Answer:
I think is 280km :))))))
Andre covered 280km.
Step-by-step explanation:
I would say make a proportion:
?= distance covered
4 - 160
7 - ?
Solve: 7×160÷4=280.
To find the inverse you switch x and y
3y-4x=6
So 3y = 4x+6
and Y = 4/3x + 2
the last one I think
? = 24
Pizzas = 3
Because of this, burgers must be 2
2³ = 8
Tacos = 8
8 + 8 + 8 = 24
