Acompany ordered 10 boxed lunches from a deli for $74.50. each boxed lunch cost the same amount. which equation represents the proportional relationship between y, the total cost of the boxed lunches, and x, the number of boxed lunches? a) 7.45x = y b) 7.45/x = 10/y c)74.50x = y d. 74.50/x = 10/y

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
