What % could i make 2/5 of a hour? like 10% of a hour. like that.

yarga [219]

well, we can say that 1 hour is 100%, what is 2/5 hr off of it in percentage?

$\begin{array}{ccll} hour&\%\\ \cline{1-2} 1 & 100\\ \frac{2}{5}& x \end{array} \implies \cfrac{1}{~~ \frac{2}{5}~~}=\cfrac{100}{x}\implies \cfrac{5}{2}=\cfrac{100}{x} \\\\\\ 5x=200\implies x=\cfrac{200}{5}\implies x=40$

What is the value of x

My name is Ann [436]

X=3

Explanation:

A straight line equals 180°, and they give you the one angle of 56°, so you know 56+ the other equation has to equal 180

56+4x+112=180
168+4x=180

Subtract 168 from both sides

4x=12

Divide 4 from both sides

X=3

You can check by filling it in.

56+4*3+112=

12+56+112=180
