Y=40/7x-7/4 Answer
eliminate everything from the Y.
It’s the last one: 2x+1=-x+7
Alees and Emma spend 1064 hours together
<em><u>Solution:</u></em>
Given that, Alees and Emma design an office park in 28 weeks
Each architect spends 19 hours each week on this project
To find: Total number of hours the architects work on this project
From given,
Total number of weeks = 28
Each architect spends 19 hours each week
Therefore,
Time spent in one week by Alees = 19 hours
Time spent in one week by Emma = 19 hours
<em><u>Total number of hours the architects work on this project</u></em>

Thus, they spend 1064 hours together
You can do part a using The Pythagoras theorem:-
30^2 = x^2 + 24^2
x^2 = 30^2 - 14^2 = (30+24)(30-24) = 324
x = 18
1,300
4 is less than five so you round it down
