The sum of three numbers is 137. The second number is 4 more than two times the first number. The third number is less than three times the first number. Find the three numbers.

Answers

Answer:

23, 50, 64

Step-by-step explanation:

137 = 23 + 50 + 64

Let the first number be x

Second number: 2x+4

Third number: 3x-5

Write the equation:

x + (2x + 4) + (3x-5) = 137

Solve for "x"

6x - 1 = 137

6x = 138

x = 23

Plug x (23) into the equation:

x + (2x + 4) + (3x-5) = 137

23 + 2(23) + 4 + 3(23) - 5 = 137

(23 + 46 + 4 + 69) - 5 = 137

142 - 5 = 137

Which line uses all trochees?
A. Correct, the mall is over there
B. Roadrunners and barbecue
C. Toy store sausages swung by
D. Ask me questions now or later

Answers

Answer:

I believe it is c

Step-by-step explanation:

The metrical pattern of a trochee is said to have a "falling rhythm" because the emphasis comes at the beginning of the foot: "da-dum da-dum." This falling rhythm is the exact opposite of the iambic "rising rhythm" that is more common in both poetry and speech, so the cadence of trochaic meter tends to sound a little unnatural to the ear. While for this reason trochees are relatively rare in most poetry, the "downward" motion and "backward" orientation of trochees actually makes them a popular foot for writing about dark subjects like madness and death.

Answers

Answer:

A special right triangle is a right triangle having angles of 30, 60, 90, or 45, 45, 90. Knowledge of the ratio of the length of sides of a special right triangle enables us to solve for any missing part of the triangle. The ratio of the side lengths of a special right triangle with angles of 30, 60, 90 is 1:sqrt(3):2, while the ratio of the side lengths of a special right triangle with angles of 45, 45, 90 is 1:1:sqrt(2).

Which of the following is a characteristic of a deferred payment plan? (2 points)
There is an introductory period where no interest is accrued.
The item purchased is used as collateral until the balance is paid in full.
A down payment is always required.
A certain number of payments must be made before the product is owned.

Answers

A characteristic of a deferred payment plan is that the item purchased is used as collateral until the balance is paid in full.

A deferred payment plan is a form of credit purchase, a way to pay for an item in arrears. The payment is usually divided into several installments, which are distributed over a certain period of time. Interest and fees are often added, which in the end makes the purchase considerably more expensive than if you had paid in cash.

Thus, through this payment system, the asset is delivered to the buyer before the payment is completed, thereby constituting the asset itself as an enforceable guarantee of payment compliance.

What is the sum of the roots of the equation 2 x^2 + 5 x − 3 = 0?
a)-3.5
b)-2.5
C)-1.5
D)2.5

Answers

Answer:

B) -2.5

Step-by-step explanation:

2x^2 + 5x -3 = 0

(2x - 1)(x + 3) = 0

2x - 1 = 0; 2x = 1, so x = 1/2 = ROOT 1

x + 3 = 0, so x = -3 = ROOT 2

Now add the roots: -3 + 1/2 = - 2 1/2, so the answer is B.

in 2000 the population of India was around 1.053 billion , and in 2016 the population hit 1.327 billion people . if India's population continues to grow at this same rate in what year was the population of India reach 3 billion people. ​

Answers

Answer:

The population of India would reach 3 billion in about 112 years (year 2128)

Step-by-step explanation:

1. subtract 1.327 billion by 1.053 billion  (1.327-1.053)

2. The answer you should get is 274,000,000 (two hundred seventy four million)

3. multiply 274,000,000 by 7 (amount of people required to reach about 3 billion)

4. add the product (ans to multiplication problem) to 1.327 billion. (you should get 3.245 billion (3245000000).

5. multiply 16 by 7 (16x7) to get the number of years to reach 3 billion (maybe 112)

6. Add the product to 2016

7. Therefore you get the year 2128.

Using Cramer's Rule, the solution to the system of equations

6x−5y=−4−7x+3y=−1

can be written in the form (DxD,DyD).

What is the value of Dx?

Answers

Using Cramer's rule it is found that Dx = -34.

In Cramer's rule, we have three matrices.

x is a matrix in which the first column is the coefficients that multiply x, and the second are the coefficients on the right side of the equality.y is a matrix in which the first column is composed by the coefficients on the right side of the equality and the second is the coefficients that multiply y.M is a matrix in which the first column is the coefficients that multiply x, and the second is the coefficients that multiply y.

In this problem, the system is:

[tex]6x - 5y = -4[/tex]

[tex]-7x + 3y = -1[/tex]

Matrix x is given by:

[tex]x = \left[\begin{array}{ccc}6&-4\\-7&-1\\\end{array}\right][/tex]

It's determinant is given by:

[tex]Dx = 6(-1) -(-4)(-7) = -6 - 28 = -34[/tex]

Thus, Dx = -34.
