The variable g represents the number of guests , and the variable c represents the cost in dollars. If there are 12 guest, how much will Scarlett’s birthday party cost? C=g

Since C = g

and g = 12

then the cost of the party = $12

  $12

Step-by-step explanation:

Put the value where the variable is and interpret the result:

  g = 12 . . . . the number of guests

  C = 12 . . . . using the given value in C=g.

The cost of Scarlett's birthday party is $12.

14

step-by-step explanation:

14 x 3 = 42

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
