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.
It is a number that has a variable and the variable can change to anything that you multiply by the factor it sits with. So basically it’s a number (3) that multiplies by whatever y equals to.
Please mark this as the brainliest answer thank you !
Answer : - 4 + 3 = - 1
- 2 + 3 = 1
By half gives - 1/2 and 1/2
So midpoint (-1/2, 1/2)
Answer:
B) 8 and 24.
Step-by-step explanation:
Just by looking at the answer choices, since one number must be three times the other, we can determine that the correct answer is B.
Regardless, let's work this out mathematically. Let the first number be <em>a</em> and the second number be <em>b</em>.
Their difference is 16. Hence:

The first number is three times the second number. So:

Substitute:

Solve for <em>b</em>. Subtract:

And divide both sides by two:

So, the second number is 8.
And since the first number is three times the second, the first number is 24.
Our answer is B as expected.
I’m not 100% sure but I think it’s because 20/25 can still be simplified further, while the other 3 can’t.
