Mira has breakfast at a restaurant. She leaves a 20% tip of $1.80.

lutik1710 [3]

let's say the breakfast price was "x", so that's the 100%, and we know she gave 20% of that and that is 1.80.

so, 1.80 is 20%, and "x" is the 100%, what is "x"?

$\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 1.80&20\\ x&100 \end{array}\implies \cfrac{1.80}{x}=\cfrac{20}{100}\implies \cfrac{1.8}{x}=\cfrac{1}{5} \\\\\\ 9.0=x\implies 9=x$

a trapezoid has one base of 10 inches,an altitude of 6 inches and an area of 51 square inches, find the length of the other base

Inessa [10]

$\bf \textit{area of a trapezoid}\\\\ A=\cfrac{h(a+b)}{2}~~ \begin{cases} a,b=\stackrel{bases}{parallel~sides}\\ h=height\\ ---------\\ a=10\\ h=6\\ A=51 \end{cases}\implies 51=\cfrac{6(10+b)}{2} \\\\\\ 51=3(10+b)\implies \cfrac{51}{3}=10+b\implies 17=10+b\implies 7=b$
