Help me plzzzzzzzzz<br> solve for x
Svet_ta [14]

Answer:

7) \frac{x+20}{x}=\frac{46}{30}

30(x+20)=46x

30x+600=46x

46x-30x=600

16x=600

x=75/2

x=37.5

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

8) \frac{10}{3x+1} =\frac{22}{7x-1}

10(7x-1)=22(3x+1)

70x-10=66x+22

70x-66x=22+10

4x=32

x=\frac{32}{4}

x=8

barxatty [35]
<h3>Answer:</h3>

$808.38

<h3>Explanation:</h3>

The formula for the payment amount (A) on principal P at interest rate r compounded monthly for a loan period of t years is ...

... A = P(r/12)/(1 -(1 +r/12)^(-12t))

For the main loan, the payment is ...

... A = 0.80·145000·(.0475/12)/(1 -(1 +.0475/12)^(-12·30)) = 605.11

For the piggyback loan, the payment is ...

... A = 0.20·145000·(.07525/12)/(1 -(1 +.07525/12)^(-12·30)) = 203.27

So, the total of monthly payments for the two loans is ...

... $605.11 +203.27 = $808.38
