// Function to perform division (x / y) of two numbers x and y. // without using division operator in the code. int divide(int x, int y)
{ // handle divisibility by 0. if (y == 0)

int sign = 1; if (x * y < 0)
Answer: $3.30
Explanation:
You set up a proportion where
9.25 X
------ = -----
2.8 1
Then you cross multiply and see that...
2.8X = 9.25
Then X = 9.25 / 2.8 = 3.30
20 shares at 10 1/2 (or 10.5) = 20 * 10.5 = 210
20 shares at 11 1/4 (or 11.25) = 20 * 11.25 = 225
so the profit made would be : 225 - 210 = $ 15 <==
( - 1, - 8 )
since both equations give y in terms of x we can equate them
3x - 5 = 2x - 6
subtract 2x from both sides of the equation
3x - 2x - 5 = - 6
x - 5 = - 6
add 5 to both sides
x = - 6 + 5 = - 1
substitute x = - 1 into either of the 2 equations for y
y = (3 × - 1) - 5 = - 3 - 5 = - 8
solution to the system is (- 1, - 8 )
Answer:
Step-by-step explanation:
First we will multiply everything by 10 to get rid of the decimals.
Subtract 56 from both sides:
Add 83x to both sides:
Divide both sides by 125:
