Answer:

The quotient is 2x^2 - x + 1.

Step-by-step explanation:

If x + 1 is the divisor in long division, then -1 is the divisor in synthetic division:

-1 / 2 1 0 1

-2 1 -1

----------------------

2 -1 1 0

The quotient is 2x^2 - x + 1. The coefficients were obtained through synthetic division.

How many adult tickets were sold if each adult ticket sold was $6 and each student ticket was $4.50 and 260 tickets were sold fo

erik [133]

Answer:

Adult tickets sold: 156

Step-by-step explanation:

Adult ticket: x

Student ticket: y

x + y = 260 ===> -6(x + y = 260) ===> -6x -6y = -1560

6x + 4.5y = 1404 ===> 6x + 4.5y = 1404

________________

add the two equations to eliminate a variable: -1.5y = -156

divide by -1.5: y = 104

substitution to find x:

x + y = 260

x + 104 = 260

x = 156

How many days will it take for a sum of $4,000 to earn $80 interest if it is deposited in a bank paying ordinary simple interest

Maksim231197 [3]

Answer:

It will take 146 days to earn an interest of $80.

Step-by-step explanation:

The simple interest formula is:

$I=\frac{P\times r\times t}{100}$

It is provided that:

I = $80

P = $4,000

r = 5% p.a.

Compute the time required as follows:

$I=\frac{P\times r\times t}{100}$

$t=\frac{I\times 100}{P\times r}$

$=\frac{80\times 100}{4000\times 5}\\\\=0.4\ \years\\\\=0.4\times 365\ days\\\\=146\ days$

Thus, it will take 146 days to earn an interest of $80.
