B-3a=2 3B- 6a=12 solve algebraicly show steps
lora16 [44]
B - 3A = 2
3B - 6A = 12

(2)B - (6)A =4
3B - 6A = 12

Subtract

-B = -8
B = 8

Plugin 8 for B

8 - 3A = 2
8 = 3A + 2
6 = 3A
2 = A

(Double checking)
3(8) - 6A = 12
-6A = 12-24 = -12
- 6A = -12
Divide by -6
A= 2
It works

A = 2. B = 8. Hope this helps

KIM [24]

Answer:

.26

Step-by-step explanation:

.59 = M

.39 = A

.24= M∩A

M'∩A'= ?

M'∩A'= (M∪A)' (we call this demorgan's law)

MUA= M+A-M∩A

.59+.39-.24= .74

1-.74= .26

lesantik [10]

Answer:

yes

Step-by-step explanation:

We need to check if the circle with a circumference of 15 feet is smaller then 7 feet. If so it possible.

Formule for circular circumference = pi * diameter, which should be 15.

So pi * d =15

There fore d = 15/pi

d = 4.77464829275686 feet, which is smaller then 7 feet, so it will fit easilly.
