9c + 6 = 24 what does the variable c equal

NARA [144]

Answer:

c = 2

Step-by-step explanation:

Isolate the variable, c. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& roots)

Multiplications

Divisions

Additions

Subtractions

First, subtract 6 from both sides of the equation:

9c + 6 (-6) = 24 (-6)

9c = 24 - 6

9c = 18

Next, divide 9 from both sides of the equation:

(9c)/9 = (18)/9

c = 18/9

c = 2

c = 2 is your answer.

1. Find the distance between two

BigorU [14]

Answer:

$\mathrm{D)\:}9.4\: \mathrm{units}$

Step-by-step explanation:

Solution 1:

Notice the $x$ coordinate of both points are equal, meaning both points are on a vertical line. The distance between two points on a vertical line is the absolute difference of their y-coordinates. The absolute difference between $4.7$ and $-4.7$ is $|4.7-4.7|=\fbox{$9.4$}$ .
