Find the value of x that makes ABCD a parallelogram <br><br> help plz

ehidna [41]

The angles of a parallelogram add up to 360°
and the opposite angles are equal
so you make the equation: 150+150+5x+5x=360
you solve for x
10x=60
x=6

if my grade in math is a 51.32% and I get at least a 70% on my test. What percentage will my grade go up too? ( test are worth 4

bazaltina [42]

Keeping in mind that 70% of anything is 70/100 * anything, thus

$\bf \begin{array}{ccll}
\stackrel{percentage}{points}&\stackrel{test}{completed}\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
45&1\\\\
x&\frac{70}{100}
\end{array}\implies \cfrac{45}{x}=\cfrac{1}{\frac{70}{100}}\implies \cfrac{45}{x}=\cfrac{\frac{1}{1}}{\frac{7}{10}}
\\\\\\
\cfrac{45}{x}=\cfrac{1}{1}\cdot \cfrac{10}{7}\implies \cfrac{45}{x}=\cfrac{10}{7}\implies \cfrac{45}{x}=\cfrac{10}{7}\implies \cfrac{45\cdot 7}{10}=x
\\\\\\
\cfrac{63}{2}=x\implies \boxed{31.5=x}$

so, you get that many percentage points, now... add that to 51.32.
