The answer would be 177.4
Answer:
Brian Peters worked for total of 45 hours.
Step-by-step explanation:
Let the total number of hours worked be 'x'.
Now Given:
Hours spent on other projects = 18 hours.
Also Given:
60% of a week's time working on drawings for a new apartment building.
Hours spent on new apartment building = 
We need to find the total hours worked.
Solution:
Now we can say that;
total number of hours worked is equal to sum of Hours spent on new apartment building and Hours spent on other projects.
framing in equation form we get;

Combining like terms we get;

Now Dividing both side by 0.4 we get;

Hence Brian Peters worked for total of 45 hours.
Alright, so all we have to do here is solve the equation!
5 5/8 + m = 9
m = 9 - 5 5/8
Now is the tricky part - doing the subtraction! Let's change 9 to 8 8/8 (which is still equal to 9).
m = 8 8/8 - 5 5/8
Then we can subtract fairly easily!
m = (8 - 5) + (8/8 - 5/8)
m = 3 3/8 miles
Hope this helps!! :)
Multiply everything in the second parenthesis by x.
-3x^3 + 3x^2 + x
Multiply everything in the second parenthesis by 2.
-6x^2 + 6x + 2
Combine these two equations together.
-3x^3 + 3x^2 + x - 6x^2 + 6x + 2
Combine like terms.
-3x^3 - 3x^2 + 7x + 2
Hope this helps!

x² – 2x + 7 = 4x – 10
x² –2x – 4x + 7 + 10= 0
x² –6x + 17 = 0
