Answer:
120 = 2³ × 3 × 5
210 = 2 × 3 × 5 × 7
LCM(120 ; 210) = 2³ × 3 × 5 × 7 = 840
Answer:
x=21
Step-by-step explanation:
x=9+12 x=21
Subtracting from both sides gives us the false statement so this equation can never be true and thus has no solutions.
Answer:

Step-by-step explanation:
Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 3y + 2x = 1 into this form
Subtract 2x from both sides
3y = - 2x + 1 ( divide all terms by 3 )
y = - x + ← in slope- intercept form
with slope m = - → A
