So we don't know how old Kim is.
Jordan is 7 years older, and 4x of Jordan's age equals to 200.

So Jordan is 50 because 50 x 4 = 200.
Back to Kim, 50 - 7 = 43. Kim is 43.

Now, you write the equation. I helped you alot.

Kim is x
Jordan is x+7
Jordan x 4 = 200

Therefore 4(x+7) = 200
X+7 = 50
X = 43

Kim is 43, Jordan is 50.

Suppose you want to get a loan for $ 5 , 000 at an interest rate of 5.3 % for 2 years to be paid back in 24 monthly installments

swat32

Answer:

monthly payment = $56.445

Step-by-step explanation:

given data

loan = $5000

interest rate r = 5.3 % = 0.053

time t = 2 year = 24 months

solution

we will use here amount of the monthly payments formula that is

monthly payment = principal × $\frac{r}{1+(1-r)^{-t}}$ ................1

put here value and we get

monthly payment = 5000 × $\frac{0.053}{1+(1-0.053)^{-24}}\\$

monthly payment = $56.445

Answer:

i hope this helps

Step-by-step explanation:

2 $x^{2}$ -16=0

+16 +16

2 $x^{2}$ =16

÷2 ÷2

$x^{2}$ = 8

$\sqrt{x^{2} }$ = $\sqrt{8}$

x= $\sqrt{8}$

-5 $x^{2}$ +9=0

-9 -9

-5 $x^{2}$ =-9

÷-5 ÷-5

$x^{2}$ =1.8

$\sqrt{x^{2} }$ = $\sqrt{1.8}$

x= $\sqrt{1.8}$

6 $x^{2}$ -15=27

+15 +15

6 $x^{2}$ =42

÷6 ÷6

$x^{2}$ =7

$\sqrt{x^{2} }$ = $\sqrt{7}$

x= $\sqrt{7}$

Find the first five terms of the recursive sequence <br> an=-6an-1 where a1=4.5

grandymaker [24]

Answer:

4.5, -27, 162,-972, 5832

Step-by-step explanation:

The given recursive definition is,

$a_n=-6a_{n-1}, a_1=4.5$

This will form a geometric sequence with first term 4.5 and common ratio r=-6.

When n=2, we have:

$a_2=-6a_1 \\ \implies \: a_2=-6 \times 4.5 = - 27$

When n=3, we get:

$a_3=-6a_2 \\ \implies \: a_3=-6 \times - 27 = 162$

When n=4, we get:

$a_4=-6a_3 \\ \implies \: a_4=-6 \times 162 = - 972$

When n=5, we get:

$a_5=-6a_4 \\ \implies \: a_5=-6 \times - 972 = 5832$

Therefore the first five terms are:

4.5, -27, 162,-972, 5832
