28 days
If you are looking for how many days are in four weeks then 28.
ᴛʜᴇ ᴀɴsᴡᴇʀ ɪs 5.0 x 10^6
Separating the fraction into 2 fractions:
1.6 10^14
—— x ——
3.2 10^7
Dividing the numbers, and dividing the terms with the same base by subtracting their exponents:
0.5 x 10^14-7
Lastly, just subtract the exponents:
0.5 x 10^7
In scientific notation it would equivalent to:
0.5 x 10^6
Answer:
Step-by-step explanation:
Cindy is correcy because on "Step 1:" the multiplication was correctly distributed over the subtraction in paranthesis 5(x-2) = 5*x- 5*2 = 5x-10.
Henry was wrrong because he distributed 5 only over x and not over -2 as well 5(x-2) ≠ 5*x-2
There is no such thing as subtraction. Just something to think about :)
There are numbers and there is an operation called addition. Every number has an additive inverse, an opposite value.
Example: The opposite of 4 is -4.
When we do addition between numbers like 5 and the inverse of 2: 5 + -2 this is usually what we're thinking of when we talk about subtraction. We could write it as 5 - 2.
But anyway, to answer your question,
Subtraction and division are derived from the principle operations of ADDITION and MULTIPLICATION.
Answer:
2 hours is the answer because when you are rounding to the nearest tenth they both will be $15.70.
