Answer:

Step-by-step explanation:

Since we have 13 heart card then

p(heart) = 13/52

Since we have 12 picture card then

p(picture) = 12/52

Since we have 3 heart and picture (at the same time) card then

p(heart∩picture) = 3/52

finally,

the possibility that you are dealt a heart or a picture card = p(heart or picture)

p(heart or picture) = 13/52 + 12/52 - 3/52 = 22/52

Answer:

See below

Step-by-step explanation:

Use 5 for "x" or "a number" and see if the inequality is true.

a) =3 < 5+11 < 2 . . . . false. 16 is not less than 2

b) 7·5 ≥ 35 or 4·5 < -12 . . . . true. 35 = 35

c) -7 + 2·5 = 3 is at most 2 . . . . false. 3 > 2

d) 5·5 +3 = 28 is between 2 and 30 . . . . true.

6x – 4y = -5<br>4x + 5y = -11

kipiarov [429]

Answer:

x= -1.5, y= -1

Step-by-step explanation:

6x= -5+4y

x= (-5+4y) / 6

4((-5+4y) / 6) + 5y = -11

4(-5+4y) + 5*6y = -11*6

-20+16y+30y= -66

16y + 30y = -66+20 = -46

y(16 + 30) = -46

y= -46 / (16 + 30)

y= -46 / 46

y= -1

x= (-5+4(-1)) / 6

x= (-5-4) / 6

x= -9 /6

x= -1.5
