Twice a number added to six results in thirsty

Mathematics
1 answer:
horsena [70]3 years ago
7 0

Answer: 6+2n=30

Step-by-step explanation:

Since you did not say what you need to do, I will assume that you need to write an equation.

In order to solve this exercise it is important to remember the following:

1. The word "Twice" indicates you must multiply by 2.

2. The word "result" indicates an equal sign = .

Then, based on the explained above, you know that "Twice a number" can be represented with the following expression:

2n

Where "n" is the number mentioned.

Then, you know that "Twice a number added to six" can be expressed as following:

6+2n

 Therefore, you can conclude that "Twice a number added to six results in thirsty" can be represented with the following equation:

6+2n=30

During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by
Alja [10]

Answer:

The numbers of measure of music played are 1 and 7

Step-by-step explanation:

Given

s = 10|x - 4| + 50

Required

Solve for x when s = 80

Substitute 80 for x

80 = 10|x - 4| + 50

Subtract 50 from both sides

80 - 50= 10|x - 4| + 50 - 50

30= 10|x - 4|

Divide through by 10

\frac{30}{10}= \frac{10|x - 4| }{10}

3= |x - 4|

Reorder

|x - 4| = 3

This can be split into

x - 4 = 3 or x - 4 = -3

Solve for x

x = 4 + 3 or x = 4 - 3

x = 7 or x = 1

Hence:

<em>The numbers of measure of music played are 1 and 7</em>

FIRST TO ANSWER, would be marked as brainliest:)
boyakko [2]

Answer:

100 Cos 40° + 100 Sin 40° ≈ 141 yards

Step-by-step explanation:

From the diagram, side x is adjacent to the angle 40° while side y is the opposite to that same angle

This means that;

Cos 40° = x/100

x = 100 Cos 40°

Sin 40° = y/100

y = 100 Sin 40°

Therefore, total distance walked = x + y

                         "                             = 100 Cos 40° + 100 Sin 40° ≈ 141 yards

You need to solve a system of equations. You decide to use the elimination method. Which of these is not allowed?
Serggg [28]

Answer:

B

Step-by-step explanation:

The <u>Elimination Method</u> is the method for solving a pair of linear equations which reduces one equation to one that has only a single variable.

  • If the coefficients of one variable are opposites, you add the equations to eliminate a variable, and then solve.
  • If the coefficients are not opposites, then we multiply one or both equations by a number to create opposite coefficients, and then add the equations to eliminate a variable and solve.

When multoplying the equation by a coefficient, we multiply both sides of the equation (multiplying both sides of the equation by some nonzero number does not change the solution).

So, option B is not allowed (it is not allowed to multiply only one part of equation)
