Harry worked 7 hours last week this is one third as many hours as aiden work how many hours did aiden work

H = number of hours Harry worked
A = number of hours Aiden worked

Harry worked 7 hours last week so we know H = 7
This is one third as many hours as Aiden's time working so H = (1/3)*A
We can multiply both sides by 3 to get 3H = A or A = 3H

If H = 7, then...
A = 3*H
A = 3*7
A = 21

Aiden worked 21 hours

Your answer would be ahere is how: perimeter is how long all the sides are. in a rectangle, there are two sets of parallel sides. so, to find this, we would to the following.(15x2)+(4x2)30+838if you have questions ask! and mark me brainliest! i really wanna level up : 3
