Answer:
The answer to all of those questions would be x=-1.8
Step-by-step explanation:
7x(x + 1.8) = 0 - Distribute through the Parenthesis -
7x^2 + 12.6x = 0
x(7x + 12.6) = 0
x = 0
7x + 12.6 = 0
7x = -12.6
x = -12.6/7
x = -1.8
so x = 0 or x = -1.8
Answer:
1. 247 mg ÷ 10 = 24.7 cg
2. 247 mg ÷ 100 = 2.47 dg
247 mg ÷ 1000 = 0.247 g
Step-by-step explanation:
1. To convert from 'mg' to 'cg', you must divide by 10 because 'cg' consists of 10 mg.
2. To convert from 'mg' to 'dg', you must divide by 100 because 'dg' consists of 100 mg.
3. To convert from 'mg' to 'g', you must divide by 1000 because 'g' consists of 1000 mg.
Step-by-step explanation:
