Abag contains 10 paise, 25 paise and 50 paise coins. the number of 25 paise coins is three times the number of 10 paise coins. if 50 paise coins are 5 more than 25 paise coins and the total value of the money in the bag is rs 120, find the number of 10 paise coins.

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

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
