Solve for x: 6x + 6 = 3x – 21

Mathematics
1 answer:
Volgvan4 years ago
6 0

Answer:

x = -9

Step-by-step explanation:

6x + 6 = 3x – 21

Subtract 3x from each side

6x-3x + 6 = 3x-3x – 21

3x+6 = -21

Subtract 6 from each side

3x+6-6 = -21-6

3x = -27

Divide by 3

3x/3 = -27/3

x = -9

ia is the Initial Amount, which is 7000

.per is the recent, in this case is .2

and finally x, which is the amount of years. this is 4

If you put this into a scientific calculator:   7000(1+.02)^{4} = y    you will get

Help please, I don't understand :(
exis [7]

Answer:

38 = JKL

Step-by-step explanation:

JKM = JKL + LKN + NKM

Substituting what we know

104 = JKL + LKN +33

KN  bisects LKM so NKM =  LKN

33 =  LKN

104 = JKL + 33 +33

104 = JKL + 33 +33

Combine like terms

104 = JKL +66

104 - 66 = JKL

38 = JKL

Which classification best describes the following system of equations? 3x+6y-12z=36, x+2y-4z=12, 4x+8-16z=48
Andrews [41]
(1) 3x+6y-12z=36
(2) x+2y-4z=12
(3) 4x+8y-16z=48

The first equation (1) is the second equation (2) multiplied by 3:
(2) x+2y-4z=12→3(x+2y-4z=12)→3x+6y-12z=36 (1)

The third equation (3) is the second equation (2) multiplied by 4:
(2) x+2y-4z=12→4(x+2y-4z=12)→4x+8y-16z=48 (3)

The equations are linearly dependent, Then the system of equations is dependent, and then consistent too.

Novay_Z [31]

Answer:

3/8 was the swimming segment!

Step-by-step explanation:

We only need to subtract the bike and running segment from the total distance:

15 11/16 - 12 1/4 - 3 1/16

15.6875 - 12.25 - 3.0625 = 0.375 = 3/8
