Steps for solving 6x - 18 = 54 are shown.
explain how step 1 solve the equation.

x = 12

Step 1 helps solve the equation, for it helps isolate the x, which is what you are solving for.

Step-by-step explanation:

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

Step 1: Add 18 to both sides.

6x - 18 (+18) = 54 (+18)

6x = 54 + 18

6x = 72

Step 2: Divide 6 from both sides:

(6x)/6 = (72)/6

x = 72/6

x = 12

x = 12 is your answer.

Step-by-step explanation:

Add by 18 from both sides of equation.

Add numbers from left to right.

Divide by 6 from both sides of equation.

Simplify, to find the answer.

, which is our answer.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
