The correct equation is n - 31 = 52

To check the solution, substitute 83 for the variable in the equation

This is an addition problem.

To solve the equation, add 31 to both sides.

Step-by-step explanation:

A number decreased by thirty-one is fifty-two

That means:

  • Subtract 31 from a number
  • The difference equal 52

Assume that the number is n

∵ The number is n

∵ When n decreased by 31 the answer is 52

∴ The equation is n - 31 = 52

The correct equation is n - 31 = 52

∵ n - 31 = 52

- To find n add 31 to both sides of the equation

∴ n - 31 + 31 = 52 + 31 ⇒ addition property

∴ n = 83

-To check the equation substitute n by 83 in the left hand side, the

  answer must be equal the right hand side

∵ Left hand side = 83 - 31 = 52

∵ Right hand side = 52

∴ n = 83 is correct answer

To check the solution, substitute 83 for the variable in the equation

This is an addition problem.

To solve the equation, add 31 to both sides.

Answer:

The correct equation is n minus 31 = 52.

To check the solution, substitute 83 for the variable in the equation.

This is a subtraction problem.

To solve the equation, add 31 to both sides.

Step-by-step explanation:

I took the exam. these are right

These are WRONG

The correct equation is n + 31 = 52.

To check the solution, substitute 21 for the variable in the equation.

This is an addition problem.

To solve the equation, subtract 31 from both sides.

Solve for the indicated angle to the nearest tenth of a degree.<br> o<br> 18<br> 25
Sonbull [250]

Answer:

\theta=54.2^\circ

Step-by-step explanation:

<u>Right Triangles</u>

The ratios of the sides of a right triangle are called trigonometric ratios.  Each acute angle has an adjacent side and an opposite side. The trigonometric ratios are defined upon those sides.

The tangent ratio is defined as:

\displaystyle \tan\theta=\frac{\text{opposite side}}{\text{adjacent side}}

The opposite side is 25 and the adjacent side is 18, thus:

\displaystyle \tan\theta=\frac{25}{18}=1.389

The angle is calculated by using the inverse tangent function:

\theta=\arctan 1.389

\boxed{\theta=54.2^\circ}

Whats the solution of 6x+18=12x.
Vadim26 [7]

Answer:

<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>3</u></em></h2>

Step-by-step explanation:

6x + 18 = 12x

=> 18 = 12x - 6x

=> 18 = 6x

=  > x =  \frac{18}{6}

=> <em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>3</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
