So if PT=TQ and TQ=7x-9

PT=5x+3=TQ=7x-9

5x+3=7x-9
minus 5x both sides
3=2x-9
add 9 both sides
12=2x
divide 2
6=x

PT=5x+3
PT=5(6)+3
PT=30+3
PT=33

PT=QT=33
x=6

If the purchase price for a house is $309,900, what is the monthly payment if you put 20% down for a 30 year loan with a fixed r

Nookie1986 [14]

Answer:

$1486.41.

Step-by-step explanation:

Purchase price = $309,900

Down payment percent = 20 %

Remaining amount Percentage = 100-20 = 80%

Mortgage amount = $309900 \times 0.80$

= $247920$

Formula of monthly payment : $P =\frac{\frac{rM}{1 -(1 +\frac{r}{n})^-{nt}}}{n}$

where P = the payment,

r = the annual rate =6% = 0.06

M = the mortgage amount = $247920

t = the number of years=30

n = the number of payments per year= 12

Substitute the values.

$P =\frac{\frac{0.06 \times 247920}{1 -(1 +\frac{0.06}{12})^-{12\times 30}}}{12}$

$P=1486.40566196$

Hence the monthly payment is $1486.41.

Thus Option C is correct.

Step-by-step explanation:

1. 48

= 16 × 3

= 48

2. 25

= 27 -7 + 5

= 32 - 7 

= 25

3. 9

= 17 - 8

= 9

4. 36

= 144 ÷ 36 × 8 + 4

= 4 × 8 + 4

= 32 + 4 

= 36

5. 2

= 32 ÷ 16

= 2

6. 10

= 16 - 15 + 9

= 25 - 15

= 10

7. 16

= 9 + 25 - 2 × 9

= 9 + 25 - 18

= 34 - 18

= 16

8. 47

= 121 - 42 - 64 ÷ 2

= 121 - 42 - 32

= 121 - 74

= 47
