Answer:

D. x=1

Step-by-step explanation:

Image can be rewritten as 3x + 6 = 9.

Solve for x.

3x +6 = 9

Isolate x by subtracting 6 from both sides.

3x = 3

Get rid of the 3 by dividing by 3 on both sides.

x = 1

Least common multiple of 30 25 4

White raven [17]

Answer:

The least common multiple of 30, 25, 4 is 150.

Step-by-step explanation:

The given numbers are 30, 25 and 4.

The factors of given numbers are

$30=2\times 3\times 5$

$30=5\times 5$

$4=2\times 2$

The L.C.M of given numbers is a smallest number that divides the given numbers completely.

$L.C.M.=\frac{2\times 3\times 5\times 5\times 5\times 2\times 2}{5\times 2}$

$L.C.M.=2\times 3\times 5\times 5\times 2=150$

Therefore the least common multiple of 30, 25, 4 is 150.
