Mr. Martin's math test, which is worth 100 points, has 29 problems. Each problem is worth either 5 points or 2
points.
Let x be the number of questions worth 5 points and let y
be the number of questions worth 2 points.
x + y = 29, 5x + 2y = 100

need points to ask question

step-by-step explanation:

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
