Answer:
Step-by-step explanation:
To find the LCM of any integer, we take the product of all the <em>highest powers</em> of the factors that appear in the numbers. Factoring our three given expressions gives us the products
Our LCM will be a product of some powers of 
, 
, and 
. The most each factor occurs in the three expressions is once, so our least common multiple is
which can be simplified to 
The slope would be 1.2. If they are parallel lines, they have the same slope. :)
Answer:
B. -20
Step-by-step explanation:
8/d = -12/30
We can use cross products to solve
8 * 30 = d* -12
240 = -12 d
Divide each side by -12
240/-12 = -12d/-12
-20 = d
2/6 = 1/3 * 180=
Hope this helps!
Answer:
-16
Step-by-step explanation:
x = -3 is less than -2, so you should use the first equation 5x-1
thus, 5(-3)-1 = -16
