C+ax=dx<br><br><br>this one has all variables and no numbers
sergeinik [125]
That's OK, but you have not said which variable you want to solve it for.

<u>To solve for 'x':</u>
                                           <span>c + ax = dx

Subtract c from each side:    ax = dx - c

Subtract  dx  from each side:   ax - dx = -c

Factor the left side:                 x (a - d) = -c

Divide each side by (a - d) :      x = -c / (a - d)  or  <u>x = c / (d - a)</u> .

Answer:

\overline{BC} \cong  \overline{DC} because corresponding parts of congruent triangles ΔACD and ΔACB are Congruent

Step-by-step explanation:

Statements,                                                Reason

\overline{AC} bisects ∠BCD,                                      Given        

\overline{DC} \perp  \overline{AD}                                                    Given

∠CDA ≅ ∠CBA                                           Right angles are ≅

\overline{AC} \cong  \overline{AC}                                                     Reflexive property

ΔACD ≅ ΔACB                                           Hypotenuse Leg (HL) congrurency

\overline{BC} \cong  \overline{DC}                                                    CPCTC

Where:

CPCTC = Corresponding parts of Congruent Triangles are Congruent

⊥ = Perpendicular to

≅ = Congruent

∠ = Angle

Δ = Triangle.

Step-by-step explanation:

-6-5(4-6)

PEMDAS stands for parenthesis, exponent, multiply, divide, add, subtract. Let's follow those rules!

First, we'll do the parenthesis.

-6-20+30

Now we can just add and subtract everything together.

-6+10
