1 is 117 because 18x6.5 is 117
Answer:
x = 4
, y = 3
Step-by-step explanation:
Solve the following system:
{2 x - 3 y = -1 | (equation 1)
y = x - 1 | (equation 2)
Express the system in standard form:
{2 x - 3 y = -1 | (equation 1)
-x + y = -1 | (equation 2)
Add 1/2 × (equation 1) to equation 2:
{2 x - 3 y = -1 | (equation 1)
0 x - y/2 = (-3)/2 | (equation 2)
Multiply equation 2 by -2:
{2 x - 3 y = -1 | (equation 1)
0 x+y = 3 | (equation 2)
Add 3 × (equation 2) to equation 1:
{2 x+0 y = 8 | (equation 1)
0 x+y = 3 | (equation 2)
Divide equation 1 by 2:
{x+0 y = 4 | (equation 1)
0 x+y = 3 | (equation 2)
Collect results:
Answer: {x = 4

Answer: the monthly payment is $1530.1
Step-by-step explanation:
The cost of the house is $319,000.
The down payment made is 20%. This means that the amount paid as down payment is
20/100 × 319000 = 63800
The balance to be paid would be
319000 - 63800 = $255200
We would apply the periodic interest rate formula which is expressed as
P = a/{[(1+r)^n]-1}/[r(1+r)^n]
Where
P represents the monthly payments.
a represents the amount of the loan
r represents the annual rate.
n represents number of monthly payments. Therefore
a = $255200
r = 0.06/12 = 0.005
n = 12 × 30 = 360
Therefore,
P = 255200/{6.0226 -1}/[0.005(6.0226)]
P = 255200/166.79
P = 1530.1
Theoretically she couldn’t spend that amount if money and thus her account balance will be negative. -61.72, to be precise.
