Kiran is playing a video game. He earns 3 stars for each easy level he completes and 5 stars for each difficult level he completes. He completes more than 20 levels total and earns 80 or more stars. Create a system of inequalities that describes the constraints in this situation. Let $$ represent the number of easy levels that Kiran completes Let $$ represent the number of difficult levels that Kiran completes.

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

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
