Answer:

From a standard deck of cards, one card is drawn. What is the probability that the card is black and a jack? P(Black and Jack) P(Black) = 26/52 or ½ , P(Jack) is 4/52 or 1/13 so P(Black and Jack) = ½ * 1/13 = 1/26 A standard deck of cards is shuffled and one card is drawn. Find the probability that the card is a queen or an ace.

Samantha measured two of the angles in PQR and found that they had measures of 65° and 70°. Then, she measured two of the angles
Vlad [161]
The two triangles are similar.

The angles of a triangle sum to 180°.  Using the known angles in the first triangle, we find the missing angle measure:
180-(65+70) = 180-135 = 45

We do the same for the second triangle:
180-(65+45) = 180 - 110 = 70

Any two triangles that have all 3 angles congruent is similar by AAA.

4(x – 5) +2x = -14<br> So x=?
Nikolay [14]

Answer:

x=1

Step-by-step explanation:

Step 1:Simplify both sides of the equation

4(x-5)+2x=-14

(4)(x)+(4)(-5)+2x=-14

4x+-120+2x=-14

4x+2x+-20-14

6x+-20=-14

6x-20=-14

Step 2: Add 20 to both sides

6x-20+20=-14+20

6x=6

Step 3: Divide both sides by 6

6x/6=6/6

x=1
