Multiply the second equation by 2 so that its 
6x+4y=-30
then subtract 
6x+y=-39
6x+4y=-30
= -3y=-69
divide by -3 to isolate the y
then you get y=23
substitute the y value back into one of the equations to solve for x.
6x+23=-31
solve like you always do and you'll get your x
Congratulations, you solved a problem.

Cerrena [4.2K]

The purchase of the hydroponic system by Ingrid Nilsen for $4,000 with a 20% down payment at 10% APR for 36 months, and the related calculations, are as follows:

a) down payment = $800.00 ($4,000 x 20%)

b) amount financed = $3,200 ($4,000 - $800)

c) monthly payment = $103.25

d) total amount repaid = $4,517

e) finance charge = $517

<h3>How is periodic payment computed?</h3>

The amount of the periodic payment, finance charge, and total repayment can be computed using an online finance calculator as follows:

<h3>Data and Calculations:</h3>

Auto Price = $4,000

Loan Term = 36 months

Interest Rate = 10%

Down Payment = $800 ($4,000 x 20%)

Monthly Payment  = $103.25

Total Loan Amount $3,200.00

Upfront Payment = $800.00 ($4,000 x 20%)

Total of 36 Loan Payments = $3,717. ($103.25 x 36)

Total Loan Interest = $517

Total Cost (price, interest, tax, fees) = $4,517

Thus, Ingrid Nilsen repaid a total of $4,517 with $517 in interest (finance charge).

svp [43]

Step-by-step explanation:

The area that cow can graze is in the form of semicircle.

Radius of semicircle

Length of rope =14 m

Required area = 1/2 ×πr

=1/2×22/7×r^2

=1/2×22/7×14×14

=308m2

Chris used 45 meters of fencing to enclose a circular garden. What is the approximate radius of the garden,rounded to the neares
kobusy [5.1K]
The length of the fencing corresponds to the length of the perimeter of the garden:
p=45 m
We also know that the perimeter of a circle is given by:
p=2 \pi r
where r is the radius of the circle.

Putting together the two equations, we have
2 \pi r = 45
from which we can find r, the radius of the garden:
r= \frac{45}{2 \pi}= \frac{45}{2 \cdot 3.14}=7.17 m
