(18x + 36)/2 = -24

Do the opposite of PEMDAS. Note the equal sign. What you do to one side you do to the other. Isolate the x.

First multiply 2 to both sides

(18x + 36)/2(2) = -24(2)

18x + 36 = -24(2)

18x + 36 = -48

Isolate the x. Subtract 36 from both sides

18x + 36 (-36) = - 48 (-36)

18x = -48 - 36

18x = - 84

Isolate the x, divide 18 from both sides

18x/18 = -84/18

x = -84/18

x = -4.67 (rounded)

-4.67 rounded should be your answer

hope this helps

Two consecutive whole numbers are n-1 and n
Orlov [11]

a. n-(n - 1) = 1

b. n( n - 1) = n² - n

c. (n - 1) + n = 2n - 1

d. (n - 1) + n = 2n - 1

<h3>Solution:</h3>

General Rule for Equation Solving

  • Remove parentheses and combine like terms to simplify each side of the equation.
  • To isolate the variable term on one side of the equation, use addition or subtraction.
  • To find the variable, use multiplication or division.

Given two consecutive numbers , (n - 1) , n

simplifying :

n - (n - 1)

= n -1(n - 1)

= n - n + 1

= 1

multiplying :

n( n -1)

= n² - n

simplifying :

(n-1) + n

= n - 1 + n

= 2n -1

by adding two numbers :

(n - 1) + n

= n -1 + n

= 2n - 1

Which linear inequality is represented by the graph?
Tamiku [17]

Answer:

Option (4)

Step-by-step explanation:

From the graph attached,

A dotted line passes through two points (3, 1) and (-3, -3)

Let the equation of the given line is,

y = mx + b

where 'm' = slope of the line

b = y-intercept

Slope of a line passing through (x_1, y_1) and (x_2,y_2) is,

m = \frac{y_2-y_1}{x_2-x_1}

For the given points,

m = \frac{1+3}{3+3}

m = \frac{2}{3}

y-intercept 'b' = -1

Therefore, equation of the given line will be,

y=\frac{2}{3}x-1

Since graphed line is a dotted line so it's representing an inequality(having < or > sign)

And the shaded part is below the dotted line,

Inequality will be,

y < \frac{2}{3}x-1

Therefore, Option (4) will be the answer.

6 times 7 to the second power
Travka [436]
Hello!

To solve this question, we must first add the exponent into the number 7 before multiplying it by the number 6. 

7 to the second power simply means 7x7. 

7x7= 49

Now that the exponent is in the equation, we can multiply 49 by 6 to find your final answer. 

6 x 49 = 294

I hope this helps answer your question! Have a great day!
