Sam worked a total of 36 hours. over two weeks he worked twice as many hours in the second week as the first. how many hours did he work in the first week.?

x+2x=36

3x=36

(divide by 3) x=12

Therefore he worked 12 hours in the first week and 24 in the second, totalling 36 hours altogether :)

yes

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
