New balance=previous balance+finance charge+New transaction

First we need to calculate the finance charge in order to find the new balance

Finance charge=2,103.24×(0.144÷12 months)
=25.24

New balance
2,103.24+25.24+280
=2,408.48

Combine and simplify the following radical expression.

guajiro [1.7K]

Answer:

Step-by-step explanation:

$2 \sqrt{20} + 8 \sqrt{45} - \sqrt{80}$

$= 2 \sqrt{2 \times 2 \times 5} + 8 \sqrt{3 \times 3 \times 5} - \sqrt{2 \times 2 \times 2 \times 2 \times 5}$

$= 2(2 \sqrt{5} ) + 8(3 \sqrt{5} ) - (4 \sqrt{5} )$

$= 4 \sqrt{5} + 24 \sqrt{5} - 4 \sqrt{5}$

$= 24 \sqrt{5} (ans)$

How do you determine whether you are finding a percent of increase or a percent of decrease between two values? Explain.

Slav-nsk [51]

Answer:

Increase:

It will have increase when y>x

so, percentage of increase is

$=\frac{y-x}{x}\times 100$

Decrease:

It will have decrease when x>y

so, percentage of decrease is

$=\frac{x-y}{x}\times 100$

Step-by-step explanation:

Let's assume initial value as x

assume final value as y

Increase:

It will have increase when y>x

so, percentage of increase is

$=\frac{y-x}{x}\times 100$

For example:

Initial value is 40

So, x=40

Final value is 50

so, y=50

now, we can find percentage in increase

$=\frac{50-40}{40}\times 100$

$=25$

Decrease:

It will have decrease when x>y

so, percentage of decrease is

$=\frac{x-y}{x}\times 100$

For example:

Initial value is 50

So, x=50

Final value is 40

so, y=40

now, we can find percentage in decrease

$=\frac{50-40}{40}\times 100$

$=25$

4x + 2y=4 and 3x -y= -7

Molodets [167]

Answer:

y = 4

x = -1

Step-by-step explanation:

4x + 2y = 4 Eq. 1

3x - y = -7 Eq. 2

from the Eq. 2

3x = y - 7

3x + 7 = y Eq. 3

Replacing the value of the Eq. 3 in the Eq. 1

4x + 2(3x+7) = 4

4x + (2*3x + 2*7) = 4

4x + (6x + 14) = 4

10x + 14 = 4

10x = 4 - 14

10x = - 10

x = -10/10

x = -1

from the Eq. 3

3x + 7 = y

3*-1 + 7 = y

-3 + 7 = y

4 = y

Check:

from the Eq. 1

4x + 2y = 4

4*-1 + 2*4 = 4

-4 + 8 = 4
