Answer:
x = 4
Step-by-step explanation:
3(4x - 7) = 27
distribute the 3
(3 * 4x) + (3 * -7) = 27
12x + (3 * -7) = 27
12x - 21 = 27
add 21 to both sides of the equations
12x - 21 + 21 = 27 + 21
12x = 27 + 21
12x = 48
divide both sides by 12
12x/12 = 48/12
x = 48/12
x = 4/1
x = 4
-- the greatest common factor of the 15, the 9, and the 24 is 3 .
-- the greatest common factor of the b⁴, the b⁵, and the b³ is b³.
-- the greatest common factor of the c³, the c², and the c¹, is c¹.
-- the greatest common factor of the d², the d¹, and the d³ is d¹.
-- SO, the greatest common factor of the whole thing is ( 3 b³ c d ) .
Can you factor that out of the big mess ?
Please try it.
You should get (3 b³cd) (5 bc²d - 3 b²c - 8 d²) .
Given:
The equation is
To find:
The solution of the given equation.
Solution:
We have,
Subtracting both sides by 20, we get
Multiply both sides by 3.
Therefore, the solution of the given equation is .

Answer:
Step-by-step explanation:
The position function for the free-falling object is , where t is measured in seconds and y is measured in meters. The velocity function is obtained by deriving it:
, where v is measured in meters per second.
Velocities at given times are, respectively:
