Step-by-step explanation:

2. 13y=20x+3y    10y=20x

8x+y=180-13y      14y=180-8x

y=2x    plugging that into 14y=180-8x   28x=180-8x     36x=180   x=5

plug x into 10y=20x    10y=100    y=10

Michelle is debating between two different mortgages for $184,000. She found a 20-year fixed rate loan at 7.05% and 15-year fixed rate loan at the same rate. How much more interest will she pay for the 20-year loan versus the 15-year loan?

Answers

9514 1404 393

Answer:

  $45,081

Step-by-step explanation:

The amortization formula can be used to find the monthly payment.

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

For the 20-year loan with r=0.0705 and P=184,000, the monthly payment is ...

  A = $1432.08

The total amount repaid will be ...

  12×20×1432.08 = 343,699.20

__

For the 15-year loan with the same parameters, the monthly payment is ...

  A = 1658.99

and the total amount repaid is ...

  12×15×1658.99 = 298,618.20

The difference in these repayment amounts is the difference in interest charges:

  343,699.20 -298,618.20 = 45,081

The 20-year loan will cost $45,081 more than the 15-year loan.

What is the next term of the arithmetic sequence? -3,0,3,6,9,−3,0,3,6,9,minus, 3, comma, 0, comma, 3, comma, 6, comma, 9, comma

Answers

Answer:

12

Step-by-step explanation:

Given the arithmetic sequence :

-3,0,3,6,9

Using the relation :

Tn = a + (n- 1) d

d = common difference = t2 - t1 = 0 - (-3) = 3

The next term = 6th term ; n = 6

a = first term

T6 = - 3 + (6 - 1)3

T6 = - 3 + (5)3

T6 = - 3 + 15

T6 = 12

Luna entered a raffle for a new pair of running shoes. She purchased 20 tickets and was told that she had a 20% chance of winning. How many tickets were sold? P (Luna winning) = StartFraction Number of tickets purchased over Total number of tickets sold EndFraction. 20 percent = StartFraction 20 over x EndFraction. One-fifth = StartFraction 20 over x EndFraction. x = tickets

Answers

Answer:

100 tickets

Step-by-step explanation:

Probability of winning = amount of tickets purchased/Total number of tickets

20% = 20/total number of tickets

20/100 = 20/total number of tickets

cross multiply

20 * total number of tickets = 20 * 100

20 *  total number of tickets = 100

total number of tickets sold = 100 tickets

equation below for C.
C-S
De

Answers

Answer:

C = 71D + S

Step-by-step explanation:

The computation of the equation for C is as follows:

Given that

Yearly Depreciation = D

Cost = C

Salvage value = S

Number of years = 71

Based on the above information

The formula for the yearly depreciation i.e. D is

D = (C - S) ÷ 71

71D = C - S

71D + S = C

So, the equation would be

C = 71D + S

Answer: x = 17

Step-by-step explanation:

180 - 94 = 86

So all the inside angles of a triangle = 180

180 - 86 - 60 = 34

34/2 = 17

Answer:

it's answer is 17

Step-by-step explanation:

we know exterior angle of a triangle is equal to the sum of two opposite interior angles. So,

2x + 60° = 94°

2x = 94° - 60°

2x = 34°

x = 34° /2

x = 17°

The answer is A) (3.1, 2.2)

Answer:

A

Step-by-step explanation:

Given the 2 equations

y = 2x - 4 → (1)

2x + 4y = 15 → (2)

Substitute y = 2x - 4 into (2)

2x + 4(2x - 4) = 15 ← distribute and simplify left side

2x + 8x - 16 = 15

10x - 16 = 15 ( add 16 to both sides )

10x = 31 ( divide both sides by 10 )

x = 3.1

Substitute x = 3.1 into (1) and evaluate for y

y = 2(3.1) - 4 = 6.2 - 4 = 2.2

solution is (3.1, 2.2 ) → A
