You can use the formula P=A(i/1-(1+i)-n) monthly payment on a loan of A dollars that is paid back in equal monthly payments over
Dafna11 [192]

Answer:

$48.54

Explanation:

We must express the interest rate on a monthly basis.

i = 8 %/yr = 0.6667 %/mo = 0.006 667

A = $4000

n = 120 mo

P = A(\frac{i}{1-(1+i)^{-n}})

P = 4000(\frac{0.006667 }{1-(1+0.006667)^{-120}})

P = \frac{26.67}{1-0.006667^{-120}}

P = \frac{26.67}{1-0.4505}

P = \frac{26.67}{0.5495}

P = 48.531

The banks round up the numbers, so Seki’s monthly payment is $48.54.

Read the question and help me, please.​

<h3>Answer: B) 6</h3>

===============================================

Explanation:

Add the equations by adding the terms straight down.

The x terms add to x+x = 2x.

The y terms add to y+(-y) = y-y = 0y = 0, so the y terms go away

The constants add to 5+7 = 12

The z terms add to -z+z = 0z = 0 and those go away as well

After all that adding, we have 2x = 12 which solves to x = 6 after dividing both sides by 2.

What does n equal in this equation? n-2=(10n+4)/2 (btw 10n+4 over 2)
tia_tia [17]
N-2=(10n+4)/2
Multiply each side by 2
2(n-2)=10n+4
Expand the brackets
2n-4=10n+4
Subtract 4 from each side
2n-8=10n
Subtract 2n from each side
-8=8n
Divide each side by 8 
-1=n

Hope this helped
