Marcia can make 5 candles in an hour. kevin can make only 4 candles in an hour, but he already has 7 completed candles. explain to marcia how she can use a system of equations to determine when she will have the same number of candles as kevin. use complete sentences.

idk

step-by-step explanation:

use that smart brain

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
