What is the value of x? 30 45 55 60

KATRIN_1 [288]

Answer:

$\boxed {\tt B. \ x=45}$

Step-by-step explanation:

x and 3x are on a straight line together. Therefore, they are supplementary and must add to 180 degrees.

Add x and 3x, and set that equal to 180.

$x+3x=180$

Combine like terms on the right side of the equation. Both x and 3x have a variable, so they can be added together.

$(x+3x)=180$

$4x=180$

Since we want to find x, we have to isolate x. x is being multiplied by 4. The inverse of multiplication is division. Divide both sides of the equation by 4.

$\frac{4x}{4} =\frac{180}{4}$
