The bolded numbers are the ones that were given in the question. I got the other figures by subtracting as necessary (wherever I could find 2 already filled in figures).
Answer:
P = $900
Step-by-step explanation:
Simple Interest Formula: 
Where A is the final amount,
P = Principal
r = Interest Rate in Percent or
per annum
t = time in years
From the information given in the question,
A = $918
r = 2% per annum or 
t = 1 year
Lets substitute these values to find P, the principal.

Therefore, P = $900
Answer:
b = -9
Step-by-step explanation:
The function is given as :

The axis of symmetry for this function is x = 3/2
It is required to find the value of b. The axis of symmetry of a parabola is a vertical line that intercepts its vertex at its horizontal coordinate. It can be given by :

Putting x = 3/2 and a = 3 we get :

So, the value of b is -9.
Answer:
x = - 71
Step-by-step explanation:
-11x -44 + 10 x =27
-x = 71
x = - 71
3x - 6 = 7x + 18
(Move terms)
3x - 7x = 18 + 6
(Collect the terms)
(Calculate the sum)
-4x = 24
(Divide both sides by -4)
x = -6
