The correct answer for the exercise shown above is:

 zero (0)

 The explanation is shown below:

 1. You have the following expression given in the problem above:

 7/6a

 2. By definition, <span>the nonpermissible replacement for a is the value that make the denominator equal to zero.

 3. Keeping this on mind, you have:

Dharma and Jorge are looking at cell phone plans. A
riadik2000 [5.3K]

Answer:

Dharma and Jorge should purchase a group plan.

They could save $9.55

Step-by-step explanation:

A group plan will cost an average of $135.95 per month.

An individual plan will cost an average of $72.75 per month.

Two individual plans will cost an average of

\$72.75\cdot 2=\$145.50

per month.

Since $145.50 > $135.95,  Dharma and Jorge should purchase a group plan.

They could save

\$145.50-\$135.95=\$9.55

Find the values of X and Y that makes these triangles congruent by the HL theorem
muminat

Answer:

C. x = 3, y = 2

Step-by-step explanation:

If both triangles are congruent by the HL Theorem, then their hypotenuse and a corresponding leg would be equal to each other.

Thus:

x + 3 = 3y (eqn. 1) => equal hypotenuse

Also,

x = y + 1 (eqn. 2) => equal legs

✔️Substitute x = y + 1 into eqn. 1 to find y.

x + 3 = 3y (eqn. 1)

(y + 1) + 3 = 3y

y + 1 + 3 = 3y

y + 4 = 3y

y + 4 - y = 3y - y

4 = 2y

Divide both sides by 2

4/2 = 2y/2

2 = y

y = 2

✔️ Substitute y = 2 into eqn. 2 to find x.

x = y + 1 (eqn. 2)

x = 2 + 1

x = 3

The perimeter of the triangle below is 99 units. Find the length of side WX.
frez [133]

Answer:

14

Step-by-step explanation:

Perimeter= 99

XV+VW+WX=99

4z+3z+1+z+2=99

8z+3=99

8z= 96

z=96/8

z= 12

WX= z+2= 12+2= 14.

Hope it helps :-)
