac{8}{5}x=-\frac{4}{5} \end{gathered}$}$

Multiply both sides by $\bf{-\frac{5}{8}}$ , the reciprocal of $\bf{-\frac{5}{8}}$ .

$\large\displaystyle\text{$\begin{gathered}\sf x=-\frac{4}{5}\left(-\frac{5}{8}\right) \end{gathered}$}$

Multiply -4/5 by -5/8 (to do this, multiply the numerator by the numerator and the denominator by the denominator).

$\large\displaystyle\text{$\begin{gathered}\sf x=\frac{-4(-5)}{5\times8} \ \to \ \ Multiply \end{gathered}$}$
$\large\displaystyle\text{$\begin{gathered}\sf x=\frac{20}{40} \end{gathered}$}$

Reduce the fraction 20/40 to its lowest expression by extracting and canceling 20.

$\boxed{\large\displaystyle\text{$\begin{gathered}\sf x=\frac{1}{2} \end{gathered}$}}$

the country's population in 1994 was 76 million in 1998 it was 81 million estimate the population in 2016

Valentin [98]

Between 1994 and 1998 the population increased by 5 miliion, approximately 1 1/4 million a year.

2016 - 1998 = 18 years at 1 1/4 million a year = 22 1/2 million

Estimate therefore is: 81 + 22 1/2 = 103 !/2 million
