Answer:

Step-by-step explanation:
Hello,
let's find a and b reals so that


we identify the terms in 
9 = 3a
we identify the terms in x
-18 = 3b + a
we identify the constant terms
-7 = b
so ti goes with a = 9/3 = 3, b = -7
so we can write

so 
hope this helps
Nearest 10 is according to the last digit.
if the digit is >5, it +1 to the tenth digit. If it's <5, it will be reduced to 0.
for your case, 392, 2 < 5, therefore rounded up to nearest tenth is 390.
Hello :

110000 is the total dividends of both preferred stock and common stock
So we need to find the dividend per share common stock
First find the total dividends of preferred stock
5,000×2.38=11,900
Subtract the total dividends of preferred stock for the total dividends to find the total dividends of common stock
110,000−11,900=98,100
Finally divide the total dividends of common stock by the number of common stock to find the dividend per share of common stock
98,100÷12,000=8.175....answer
Hope it helps!
