Answer:
Dan eat [tex]2\frac{2}{3}[/tex] pizzas
Step-by-step explanation:
Let
x-----> amount of pizza Jay ate
y-----> amount of pizza Dan ate
we know that
[tex]x=\frac{2}{3}[/tex] ----> equation A
[tex]y=4x[/tex] -----> equation B
substitute equation A in the equation B and solve for y
[tex]y=4(\frac{2}{3})=\frac{8}{3}[/tex]
Convert to mixed number
[tex]\frac{8}{3}=\frac{6}{3}+\frac{2}{3}=2\frac{2}{3}[/tex]
