Answer:

1/4

Step-by-step explanation:

This is an event of 1/4 cards

If events became two different numbered cards with no replacement it would become 1/4 x 1/3 = 1/12

With replacement the odds get larger as there are more cards if picking two specified as random.  1/4 x 1/4 = 1/16

if it was the same number and not replaced it becomes 0/12 as 1/4 x 0/3 = 0/12 = 0

Find angle B and angle E
Natali [406]

Answer:

x = 9, Angles are 54°

Step-by-step explanation:

First, we need to find x:

7x-9 = 5x+9

+9 +9

7x = 5x+18

-5x -5x

2x = 18

x = 9

Now, we plug our x value in to find our angles.

5(9) + 9 = 54

Angle B = 54°

7(9) - 9 = 54°

Angle E = 54°

(angles are the same due to AAA property)

X10+2y=50 pounds this is your answers because if you do 3 times what number is less than 50 but still is even because all you have afterwars are 10 so 10 is 30. then 30 +?=50 its 20 so 10 multply by two plus 3 multiply by 10 equals 50. hope this helps!!!!!!!!!!
