Mario tried to solve an equation step by step. \begin{aligned} \dfrac43&=q+\dfrac13 \dfrac43-\dfrac13&=q+\dfrac13-\ dfrac13&\green{\text{Step } 1} \dfrac23&=q&\blue{\text{Ste p } 2} \end{aligned} 3 4 3 4 − 3 1 3 2 =q+ 3 1 =q+ 3 1 − 3 1 =q Step 1 Step 2 Find Mario's mistake.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

step-by-step explanation:

milk=16 large

soda=280 kids

juice box=82 regular

63 soda +63 regular
